Recording method and reproducting method

The application is to be that Dec 36 calendar year 2001, application number are 01821385.5, name is called dividing an application of " recording medium, recording method, reproducting method, pen recorder and transcriber " applying date.

Technical field

The present invention relates to a kind of CD media that allows high density data record and be used at the CD media identifying recording layer or from the method and apparatus of its rendering data.

Background technology

Recently, the recording density of CD media increases rapidly.In the situation of the CD media that allows the numerical data record, data recording, reproduction and management are normally carried out take piece as unit, every byte length with regulation.(such piece is known as " data block ".) the given address information of each data block.Data recording and reproduction reference address information are carried out.

For at a CD media identifying recording layer, store such as the user data of for example audio frequency, video and computer data with redundant data, for example be used for when reading the data of storing, detecting or the error check code (parity check code) of correction data mistake.Come conversion with the user data of redundant data according to a modulation code system that is well-suited for the characteristic of CD media recording and reconstruction signal.On CD media, data bit stream after the record coversion.A kind of known modulation code system that usually is used for CD media is run-length limited code.

Run-length limited code is determined data bit stream after the conversion, in order to the number that is inserted into " 0 " position between two " 1 " position in the bit sequence is restricted to a defined amount.The number that is inserted into " 0 " position between two " 1 " position is known as " zero run-length ".One " 1 " position in the data bit stream (code sequence) is known as " reversal interval " to the interval (length) between next " 1 " position.The restriction of zero run-length determine the reversal interval of a data bit stream boundary, be maximal value and minimum value.Maximal value is known as " maximum reversal interval k ", and minimum value is known as " minimum reversal interval d ".

(PPM: groove position modulation) be recorded in the situation on the CD media, the position of data bit stream " 1 " records mark corresponding to one, and zero run-length " 0 " is corresponding to a space by mark position record at a data bit stream.At a data bit stream by mark lengths record (PWM: pulse-length modulation) be recorded in the situation on the CD media, when one " 1 " position of data bit stream occurring, switching recording status, that is, is an a record mark or space is recorded on the CD media.In the situation of mark lengths record, reversal interval is corresponding to the length of a record mark or the length in a space.

Therefore, for example, when can the minimum value (such minimum value is called as " mark unit ") of the physical size of the mark that CD media forms in mark position record and mark lengths record be equate time, mark position records the data (3 " 100 " of a data bit stream) that need 3 mark units to record minimum codelength, and the mark lengths record only needs 1 mark unit.

When using the run-length limited code of a minimum reversal interval d=2, the bits number of the per unit length in the mark road of CD media is large in situation about recording than mark position in the situation of mark lengths record.That is, the recording density of mark lengths record will be higher than the recording density of mark position record.

Usually, when a data bit stream that is transformed into modulation code is recorded on the CD media, usually a synchronous mode each specified period at data bit stream is inserted in the data bit stream.When the reading out data bit stream, it is synchronous that such synchronous mode is carried out suitable data.According to a kind of known technology that is used for inserting synchronous mode, a kind of synchronous mode of a non-existent sequence in the modulation code sequence that comprises is inserted into a beginning with zone that is called as the frame zone of specified byte length.

At some data layouts of the CD media that is used for the recent record type that has been implemented, the DVD-RW data layout will briefly be described.

In the DVD-RW data layout, address information is arranged by the pre-pit (pre-pit) in the land face (land) between the adjacent grooves mark road of wherein wanting record data at two.Data by continuous recording on recessed groove track.ECC piece as the least unit of data recording and reproduction comprises a plurality of zones that are called as the Frame zone, and each zone has fixing byte length.The Frame zone comprises one in its synchronizing information zone and data zone that begins to locate to provide.Data recording or the data area that is reproduced in the beginning that is positioned at each ECC piece in the Frame zone begin and stop.Operation for the other record data of an ECC piece after the ECC piece that has recorded therein data is called as " link ".Be called as " linking frames zone " corresponding to beginning and a Frame zone stopping the position of data recording.

Figure 44 has shown the link position of a conventional DVD-RW and near data layout thereof.In DVD-RW, an ECC piece comprises 16 sectors, and a sector comprises 26 frame zones.The least unit of data recording is an ECC piece.The data area DATA that data are recorded in the guiding frame zone (linking frames zone) of the boot sector S0 of an ECC piece begins and stops.Figure 44 begins data recording and the position display that stops is " starting position of data recording ".In example shown in Figure 44, carry out link, so that data are recorded in the 16th byte place termination from the beginning in linking frames zone, data are recorded between the 15th byte of the beginning in linking frames zone and the 17th byte and begin.

Data recording begin and the linking frames zone that stops in, data are with discontinuous mode record.Therefore, the data from link starting position (reference position) to the next frame regional record can not be read, because can not realize accurate bit synchronization.In addition, when the link of low precision so that the length in frame zone when being greater than or less than specified length, perhaps when the chained record of the repetition in the same frame zone makes Signal Degrade in the frame zone, the signal reproduction system that is used for level amplitude limit, PLL etc. reproducing link position and near data the time become unstable.In the worst case, can not reading out data in might the several frames zone after link position.In this case, can not the execution error verification, this might produce a read error.When the bearing accuracy when carrying out link during less than, the possibility that precise information reads increases.Yet, along with the recording density of data increases, be difficult to realize less than one tolerance, be unpractical therefore.

According to the problems referred to above, even target of the present invention provides recording medium, recording method, reproducting method, pen recorder and transcriber that starting position and final position in data recording also can allow stable data recording and reproduction.

Embodiment

After this, with way of example the present invention is described with reference to accompanying drawing.In this instructions, term " beginning " and " end " refer to along the relative position in the information mark road of CD media.At first be recorded or the position of reproducing is called as " beginning " (or beginning of the data that record) of section in section along data in the section in information mark road at one, be recorded at last or the position of reproducing is called as " end " (or end of the data that record) of section in section along data in the section in information mark road at one.Regional A and regional B are arranged along an information mark road and after regional B in regional A executing data record or situation about reproducing, regional A is expressed as with respect to regional B in " back ", regional B is expressed as with respect to regional A in " front ".A zone is not to mean that inevitably these two zones are adjacent one another are with respect to another zone in " back " or the expression in " front ".When regional A with respect to regional B in the back and regional A when adjacent with regional B, it is an adjacent zone after regional B that regional A is expressed as.

In this instructions, a specific region on the information mark road of term " frame zone " expression CD media.In the frame zone, the data of ormal weight and/or the code sequence of ormal weight have been recorded.The data or the code sequence that are recorded in the frame zone are called as one " frame ".In this instructions, term " sector " also represents a specific region on the information mark road of CD media, and comprises above-mentioned a plurality of frames zone.

(example 1)

Fig. 1 has shown the top view according to the CD-R medium (recording medium) 101 of first example of the present invention.On the recording surface of CD media 101, record mark road 102 (posting fields) form in a spiral manner.Record mark road 102 is divided into some data blocks 103.In other words, on the recording surface of CD media 101, data block 103 is pressed the circumferencial direction continuous arrangement, to form information mark road 102.

Fig. 2 has shown the data layout of the data block 103 of CD media 101.As shown in Figure 2, each data block 103 is included in its first frame zone 201 and a plurality of the second frame zones 202 thereafter that begin.The 201 and second frame zone, the first frame zone 202 forms a data block 103.In Fig. 2, the regional back that regional on the left side shows that the right shows.

Like this, the information mark road 102 of CD media 101 is included in a plurality of the second frame zones 202 (being collectively referred to as the first area) and first frame zone 201 (second area) that comprises in the data block.

The first frame zone 201 is included in its first retaining zone PA that begins and the second retaining zone VFO thereafter.

The second frame zone 202 (frame zone) is included in its 3rd retaining zone SY that begins and data area DATA thereafter.The 3rd retaining zone SY is the zone that wherein will record a SY pattern (the second synchronizing code sequence).Data area DATA is the zone that wherein will record at least a portion of the user data that will record in recording medium.In other words, the second frame zone 202 (frame zone) comprises the zone that wherein will record at least a portion of a SY pattern (the second synchronizing code sequence) and user data.

The below will describe the effect in each zone.At first, data area DATA is used for data bit stream that comprises user data of record.Data bit stream comprises one for the parity check code of detection or correction data mistake when reading out data.Parity check code is included in the zone except user data.Data bit stream is not registered as binary data itself, but the modulating system that was complementary by a characteristic with the recording and reconstruction signal of CD media before record carries out conversion.

Here, suppose that data bit stream is a code sequence that is restricted to minimal tour (minimum reversal interval) d and maximum run (maximum reversal interval) k after the conversion, and this code sequence is that data bit stream by will input is divided into and has respectively unit for (piece of position of m * i) then will input every of data and be transformed into one and have unit for (n * i) code sequence obtains.In this case, d and k are natural numbers, satisfy d＜k, and m and n are natural numbers, satisfy m＜n, and i is natural number, satisfy 1≤i≤r.Especially when r=1, this transformation system is called as the fixed length code system, and when r 〉=1 (i can be a plurality of values), this transformation system is called as the variable-length codes system.

When a code sequence during by NRZ (non-return to zero system) format record, the position of code sequence " 1 " corresponding to a record mark, a zero run-length " 0 " is corresponding to a space.In CD media, record mark and space are projection or recessed by pit or are distinguished from each other by the difference in the reflectance that is caused by the phase transformation in the recording layer.When code sequence during by NRZI (Non Return to Zero Inverted) format record, when the data bit stream of " 1 " position occurring, switch recording status, namely be to record a record mark or will record a space.In the situation of mark lengths record, reversal interval is corresponding to the length of a record mark or the length in a space.

The minimum value (such minimum value is called as one " mark unit ") of supposing the size of the mark that can form at the recording layer of CD media equates in NRZ record and NRZI record, then NRZ records the data (3 " 100 " of a data bit stream) that need 3 mark units to record minimum codelength, but the NRZI record only needs a mark unit.Therefore, when using the run-length limited code of a minimum reversal interval d=2, the ratio in the situation of NRZI record of the figure place on the per unit length in the mark road of CD media is large in the situation of NRZ label record.That is, the recording density of NRZI record is higher than the recording density of NRZ record.

In first example of the present invention, the run-length limited code that to adopt a parameter that is used for modulation be d=2, k=10, m=8, n=16 and r=1 is carried out the mark lengths record.In other words, the data bit stream that is recorded among the data area DATA of CD media 101 (Fig. 1) comprises record mark and the record space with minimum length Tmin=3 position and maximum length Tmax=11 position.

The beginning that provides the first retaining zone PA to identify the first frame zone 201, the first retaining zone PA preferably has the absent variable pattern that records in the data bit stream in will being recorded in data area DATA at least.By with one in the DATA of data area absent variable mode record in the first retaining zone PA, when the reading out data bit stream, can easily the first retaining zone PA and data area DATA be made a distinction.

Provide the second retaining zone VFO to come when reading each data block 103, to realize the stable operation of data playback system.Data playback system for example refers to the part and PLL (phaselocked loop) part that is used for extracting from the level sliced data bit synchronization clock that are used for the reproducing signal RF (radio frequency) that reads from data block 103 is carried out the level amplitude limit.In order to realize the stable operation of data playback system, the pattern that is recorded among the second retaining zone VFO preferably satisfies condition 1 to 3 given below.

Enough amplitudes of (condition 1) assurance reproducing signal RF and enough S/N are than (signal to noise ratio (S/N ratio)).

The number of times that (condition 2) record mark/space is switched is enough.

The DSV value (digital summing value) of (condition 3) pattern is as far as possible near 0.

Condition 1 is for suitably obtaining the level sliced data from reproducing signal RF.Too little or its S/N is when too low when the amplitude of reproducing signal RF, because the interference of the noise of data playback system, signal can not be by accurately level amplitude limit or signal are become wrong data by the level amplitude limit.

Condition 2 is for stably obtaining a bit synchronization clock from the level sliced data at a high speed.When the clock frequency/phase was partly locked by PLL in the second retaining zone VFO, the number of times that switches along with the record mark/space was larger, and the information that is used for the frequency/phase comparison can be obtained more continually.Like this, clock frequency/phase place can more promptly be locked.The number of times that switches when the record mark/space too hour can not obtain for frequency/phase information relatively.Consequently, clock frequency/phase place is by slower or more astatically locking.

Condition 3 is used for reproducing signal RF is carried out level amplitude limit stably.In the situation of using a DC feedback system that is typically used as the level limiter system (the DC component of data is carried out the FEEDBACK CONTROL of clipping lever after being used for the level amplitude limit), when the DSV of pattern value obviously fluctuateed or disperses, clipping lever obviously fluctuateed from the center of reproducing signal RF or obviously drifts about (shift).Consequently, can not stablize acquisition level sliced data.Preferably give the DC feedback system near a DSV value of 0 pattern as far as possible.

Provide the 3rd retaining zone SY to identify the beginning in each the second frame zone 202.Be similar to the first retaining zone PA for the beginning in identification the first frame zone 201, be preferably in absent variable pattern in will being recorded at least one data bit stream of data area DATA of record among the 3rd retaining zone SY.By absent variable pattern in the DATA of data area of record in the 3rd retaining zone SY, when the reading out data bit stream, the 3rd retaining zone SY and data area DATA easily can be made a distinction.

Fig. 3 has shown an example of a pattern (PA pattern) that will be recorded among the first retaining zone PA, and this example is desirable especially in first example of the present invention.A feature of PA pattern shown in Figure 3 is that this pattern comprises that length is record mark or the space of 14 channels bits (14T), and this is (Tmax+3) individual channel bit length.As mentioned above, in first example, be recorded in the data bit stream among the DATA of data area maximum mark/space length Tmax is 11 channels bits (11T), the 14T that comprises among this and the first retaining zone PA differs 3.Even the impact owing to the noise that produces at reproduction period occur the edge shifting of 1 channels bits and consequently the 14T mark (or 14T space) in the first retaining zone shorten to 11T mark (or 11T space) among 13 channels bits and the data area DATA when being elongated to 12 channels bits, the difference of 1 channels bits is still arranged between the mark (or space) among the mark in the first retaining zone (or space) and the data area DATA.Like this, with respect to about 1 edge shifting, provide enough mistake tolerance limit to prevent that 11T pattern among the DATA of data area is mistakenly detected as the pattern among the first retaining zone PA.Like this, the PA pattern is used to identify the beginning of follow-up VFO pattern.

In example shown in Figure 3, a 4T space/mark is positioned at adjacent after the 14T mark/space.During data in read block 103, by using (14T+4T) as detecting pattern, the possibility of error-detecting with only use 14T to compare as detecting pattern to be reduced.By with (15T+3T) or (13T+5T) adding detecting pattern to, and be not only (14T+4T), even then occur in the rear end of 14T also avoiding not detecting 14T when an edge drifts about, and the possibility of error-detecting still can keep low as much as possible.

Like this, the PA pattern can easily make a distinction with the VFO pattern of its back or any other pattern that is recorded among the DATA of data area.By detecting transcriber or the pen recorder of PA pattern, become and might determine termination with respect to the data area DATA in the PA pattern data block in front, or the beginning of the data block of the beginning of the second retaining zone VFO of prediction after the PA pattern or the second retaining zone VFO back.The PA pattern that records in the first retaining zone is used to the object lesson of reproducing control or record controls and will be in the back describes in the 6th and the 7th example.The beginning in PA modal representation the first frame zone (second area).

In Fig. 3, the pattern among the first retaining zone PA is shown { 10010010010001000000000000010001} by the NRZ form shfft.By adjacent (14T+4T) add before with situation at modulation code in equally satisfy d=2 and the k=10 (restriction on zero run-length, namely, the sequence (3T+3T+3T+4T) of the run-length restriction number of continuous " 0 " position), form a pattern that altogether has 32 channels bits (that is, 2 bytes).Be positioned at adjacent sequence before 14T and preferably satisfy identical run-length restriction with modulation code, but the present invention is not limited to this point.The pattern of the first retaining zone PA is not limited to a pattern, but can select from a plurality of patterns.For example, prepare have different zero run-lengths a plurality of patterns of (number of continuous " 0 " position) of beginning in pattern.From a kind of pattern of these a plurality of model selections, so that selected pattern satisfies the identical run-length restriction with modulation code when being connected to the zero run-length (last zero run-length) that obtains from the modulation of adjacent byte in front.Perhaps, a plurality of patterns have different DSV values, select a pattern, so that the DSV value after selecting is minimum.DSV value after the selection is the summation of the DSV value of the DSV value of adjacent sequence in selected pattern front and selected pattern.

Fig. 4 has shown an example that will be recorded in a pattern among the second retaining zone VFO (VFO pattern), and this example is desirable especially in first example of the present invention.A feature of the VFO pattern shown in Fig. 4 is that this pattern comprises that 4 channels bits of repetition record mark and space.Pattern shown in Figure 4 satisfies condition 1 to 3 as mentioned above.

Pattern with single length (a single length of) of 4T has guaranteed enough amplitudes (condition 1) of reproducing signal RF.The pattern that maximum mark/space switching times is provided is the pattern with single length (minimum length) of 3 channels bits, but the pattern with single length of 4T is considered to preferable, and its reason is as follows.In the recording and reconstruction characteristic of a CD media that realizes high density recording, has the amplitude of reproducing signal RF of minimum length position usually significantly less than longer mark/space.Therefore, utilize the length of 3 channels bits, may not obtain one by the reproducing signal RF of level amplitude limit stably.Therefore, in order to satisfy condition simultaneously 1 and 2, the pattern with single length of 4T is considered to preferable.Can have DSV=0 owing to have the pattern of the single length of 4T, this pattern also satisfies condition 3.

The pattern among the second retaining zone VFO of being recorded in is not limited to have the pattern of the single length of 4T.Preferably record a pattern that satisfies full terms 1 to 3, but these conditions can be with the priority of the recording and reconstruction characteristic of foundation CD media.For example, in the situation of the CD media of the enough amplitudes (condition 1) that provide reproducing signal RF in record mark or the space of the minimum length that has 3T with, can use one to have the 3T record mark of repetition or the pattern in space.Like this, the number of times of mark/space switching is compared with the pattern of the single length with 4T and can be increased (condition 2).By this way, condition 2 obtains the priority higher than condition 1, and data PLL can lock quickly.Perhaps, even also do not provide in the pattern of the single length that has 4T in the situation of CD media of enough amplitudes of reproducing signal RF, can use 5T record mark with repetition or the pattern in space.In this case, condition 1 obtains higher priority than condition 2; That is, be reduced although the number of times that mark/space is switched is compared with the pattern of the single length with 4T, the precision of data level amplitude limit can be enhanced.

Fig. 5 has shown the illustration pattern that will be recorded among the second retaining zone VFO when Tmin=3 and Tmin=2.In example shown in Figure 5, when Tmin=3, use one to have the 4T record mark of repetition and the pattern in space; And, when Tmin=2, use one to have the 3T record mark of repetition and the pattern in space.

Like this, the pattern with single length of (Tmin+1) individual channels bits provides enough amplitudes of reproducing signal RF, so satisfies condition 1.

When using 8/16 modulating system, Tmin=3 and 1 byte=16 channels bits.Therefore, 4T mark or space are repeated 4 times in each byte.Because the length of the second retaining zone VFO in first example is 91 bytes, so 4T mark or space are repeated (=91 * 4) 364 times.

8/16 modulating system is one and is used for 8 bit binary data are transformed into a system with code word of 16 channels bits.8/16 modulating system is for example described in detail in day disclosure text No.8-31100.In 8/16 modulating system, a plurality of map tables are distributed to (pre-modulation) data before 8 modulation, and switching map table, in order to data transformation before 8 modulation is become a code, so that (post-modulation) code sequence has the least possible low frequency component after the modulation.Switch map table, so that satisfy the condition of minimum reversal interval d=2 and maximum reversal interval k=11, make simultaneously the absolute value of the DSV in the code sequence minimum.

Fig. 6 has shown an example of a pattern (SY pattern) that will be recorded among the 3rd retaining zone SY, and this example is desirable especially in first example of the present invention.A feature of SY pattern shown in Figure 6 is that this pattern comprises that length is record mark or the space of 14 channels bits (14T), and this is (Tmax+3) individual channel bit length.The length of 14T differs 3 with the maximum mark that will be recorded in the data bit stream among the DATA of data area/space length Tmax=11 (11T).Therefore, as top with reference to figure 3 about being recorded in the description of the pattern among the first retaining zone PA, with respect to about 1 edge shifting, provide enough mistake tolerance limit to prevent that 11T pattern among the DATA of data area is mistakenly detected as the pattern among the 3rd retaining zone SY.Like this, the SY pattern is used to the beginning in identification (or expression) the second frame zone 202 (frame zone).

The below will be described in the absolute position (after this being called " address ") in a kind of information mark road 102 for identifying CD media 101 in first example of the present invention.For specified address record data on the CD-R medium, a pen recorder is in the information that needs before the data recording to read on the specified address, and the search data position that will be recorded to.In order to obtain an address information in the zone of record data not also, address information need to be by preformatting.According to an illustrative preformatting technology, address information represents by using at the definite pre-pit of the recessed and bossing of recording surface, and perhaps address information is represented by the tortuous mode of the groove that is formed for forming information mark road 102.

In the present invention, can obtain address information in the CD media 101 with any technology.Unless in this instructions, describe especially, otherwise each data block is given intrinsic address information, and the established part of the address information of each data block by visit information mark road 102 obtains.

Refer again to Fig. 2, will describe a method that is used at CD media 101 (Fig. 1) identifying recording layer with above-mentioned data layout.On CD media 101, adopt data block 103 to come record data as least unit.A series of data are recorded among the second retaining zone VFO in the first frame zone 201 beginning and stop.Here, comprise that first a frame zone 201 in the position of these place's addition record data is called as " linking frames zone ".

When the final position from a series of data recording records additional data, determine the starting position of additional data record and the final position of additional data record, so that always satisfy the S≤E that concerns with following condition.The starting position of additional data record is as S the byte of the second retaining zone VFO in the first frame zone 201 in a linking frames zone (" S " be one less than the rational number of the byte number of the length that represents the second retaining zone VFO).The final position of additional data record is E the byte (" E " be less than the rational number of the byte number of the length that represents the second retaining zone VFO) of the second retaining zone VFO.By determining like this starting position and the final position of additional data record, the part of addition record data does not comprise the zone of any pattern of not record (VFO pattern) that stays therein.Next when not recording any VFO pattern regional when staying, the undesirable possibility that then has playback system accurately not locked.

Difference between S and the E is preferably in the situation of the various fluctuating error factors of considering a drive unit to be determined.Be under zero the perfect condition at fluctuating error, when data recording stops and the byte number that when start-of-record, is provided by (S-E) be recorded in the same area.Therefore, the data of precedence record are rewritten by the data of current record in this zone.Therefore, the byte number that is preferably provided by (S-E) is set to the upper limit of fluctuating error factor or higher.In this case, even when fluctuating error is maximum, also can in the situation that does not stay the zone of not recording any VFO pattern, carry out the additional data record.

When CD media 101 is the rewritable optical disc medium of the formation such as employing phase-change recording material, repeats the additional data record in same position and may cause the deteriorated of recording layer many times.For the deteriorated minimum that makes recording layer and still improve rewriting property (increase data and can be recorded in number of times on the same mark road), when each record data the starting position of data recording and final position can be in a specialized range randomly changing.Under such a case, the length in the first frame zone 201 needs not to be a fixed byte length.Its reason is that the length of the second retaining zone VFO changes according to the starting position of data recording and the variation of final position.How many starting position of data recording and final positions should change and consider that preferably the length, locking required time cycle of playback system, the degradation characteristic of recording layer etc. of the second retaining zone VFO determine.

According to the present invention, the frame zone of beginning additional data record, be that the linking frames zone is the first frame zone 201 that does not comprise data area DATA.Therefore, in addition additional data record neither carry out discontinuously.Therefore, eliminated undesirable possibility that the addition record data were not read and consequently were recorded in a loss of data in the frame zone.Compare reading the mistake tolerance limit and can be significantly increased in the addition record data with in the DATA of data area, carrying out the conventional CD media that links (additional data is recorded among the DATA of data area).Consequently, even at starting position and the final position of data recording, data recording and reproduce and also can stably be carried out.

As understanding from Fig. 2, pen recorder is following at CD media 101 identifying recording layers.At first, start-of-record VFO part 2102 shown in Fig. 2 (for rendering data stably and the first synchronizing code sequence that provides) at first is recorded in the first frame zone 201 (the 3rd zone) on the information mark road 102, then records at least one second frame zone 202.Therefore, the zone at least one the second frame place (first area) is in the back in the first frame zone 201 (the 3rd zone).The first frame zone 201 (the 3rd zone) comprises the zone that wherein will record a start-of-record VFO part 2102 (the first synchronizing code sequence).

The second frame zone 202 comprises for the SY pattern (the second synchronizing code sequence) of the beginning in identification the second frame zone 202 and at least a portion (will be recorded in the data of data area DATA) of the data that will record.In the situation of data corresponding to a plurality of data blocks 1 03 that will be recorded on the CD media 101, provide the first frame zone 201 on the border of two adjacent data blocks 1 03, so that record PA pattern and VFO pattern.When the data recording on CD media 101 stops, a PA pattern (the 3rd synchronizing code sequence) is recorded in after at least one second frame zone 202.Then, a record shown in the record diagram 2 is provided by (record finish) VFO part 2101 (for rendering data stably and the 4th synchronizing code sequence that provides).PA pattern and record are finished VFO part 2101 and are recorded in the first frame zone 201 (second area).This first frame zone 201 (second area) is different from the first frame zone 201 (the 3rd zone) of recording described start-of-record VFO part 2101 when the start-of-record, provides in the back of first area.The first frame zone 201 (second area) comprises that wherein will be recorded the zone that VFO part 2101 (the 4th zone) finished in PA pattern (the 3rd synchronizing code sequence) and record.

In order to change randomly the starting position of addition record, the length of the start-of-record VFO part 2102 as shown in Figure 2 in the VFO pattern (for rendering data stably and the first synchronizing code sequence that provides) can be arranged at random.In order to change randomly the final position of addition record, the length that the record as shown in Figure 2 in the VFO pattern is provided by VFO part 2101 (for rendering data stably and the 4th synchronizing code sequence that provides) can be arranged at random.When the starting position of record or final position during by randomly changing, the length that VFO part 2101 or start-of-record VFO part 2102 finished in record is not indispensable by randomly changing.As mentioned above, the position of record data to be obtained by the address information of preformatting, and no matter data record whether.Therefore, the starting position of record or final position can be with respect to the absolute position on the CD media 101 that obtains by the reproduction address information and by randomly changings.In this case, the record end of finishing VFO part 2101 preferably is located in respect to the beginning of start-of-record VFO part 2102 in the back.

As mentioned above, the starting position of additional data record and final position are provided so that always to satisfy and concern S≤E.Therefore, being recorded in record on the CD media 101 finishes at least a portion of VFO part 2101 (the 4th synchronizing code sequence) and is rewritten by the start-of-record VFO part 2102 (the first synchronizing code sequence) of the VFO pattern that is recorded when carrying out the additional data record.

As mentioned above, in first example of the present invention, the first frame zone and the frame after the first frame zone of being included in beginning as a data block of the least unit of recording and reconstruction are regional.The first frame zone comprises the first retaining zone (PA) and the second retaining zone (VFO).The second frame zone comprises the 3rd retaining zone (SY) and a data area (DATA) that is used for record data.Because such structure, the beginning of data recording (link)/termination can be carried out in the second retaining zone (VFO) in the first frame zone (linking frames zone).Various fluctuating factors in the data recording can be absorbed in the second retaining zone VFO, so always provide stable data recording and reproduction.System overhead is retained as less, for each data block just over a frame.

According to the present invention, will bearing accuracy accurately not be set to less than a channels bits.Therefore, can be with simple structural design drive unit, thus reduce the manufacturing cost of drive unit.

Fig. 7 A shown in first example of the present invention a normal frames zone (namely, the illustration logging mode of starting position the second frame zone 202), Fig. 7 B has shown the illustration logging mode of the starting position in the linking frames zone (that is, the first frame zone 201) in first example of the present invention.Example shown in Fig. 7 A and the 7B is to obtain when the modulation that comes with the run-length limited code with parameter d=1, k=9 and n/m=1.5 for the data area.

In Fig. 7 A, the starting position in normal frames zone refers to the beginning in the second frame zone 202 (Fig. 2) consistent with the data layout of first example of the present invention.Beginning in the second frame zone 202 provides the 3rd retaining zone SY of (that is, 24 channels bits) length that has 2 bytes.Data area DATA provides since the 3rd byte.In the SY pattern of the 3rd retaining zone SY, underlined partial mode " 10000000000001001 " is corresponding to (Tmax+3) pattern (Tmin+1) in the run-length limited code with parameter d=1 and k=9.Consider and being connected of adjacent data area DATA in front, preferably determine " YYYYYY " (left side of Fig. 7 A) in the beginning of SY pattern, in order to satisfy the run-length restriction of d=1 and k=9.

In Fig. 7 B, the starting position in linking frames zone refers to the beginning in the first frame zone 201 consistent with the data layout of first example of the present invention.Beginning in the first frame zone 201 provides the first retaining zone PA of (that is, 24 channels bits) length that has 2 bytes.The second retaining zone VFO provides since the 3rd byte.Underlined partial mode " 10000000000001000001 " in the first retaining zone PA and the second retaining zone VFO is corresponding to (Tmax+3) pattern (Tmin+4) in the run-length limited code with parameter d=1 and k=9.The unique pattern in linking frames zone, namely (Tmax+3) (Tmin+4) pattern and unique pattern in normal frames zone, namely the pass of (Tmax+3) pattern (Tmin+1) is, length from the starting position to the starting position of (Tmax+3) is identical (8 channels bits), and final position (Tmax+3) is identical.

In Fig. 7 B, consider and being connected of adjacent data area DATA in front, preferably determine " YYYYYY " in beginning, in order to satisfy the run-length restriction of d=1 and k=9." YYYYYY " among Fig. 7 B can with Fig. 7 A in " YYYYYY " identical.Even in this case, code distance between PA pattern and the SY pattern still is 3, because adjacent (Tmax+3) pattern afterwards in the SY pattern is (Tmin+1), and adjacent (Tmax+3) pattern afterwards in the PA pattern is (Tmin+4).

Therefore, for example, even SY pattern and PA pattern all have the length of 2 bytes and therefore when (Tmax+3) is included in the length of 2 bytes about eurypalynous pattern can not be formed the time, can be increased by the number of types of the adjacent pattern that makes a distinction in the length of (Tmax+3) pattern afterwards.Like this, the degree of freedom of pattern using increases.

When the degree of freedom of pattern using increases, also might code distance is remained 2 or more situation under increase the number of types of the pattern that can be used as SY pattern or PA pattern, or in the situation of the number of types of the pattern that keeps can be used as SY pattern or PA pattern, code distance is increased to 3 or more on the contrary.

The byte length in the 201 and second frame zone 202, the first frame zone and the number in the second frame zone 202 in each data block 103 will be described in this example.

The byte length in the byte length in the first frame zone 201 and the second frame zone 202 is preferably roughly the same each other, and perhaps one of them regional byte length roughly is the integral multiple of another regional byte length.Roughly be the integral multiple of another byte length by making one byte length in the 201 and second frame zone 202, the first frame zone, the frame interpolation that the data that then might use the same circuits (timing generation circuit etc.) of data recording/reproducing device to come for example to be used for these two frame zones when record data produce and be used for these two frame zones when rendering data.Like this, the scale of data recording/reproducing device can reduce, and therefore cost can reduce.In first example of the present invention, the 201 and second frame zone 202, the first frame zone all has the length of 93 bytes.Perhaps, the byte length in the first frame zone 201 can be about integral multiple of the byte length in the second frame zone 202.

Have in the first frame zone 201 in the situation of length of 93 bytes, pattern shown in Figure 3 is arranged in the first retaining zone PA, pattern shown in Figure 4 is arranged in the second retaining zone VFO, and the first retaining zone PA has the length of 2 bytes, and the second retaining zone VFO has the length of 91 bytes.In this case, the pattern among the second retaining zone VFO comprises 4T record mark or the space of repetition 182 times.

In first example of the present invention, the number in the second frame zone 202 in each data block 103 is 208.This number has determined to insert the frequency in the first frame zone 201 and the data size of data block 103.When this number was larger, the system overhead (redundancy section of form) that is caused by the first frame zone 201 that does not have data area DATA was less, had therefore obtained to increase the effect of the memory capacity of CD media 101.Yet such big figure is disadvantageous when processing undersized data, because the data size of data block 103 is increased.

As shown in Figure 2, an ECC piece comprises 4 continuous data blocks 103.In this case, the number in the second frame zone 202 of each ECC piece is 208 * 4=832.The ECC piece is defined as the coding units of an error check code.For example, adopting known Reed Solomon code to form two-dimensionally in the situation as one of an error check code known product code, the ECC piece is the unit of product code.When the 3rd retaining zone SY had the length of 2 bytes, the overall dimensions of all data area DATA of each ECC piece was 91 * 832=75712 byte.In first example of the present invention, 65536 bytes in 75712 bytes are used to user data, and remaining byte is assigned to redundant data, such as error checking and correction, block identification ID etc.

By forming an ECC piece that forms the error check code of integer number of data blocks, wherein each data block is the least unit of a series of data recording, and the effect that helps the management of record data in drive unit (pen recorder or transcriber) is provided.In first example of the present invention, 1 ECC piece=4 data block, but the present invention is not limited to this point.Even the number of the data block that comprises in an ECC piece also can provide similar effect when changing.For example, 1 ECC piece can comprise a data block.Yet in first example, the number of the data block that comprises in an ECC piece must have a upper limit, because the guiding frame zone of each data block is the first frame zone 201 (that is, redundant data) that does not comprise data area DATA.Consider error checking and correction performance and the system overhead of drive unit, the number of the data block that preferably will comprise in an ECC piece is defined as a value that is suitable for the use of optical disc apparatus 101, the performance of drive unit etc.

Irrelevant with the second frame zone 202, the pattern that is recorded among the 3rd retaining zone SY does not need identical.For example, the second frame zone 202 after the first frame in each data block 103 zone 201 can have one and is different from the AD HOC that is recorded in the pattern in other the second frame zones 202.Like this, AD HOC above-mentioned can be identified by drive unit.Therefore, the first data area DATA in each data block 103 can be detected with degree of precision, and this has improved the reliability of drive unit.In second following example, the SY pattern that is recorded in one beginning in a plurality of the second frame zones 202 is different from the SY pattern of the beginning that is recorded in other the second frame zones 202.

In first example, the first frame zone (first area and the 3rd zone) comprises the first retaining zone PA and the second retaining zone VFO, but also can comprise other synchronizing code sequence or data bit streams.

(example 2)

Fig. 8 has shown the top view according to the CD-R medium (recording medium) 3101 of second example of the present invention.As shown in Figure 8, on a recording surface of CD media 3101, form in a spiral manner record mark road 3102 (posting fields).Record mark road 3102 is divided into some data blocks 301.In other words, on the recording surface of CD media 3101, data block 301 in a circumferential direction continuous arrangement to form information mark road 3102.

Fig. 9 has shown an example of the data layout of the CD media 3103 in second example of the present invention.In Fig. 9, be denoted by the same reference numerals with top those identical elements of describing with reference to figure 2, will be not described in detail here.In Fig. 9, the back in the zone shown in the regional on the left side shown in the right.

As shown in Figure 9, each data block 301 comprises 201 and 8 sectors 3103, the first frame zone.Four data blocks 301 form an ECC piece 302.Therefore, an ECC piece comprises 32 sectors.

A plurality of the second frame zones that comprise in each data block 301 are grouped into a plurality of sectors 3103, and each sector comprises 26 the second frame zones.

Each sector 3103 (the 4th zone) comprises 26 the second frame zones.Each frame zone has the length of 93 bytes.The frame zone that is positioned at the beginning of sector 3103 represents by label F0,25 remaining frame zones by label F1, F2 ... F24 and F25 represent.

Frame zone F0 is included in its retaining zone SY0 that begins (the 3rd retaining zone) and data area DATA subsequently.Frame zone F1 is included in respectively its retaining zone SY that begins (the 3rd retaining zone) and data area DATA subsequently to F25.Retaining zone SY0 and retaining zone SY have the length of 2 bytes.Therefore, the length of each among frame zone F0 and frame zone F1 all data area DATA in the F25 is 91 bytes.

The sum of the byte of all the data area DATA in each sector 3103 is 91 * 26=2366 byte.Be recorded in the length that user data in each sector has 2048 bytes, such as the address information of the record position that is used for recognition data, for detection of or the redundant data of the parity check code of check for errors etc. have the length of 318 bytes.User data and redundant data are 2366 bytes altogether.

The data bit stream that is recorded among the DATA of data area is not registered as binary data itself, but carries out conversion by the modulating system of characteristic of the recording and reconstruction signal of a coupling CD media before being recorded.Here supposition adopts 8/16 modulating system to carry out the NRZI record.The data bit stream that is recorded among each data area DATA has the length of 91 * 16=1456 channels bits, and comprises record mark or the space of minimum length Tmin with 3 and 11 s' maximum length Tmax.

Provide retaining zone SY0 to come for the beginning of identifying frame zone F0, and retaining zone SY0 preferably have the absent variable pattern that records at least one data bit stream in will being recorded in data area DATA.By absent variable pattern in the DATA of data area of record in retaining zone SY0, retaining zone SY0 can easily make a distinction with data area DATA when the reading out data bit stream.

Provide each retaining zone SY to come the beginning to each the second frame of F25 for identification the second frame zone F1.The same with the retaining zone SY0 in the F0 of frame zone, each retaining zone SY preferably has the absent variable pattern that records at least one data bit stream in will being recorded in data area DATA.By absent variable pattern in the DATA of data area of record in retaining zone SY, retaining zone SY can easily make a distinction with data area DATA when the reading out data bit stream.After this, the pattern that is recorded among retaining zone SY or the retaining zone SY0 is also referred to as one " synchronizing code sequence ".

Figure 10 has shown each a example of the synchronizing code sequence that begins to locate that is arranged in 26 frame zones that sector 3103 (Fig. 9) comprises.The synchronizing code sequence is classified into two types, SY0 pattern and SY pattern.The SY pattern is arranged in second to the 26th frame zone.

Figure 11 has shown an example that preferably is used as a pattern of synchronizing code sequence in second example of the present invention.Pattern shown in Figure 11 comprises record mark or a space with length of 14 channels bits (14T), and wherein 14T is (Tmax+3) individual channel bit length.In second example, as mentioned above, be recorded in the data bit stream among the DATA of data area maximum mark/space length Tmax is 11 channels bits (11T), the 14T that comprises in this and the synchronizing code sequence differs 3.Even the impact owing to the noise that produces at reproduction period occur the edge shifting of 1 channels bits and consequently the 14T mark (or 14T space) in the synchronizing code sequence shorten to 11T mark (or 11T space) among 13 channels bits and the data area DATA when being elongated to 12 channels bits, the difference of 1 channels bits is still arranged between the mark (or space) among the mark in the synchronizing code sequence (or space) and the data area DATA.Like this, with respect to about 1 edge shifting, provide enough mistake tolerance limit to prevent that 11T pattern among the DATA of data area is mistakenly detected as the pattern in the synchronizing code sequence.

Provide one 2 therebetween or more code distance for SY0 pattern and SY pattern being distinguished from each other out, being preferably in.Here, code distance refers to the figure place that differs between two data bit streams.In the situation of NRZ record, code distance is provided by the data bit stream in the NRZ representation.In the situation of NRZI record, code distance is provided by the data bit stream in the NRZI representation.When the code distance between SY0 pattern and the SY pattern is equal to or greater than 2, even when 1 drift errors occurring in the process that reads a pattern, a pattern can be identified as another pattern mistakenly yet.

When code distance was equal to or greater than 3, recognition performance was further improved.For example, adopt code distance 2, when SY0 pattern and SY pattern during in one of the direction drift that approaches each other, these two patterns become identical, can not be distinguished from each other out.On the contrary, adopt to be equal to or greater than 3 code distance, when SY0 pattern and SY pattern during in one of the direction drift that approaches each other, a difference that is equal to or greater than is arranged still, these two patterns can be distinguished from each other out.Therefore, SY0 pattern and SY pattern always can be distinguished from each other out, and keep simultaneously the fault-tolerant of 1 faults.As long as the code distance between SY0 pattern and each the SY pattern is equal to or greater than 2, can use polytype SY pattern.

Figure 12 has shown SY0 pattern in second example of the present invention and an object lesson of SY pattern.SY0 pattern and SY pattern all have the length (that is, 32 channels bits) of 2 bytes and all comprise a public unique pattern (14T+4T).This equipment mates the length of these two patterns also so that these two patterns comprise that all an advantage of a public unique pattern is the equipment that can simplify for detection of pattern, because can comprise a public mode detecting system that is used for these two patterns.

Unique pattern is corresponding to (Tmax+3) pattern (Tmin+1) in 8/16 modulating system.Be positioned adjacent mark (or space) having (Tmax+3) position afterwards by the space (or mark) that will have (Tmin+1) position, improved the detection performance of pattern itself.In other words, by using (14T+4T) as detecting pattern, compare the possibility that can reduce error-detecting as detecting pattern with only using 14T during data in read block 3103.By with (15T+3T) or (13T+5T) adding detecting pattern to, and be not only (14T+4T), even when an edge shifting appears at the rear end of 14T, also can avoid not detecting 14T, and the possibility of error-detecting still is held as far as possible little.

Figure 12 has shown the pattern of the Four types that can be used as the SY0 pattern and can be used as the pattern of the Four types of SY pattern (two types are used for 2, two types of state 1 and states and are used for state 3 and state 4).Here, state 1 to 4 shows which the index information in a plurality of map tables that will select 8/16 modulating system.The pattern that is used for state 1 and state 2 has a feature, and namely the zero run-length in MSB one side (left side of Figure 12) is 2 or 3.The pattern that is used for state 3 and state 4 has a feature, and namely the zero run-length in MSB one side (left side of Figure 12) is 0; That is, MSB is with the beginning of " 1 " position.

The below will describe and how to make one's options from four SY0 patterns.When adjacent before retaining zone SY0 modulation result, when namely the NextState of last data byte among the data area DATA in the F25 of frame zone after modulated is 1 or 2, selection mode 1 and state 2.Otherwise, selection mode 3 and state 4.Like this, zero run-length can be in a specialized range of the tie point of last byte of frame zone F25 and SY0 pattern (in 2 to 10 the scope).About the SY pattern, carry out in a similar fashion and select.

Then, will describe How to choose first selects code sequence (being presented at left one side of something of Figure 12) or second to select code sequence (being presented at right one side of something of Figure 12).Select in the code sequence first, CDS (code word numeral summation) be one on the occasion of; Select in the code sequence second, CDS is a negative value.Here, CDS is the value that all the summation in the code sequence (pattern) that obtains by the NRZI conversion of calculating by code sequence obtains, and supposes that MSB is 1.Position " 1 " is made as+1 and position " 0 " is made as-1 carries out summation.That is, adjacent DSV value and the summation of the CDS of code sequence in front is the DSV value of having selected after this code sequence.Because first selects the symbol and second of the CDS of code sequence to select the symbol of code sequence opposite each other, thus select them one of them so that the value of DSV is more approaching zero.Consequently, the value of DSV can be controlled effectively.

The below will describe the most significant feature of the pattern among Figure 12.The most significant feature is to can be used as the pattern of Four types of SY0 pattern and the code distance that can be used as between the pattern of Four types of SY pattern all is equal to or greater than 2 (in the NRZI representations).

For example, check the underlined pattern " 10010001000001000000000000010001 " in the pattern can be used as the SY0 pattern and can be used as code distance between each of four kinds of patterns of SY pattern.Code distance between the pattern " 00010000000001000000000000010001 " in above-mentioned underlined pattern and the NRZI representation is 7.This code distance is by relatively by to carrying out pattern " 11100001111110... " that the NRZI conversion obtains and finding by the latter's pattern that begins with position " 0 " being carried out the pattern " 00011111111110... " that the NRZI conversion obtains with the former model of position " 1 " beginning.

Equally, code distance between above-mentioned underlined pattern and the pattern " 00100000001001000000000000010001 " is 4, code distance between above-mentioned underlined pattern and the pattern " 10001000010001000000000000010001 " is 3, and the code distance between above-mentioned underlined pattern and the pattern " 10001000000001000000000000010001 " is 6.Therefore, all code distances all satisfy 2 the condition that is equal to or greater than.Remain by all code distances with SY0 pattern and SY pattern and to be equal to or greater than 2, even when a mistake such as a drift etc. occurring, also can reduce the possibility of the wrong identification of two patterns.By only the guiding frame of sector 3103 zone F0 and the regional F1 of other frames being differentiated to F25, can easily detect the beginning of sector 3103.Being recorded in each frame zone F1 can be to comprise that a pattern with (Tmax+3) position and one have the pattern of (Tmin+1) position and satisfies in a plurality of patterns that code distance with SY0 is equal to or greater than 2 condition any one to the pattern among the retaining zone SY of the beginning of F25.

Figure 13 has schematically shown the different code distance between the type of synchronizing code sequence (pattern).Figure 13 has shown the relation between synchronizing code sequence SY0 (SY0 pattern) and the synchronizing code sequence SY (SY pattern).When the code distance when therebetween only had 1, occurring 1 faults when reading the SY0 pattern, will to cause the SY0 pattern to be read as identical with the SY pattern.Therefore, when 1 faults occurring, even determine that by complete coupling (only have when whole pattern is mated each other fully just definite two definite technology that pattern is mutually the same) can not determine the type of the pattern that reads.

When the code distance between SY0 pattern and the SY pattern is 2,1 faults in a pattern, occurs and can not cause two patterns mutually the same.Even when in these two patterns, all 1 faults occurring, as long as use fully coupling to determine, also can determine the type of the pattern that reads.Therefore, employing fully coupling is definite, and determining of the type of synchronizing code sequence is possible.

When the code distance between SY0 pattern and the SY pattern was 3, also still to make code distance be 1 even 1 faults all occurs in these two patterns.Therefore, even when using the definite technology that allows 1 faults, also can determine the type of read mode.When using that coupling is determined fully, even can allow 2 faults.

From top description, be appreciated that the code distance that uses between the type be equal to or greater than 3 synchronizing code sequence is 2 compare with using code distance, reliability is higher.

Figure 14 has shown the illustration inner structure of frame zone F0.In example shown in Figure 9, data area DATA only is positioned at adjacent after retaining zone SY0.On the contrary, in example shown in Figure 14, in adjacent Data Position identified areas data ID and the error checking and correction zone parity checking that after retaining zone SY0, provides for the Data Position identified areas.Because such structure, can be after detecting the SY0 pattern that is recorded among the retaining zone SY0 content of reading out data position identified areas data ID immediately.The content of Data Position identified areas data ID for example can comprise a sector number.In this case, the position of sector can only be determined by reading out data position identified areas data ID.Therefore, the position of sector can only be identified by detecting the SY0 pattern, and this allows transcriber easily and promptly to detect the sector.

Figure 15 has shown the object lesson of SY0 pattern, SY pattern and PA pattern in second example of the present invention.SY0 pattern and SY pattern and top described identical with reference to Figure 12 are not described in detail here.

To determine the PA pattern with top with reference to the described similar mode of mode for SY0 pattern and SY pattern of Figure 12.The PA pattern has the length of 2 bytes (that is, 32 channels bits).For consistent with 8/16 modulating system, state control (be used for the pattern of state 1 and state 2 or be used for the selection of the pattern of state 3 and state 4) is possible, and DSV control (selection of pattern, the symbol of reciprocal CDS, that is, plus or minus) also be possible.DSV control suppresses the DC component of the rear data bit stream of modulation.

SY0 pattern, SY pattern and PA pattern all comprise a public unique pattern (14T+4T).An advantage that has identical figure place and comprise these three patterns of a public unique pattern is that the equipment for detection of pattern can be simplified, because this equipment can comprise a commonality schemata detection system that is used for these three patterns.

The pattern of the Four types that the most significant feature of the pattern among Figure 15 is the pattern that can be used as the Four types of SY0 pattern, can be used as the SY pattern and the code distance that can be used as between the pattern of Four types of PA pattern all are equal to or greater than 2 (in the NRZI representations).

For example, inspection be can be used as the underlined pattern " 00000010010001000000000000010001 " in the pattern of PA pattern and can be used as each in four patterns of SY0 pattern and can be used as code distance between in four patterns of SY pattern each.Code distance between the SY0 pattern " 00100100001001000000000000010001 " in above-mentioned underlined pattern and the NRZI representation is 4.This code distance is by relatively by to carrying out pattern " 11111100011110... " that the NRZI conversion obtains and finding by the latter's pattern that begins with position " 0 " being carried out the pattern " 00111000001110... " that the NRZI conversion obtains with the former model of position " 1 " beginning.

Equally, code distance between above-mentioned underlined pattern and the SY0 pattern " 00010000100001000000000000010001 " is 4, code distance between above-mentioned underlined pattern and the SY0 pattern " 10010001000001000000000000010001 " is 5, and the code distance between above-mentioned underlined pattern and the SY0 pattern " 10000000010001000000000000010001 " is 6.Therefore, all code distances all satisfy 2 the condition that is equal to or greater than.Code distance between above-mentioned underlined pattern and the SY pattern " 00010000000001000000000000010001 " is 6, code distance between above-mentioned underlined pattern and the SY pattern " 00100000001001000000000000010001 " is 5, code distance between above-mentioned underlined pattern and the SY pattern " 10001000010001000000000000010001 " is 3, and the code distance between above-mentioned underlined pattern and the SY pattern " 10001000000001000000000000010001 " is 7.Therefore, all code distances all satisfy 2 the condition that is equal to or greater than.

The object lesson of SY0 pattern, SY pattern and PA pattern when the run length of data bit stream is limited to Tmin=3 and Tmax=11 after modulation has been described in the above.Below, the object lesson of SY0 pattern, SY pattern and PA pattern when Tmin=2 and the Tmax=8 is described with reference to Figure 16.The pattern that the following describes is for example being used so-called (1-7) modulating system, especially desirable when namely having the run-length limited code system changeover data area DATA of parameter d=1, k=7, m=2 and n=3.

As mentioned above, Figure 16 has shown the object lesson of SY0 pattern, SY pattern and PA pattern desirable in second example of the present invention.Pattern shown in Figure 16 all has the feature of the pattern " 100000000001001 " that comprises underlined NRZ representation.Commonality schemata is corresponding to (Tmax+3) pattern (Tmin+1) of (1-7) modulating system.The advantage and top describe in first example the same of so public unique pattern are provided.

In example shown in Figure 16, provide the Four types that can be used as the SY0 pattern pattern, can be used as the SY pattern Four types pattern and can be used as the pattern of the Four types of PA pattern (two types just be used for that the LSB of the coded word of front is the situation of " 0 ", the situation of namely not reversing at LSB by the NRZI representation; Two types just are used for that the LSB of the coded word of front is the situation of " 1 ", and the situation of counter-rotating namely occurs at LSB by the NRZI representation).Based on the classification of the LSB of the coded word of front just corresponding to the Tmin in (1-7) modulating system.In other words, be 0 or being equal to or greater than 1 carries out above-mentioned selection by the zero run-length according to LSB one side, when the data of front just were modulated, run-length restriction can realize in the coupling part.

First select code sequence (being presented at left one side of something of Figure 16) have on the occasion of CDS, the second CDS that selects code sequence (being presented at right one side of something of Figure 16) to have negative value.Like this, as top described with reference to Figure 15, the DSV value can be effectively controlled.

The pattern of the Four types that the most significant feature of the pattern among Figure 16 is the pattern that can be used as the Four types of SY0 pattern, can be used as the SY pattern and the code distance that can be used as between the pattern of Four types of PA pattern all are equal to or greater than 2 (in the NRZI representations).

For example, inspection be can be used as the upper left pattern " 010000000100000000001001 " in the pattern of SY0 pattern and can be used as each in four patterns of SY pattern and can be used as code distance between in four patterns of PA pattern each.Code distance between the SY pattern " 010001010100000000001001 " in above-mentioned underlined pattern and the NRZI representation is 2.This code distance is by relatively by to carrying out pattern " 1000000001... " that the NRZI conversion obtains and finding by the latter's pattern that begins with position " 1 " being carried out the pattern " 1000011001... " that the NRZI conversion obtains with the former model of position " 1 " beginning.

Equally, code distance between above-mentioned underlined pattern and the SY pattern " 010010000100000000001001 " is 4, code distance between above-mentioned underlined pattern and the SY pattern " 101010000100000000001001 " is 3, and the code distance between above-mentioned underlined pattern and the SY pattern " 100010000100000000001001 " is 3.Therefore, all code distances all satisfy 2 the condition that is equal to or greater than.Code distance between above-mentioned underlined pattern and the PA pattern " 010101000100000000001001 " is 2, code distance between above-mentioned underlined pattern and the PA pattern " 010101010100000000001001 " is 5, code distance between above-mentioned underlined pattern and the PA pattern " 100010100100000000001001 " is 3, and the code distance between above-mentioned underlined pattern and the PA pattern " 101010100100000000001001 " is 3.Therefore, all code distances all satisfy 2 the condition that is equal to or greater than.

By so that the code distance relevant with the PA pattern with SY0 pattern, SY pattern keeps being equal to or greater than 2, even when a mistake such as a drift etc. occurs, the possibility of the wrong identification of three patterns also can reduce.Therefore, the guiding frame of sector 3103 zone F0 can come to the F25 difference with other frame zones F1, and this helps to detect the beginning of sector 3103.

Can come with other frame zone differences definitely in the first frame zone 201 corresponding to the linking frames zone, this helps to detect link position.By detecting link position, the uncontinuity of the data that caused by link can easily suitably be processed.The processing of being carried out by pen recorder the below will be described in the additional data record in the 6th and the 7th example during and the processing of in the linking frames zone, being carried out by transcriber.

Figure 17 has shown each another example of the synchronizing code sequence that begins to locate that is arranged in 26 frame zones that sector 3103 (Fig. 9) comprises.In example shown in Figure 17, the SY0 pattern is arranged in the guiding frame zone of sector 3103.{ SY1SY1SY2SY1SY1SY2SY1...SY1SY2SY1} sequentially is arranged in follow-up frame zone from the subsequent frame zone beginning that is close to.In this example, a SY2 pattern is with one frequency localization in three successive frame zones except guiding frame zone.

Figure 18 A has shown that to 18D the order that is recorded on the CD media according to the synchronizing code sequence arranges the example that will be recorded in the synchronizing code sequence in the second included in sector frame zone.Figure 18 A is corresponding to the arrangement of the top synchronizing code sequence of describing with reference to Figure 10.In the example shown in Figure 18 A, the synchronizing code sequence (SY0 pattern) that only is arranged in guiding frame zone is to be dissimilar with the synchronizing code sequence that is positioned at other frame zones (SY pattern).Therefore, when because defective of the recording surface of CD media etc. and when in a position of sector a vertical shift (slip) occuring, be difficult to determine the position in current frame zone of reading, until detect next SY0 pattern.

In the arrangement of Mode S Y0, the SY1 of the use three types of Figure 18 B and SY2, arrangement by checking minimum three successive frame zones (for example, SY1SY2SY1}), can determine to have occured a forward frame skew or a backward vertical shift has occured.{ detect immediately the SY0 pattern after the arrangement of SY1SY2SY1}, so can be than the beginning that detects more reliably the sector in the situation that only detects the SY0 pattern owing to be expected at.

Effective arrangement of the Mode S Y0 of this three types, SY1 and SY2 is not limited to above-mentioned arrangement.Adjacent the arrangement after the SY0 pattern can be shown in Figure 18 C { SY1SY2SY1SY1SY2...}, or { SY2SY1SY1SY2SY1...}.This can provide and aforesaid similar effect.Perhaps, a circulation can comprise four the pattern that is equal to or greater than.Figure 18 D has shown such example, i.e. { SY1SY1SY1SY2SY1SY1 SY1SY2...}.

The aforesaid way of the arrangement of the synchronizing code sequence in the second frame zone can be summarized as follows.The SY2 pattern is positioned at the beginning in M frame zone of sector, and the SY1 pattern is positioned at each the beginning in other frame zones.Here, " M " satisfies M=J * K+L, wherein M is one and is equal to or less than N (N is the sum in the second frame zone of comprising in a sector, be one and be equal to or greater than 3 integer) natural number, J and L are that (J is one and is equal to or greater than 2 integer constant, L is a natural number that is equal to or less than J), K is one and is equal to or greater than 0 integer.When pattern is located by this way, by checking the arrangement in minimum J successive frame zone, can determine to have occured until (J-1) skew of individual forward frame still occured until (J-1) individual backward vertical shift.

Example shown in Figure 18 B and the 18C is corresponding to the situation of N=26, J=3 and K=0 to 8 wherein.

When with four patterns (four frame zones) be cycled to repeat the pattern of three types the time, by checking the arrangement in minimum four successive frame zones, can determine until 2 vertical shifts.Along with the number in the frame zone that comprises in the circulation increases to 5,6..., the number of the vertical shift that can detect also increases.Yet, along with the number in the frame zone that comprises in the circulation increases, need the number in the successive frame zone of checked arrangement also to increase.Like this, spent the definite vertical shift of longer time cycle.In the too much situation of the figure place of a mistake, be difficult to check this arrangement, and may have undesirably damaged the reliability of transcriber.Therefore, will be usually the circulation in frame zone be defined as optimum according to desired other of the maximum number of the vertical shift that should be detected or transcriber.

Figure 19 A has shown that to 19C the order that is recorded on the CD media according to the synchronizing code sequence arranges other examples that will be recorded in the synchronizing code sequence in the second frame zone that comprises in the sector.Figure 19 A is identical with Figure 18 A, and only the cause for reference provides.In Figure 19 B, the synchronizing code sequence (SY2 pattern) that only is arranged in last frame zone is to be dissimilar with the synchronizing code sequence that is arranged in other frame zones (SY1 pattern).In this case, { arrangement of SY1SY2SY1} is compared with the situation that only detects the SY0 pattern, and the reliability that detects the beginning of sector can be enhanced by detecting three continuous modes.Perhaps, shown in Figure 19 C, different synchronizing code sequence (SY2 pattern) can be arranged in last a plurality of frames zone of sector rather than last frame zone of sector.

Figure 20 has shown that the order that is recorded on the CD media according to the synchronizing code sequence arranges another example that will be recorded in the synchronizing code sequence in the second frame zone that comprises in the sector.In example shown in Figure 20, the synchronizing code sequence (SY2 pattern) that is arranged in an intermediate frame zone of sector is to be dissimilar with the synchronizing code sequence that is arranged in other frame zones (SY1 pattern).For example, when the SY2 pattern is arranged in the 14th frame zone of sector, the pattern (SY2 pattern) that per 1/2 sector (13 frame zones) record is dissimilar with other patterns (SY1 pattern).Like this, can detect faster and more reliably the beginning of sector.In the situation of using two types Mode S Y0 and SY1, need to detect the SY0 patterns to several contiguous sectors, in order to detect the beginning of sector with higher reliability.In the situation of the Mode S Y0 that arranges as shown in figure 20 three types, SY1 and SY2, only by detect per 13 frame zones { arrangement of SY0SY2} just can be with the beginning of higher reliability detection sector.

As mentioned above, by the synchronizing code sequence of suitably arranging three types in a plurality of frames zone that in a sector, comprises, compare with using two types synchronizing code sequence, can improve the reliability of the beginning that detects the sector.

When using the synchronizing code sequence of three types, be set to be equal to or greater than 2 (or being equal to or greater than 3) by all code distances and obtain higher reliability.As long as other patterns of two types of SY0 pattern distance are a code distance that is equal to or greater than 2 (or 3), just obtained to improve the effect of the reliability of the beginning that detects the sector.

The below will be described in the example of the arrangement in the situation of the synchronizing code sequence of using Four types.

Figure 21 has shown each another example of synchronizing code sequence of beginning that is arranged in 26 frame zones that sector 3103 (Fig. 9) comprises.In example shown in Figure 21, a sector comprises 26 frame zones.Synchronizing code sequence SY0, SY1, SY2 and the SY3 of Four types is arranged in this 26 frame zones.The SY0 pattern is arranged in the first frame zone.{ SY1SY2SY3SY1SY2SY3...SY1SY2SY3SY1} sequentially is arranged in the frame zone of back since the second frame zone.In this example, except guiding frame zone, SY2 pattern and SY3 pattern are respectively with one frequency localization in three successive frame zones.

Figure 22 A has shown that to 22C the order that is recorded on the CD media according to the synchronizing code sequence arranges the example that will be recorded in the synchronizing code sequence in the second frame zone that comprises in the sector when with Mode S Y0, the SY1 of Four types, SY2 and SY3.Figure 22 A is corresponding to the arrangement of the top synchronizing code sequence of describing with reference to Figure 21.In the example shown in Figure 22 A, even when a vertical shift appears in a position in the sector, by check minimum three successive frame zones, for example { arrangement of SY1SY2SY3} also can detect and the skew of forward direction occurred or a backward skew occurred.Because expection SY0 pattern is detected as adjacent { after the arrangement of SY1SY2SY1}, so can detect more reliably than the situation that only detects the SY0 pattern beginning of sector.

Perhaps, shown in Figure 22 B, for the detection of the SY0 pattern that guarantees next sector, only the synchronizing code sequence (SY3 pattern) in last frame zone of sector is dissimilar with the synchronizing code sequence that is arranged in other frame zones.In this case, for example, { arrangement of SY2SY3SY0} is compared with the situation that only detects the SY0 pattern, can improve the reliability of the beginning that detects the sector by detecting.About other frames zone, as top described to 18D with reference to figure 18B, { can detect during the arrangement of SY1SY1SY2} even a locational vertical shift in the sector in repetition.

Again or, shown in Figure 22 C, it can be dissimilar with the synchronizing code sequence that is arranged in other frame zones only having the synchronizing code sequence (SY3 pattern) in the intermediate frame zone of sector.In other frame zones, can repeat { the arrangement of SY1SY1SY2}.In this case, by checking the arrangement that comprises the SY3 pattern in per 1/2 sector, can improve the reliability of the beginning that detects the sector.In addition, can improve the reliability that detects a vertical shift.

As mentioned above, by the synchronizing code sequence of suitably arranging Four types in a plurality of frames zone that in a sector, comprises, except the effect that provides by the synchronizing code sequence of using three types, can also improve frame synchronization/sector net synchronization capability.

When using the synchronizing code sequence of Four types, be set to be equal to or greater than 2 (or being equal to or greater than 3) by all code distances, obtained higher reliability.As long as the pattern of other three types of SY0 pattern distance for being equal to or greater than the code distance of 2 (or 3), just can obtain to improve the effect of reliability of the beginning of detection sector.

As mentioned above, in the foundation CD media 3101 of second example of the present invention, the first data unit (sector) comprises a guiding frame zone (F0) and is positioned at least one frame regional (F1 is to F25) of (F0) back, guiding frame zone.Guiding frame zone (F0) comprises that one will be recorded the zone of SY0 pattern and the data area (DATA) that is wanted user data.In at least one frame zone (F1 is to F25) each comprises that one will be recorded the zone of SY pattern and the data area (DATA) that is wanted user data.The SY0 pattern is all identical on length with the SY pattern, and is set to have betwixt and is equal to or greater than 2 code distance.

More specifically, each the second synchronizing code sequence that SY pattern (the second synchronizing code sequence) distance that is arranged in the guiding frame zone F0 in the individual frame of 26 (defined amounts) zone (F0 is to F25) is arranged in other frames regional (F1 is to F25) is to be equal to or greater than 2 code distance.

Because such structure can easily detect the SY0 pattern during data reproduction, therefore can easily detect fast the beginning of each the first data unit (sector).

Being equal to or greater than at the code distance between SY0 pattern and the SY pattern in 3 the situation, is that 2 situation is compared with code distance, on the contrary further reduced with SY0 pattern error-detecting be the SY pattern or possibility.SY0 pattern and SY1 pattern can be distinguished from each other out, and still allow 1 mistake simultaneously.Therefore, can further improve the reliability of the beginning of the synchronous stability in frame synchronization/sector and detection the first data unit (sector).Like this, can improve the reliability of transcriber.

By synchronizing code sequence (SY1 and the SY2 with at least two types, or SY1, SY2 and SY3) be placed on and follow after guiding frame zone at least one frame zone, can obtain the information about the arrangement of the synchronizing code sequence in the successive frame zone of the regional F1 of frame in the F25.This information can be used for being expected at the appearance of SY0 pattern of next the first data unit (sector) or detection and correction because the vertical shift that PLL non-locking partly causes.

Preferably the code distance between the SY0 pattern in the guiding frame zone of the first data unit (sector) and other synchronizing code sequences (SY1 and SY2, or SY1, SY2 and SY3) is set to be equal to or greater than 2 (or 3).Preferable, the code distance between all dissimilar synchronizing code sequences is set to be equal to or greater than 2 (or 3).By this way, can further improve the reliability of the beginning that detects a sector and the reliability of the frame synchronization that caused by the faults such as non-locking such as the PLL part.

First data unit (sector) of defined amount has formed the second data unit (data block).The first frame zone 201 is arranged in each second data unit (data block).The PA pattern is positioned at the beginning in the first frame zone 201.The SY0 pattern is all identical on bit length with the SY1 pattern, and its position is to be equal to or greater than each other 2 code distance apart.Because such structure can easily detect the PA pattern, and can easily detect fast the beginning of each the second data unit (data block) during data reproduction.The starting position of a series of information recording /s (link) and final position are arranged in the first frame zone 201 (linking frames zone).Therefore, can improve the reliability of link (addition record), and can stablize executive logging at high speed link position and near the data reproduction of information.

In second example, the first frame zone (first area and the 3rd zone) comprises the first retaining zone PA and the second retaining zone VFO, but can comprise other synchronizing code sequence or data bit streams.In above-mentioned preferred example, be recorded in synchronous mode PA in the first frame zone, will be recorded in the synchronous mode SY0 in the second frame zone of the beginning that is arranged in each sector and the synchronous mode SY that will be recorded in the second frame zone except the second frame zone of the beginning that is arranged in each sector is set to have identical length, and also have therebetween and be equal to or greater than 2 code distance.The present invention is not limited to this point.

(example 3)

Figure 23 has shown the top view according to the CD-R medium 401 of the 3rd example of the present invention.On a recording surface of CD media 401, form in a spiral manner record mark road 402.To record mark road 402 and be divided into some data blocks 403.In other words, on the recording surface of CD media 401, in circumferencial direction continuous arrangement data block 403 to form information mark road 402.

Figure 24 has shown the data layout according to the data block 403 of the CD media 401 (Figure 23) of the 3rd example of the present invention.As shown in figure 24, the first frame zone 501 is positioned at the beginning of each data block 403, and a plurality of the second frame zones 502 are positioned at after the first frame zone 501.The first frame zone 501 and a plurality of the second frame zone 502 form a data block 403.In Figure 24, after the zone shown in the regional on the left side shown in the right.

The first frame zone 501 is included in its first retaining zone PA that begins, follow at thereafter the second retaining zone VFO and at the 4th retaining zone PS at its end.Each second frame zone 502 is included in its 3rd retaining zone SY that begins and follows data area DATA thereafter.

In the 3rd example of the present invention, the first retaining zone PA, the second retaining zone VFO, the 3rd retaining zone SY and data area DATA have with first example in identical effect, will be not described in detail.The difference of the 3rd example and first example is that the 4th retaining zone PS provides at the end in the first frame zone 501.

The 4th retaining zone PS has and helps transcriber (especially when reading a data block 403a corresponding to the beginning of the data of addition record) when reading each data block 403 to detect error-free the effect of the beginning in the second frame zone 502.Data are recorded among the data block 403a by following.In the first of the first retaining zone PAa of the first frame zone 501a and the second retaining zone VFOa (since the first retaining zone PAa several E byte), with an adjacent data block 403 before data block 403a record data side by side.That is, PA pattern and record being finished VFO part 2101 is recorded among the 501a of the first frame zone.(addition record (link) is carried out in several S since the first retaining zone PAa (S≤E) individual byte) beginning among data block 403a from position that last registration stops.That is, start-of-record VFO part 2102 and PS pattern are recorded among the first frame zone 501a (the 3rd zone).The 3rd zone comprises the 4th a retaining zone PS that wherein will record the zone of start-of-record VFO part 2102 and wherein will record the 5th synchronizing code sequence (PS pattern).

In Figure 24, adjacent the second frame zone after the 501a of the first frame zone is represented by label 502a.The second frame zone 502a and other the second frame zones 502 have with top with reference to figure 2 described the second frame zones 202 similar structures.In the following description, the 3rd retaining zone SY that comprises in the 502a of the second frame zone is expressed as " SYa " especially.

As top described in the prior art part, transcriber relates to various mistakes factors, for example is used for the rotation shake of the table motor of rotation CD media, frequency of record channel clock etc.This mistakes factor causes starting position discontinuous of the additional data record in the second retaining zone VFOa.Therefore, compare with the length in the first frame zone 501 of each other data block 403, the length of the first frame zone 501a is owing to mistake (discontinuous) changes.When this situation occurs, when transcriber adopts the second retaining zone VFO reading out data, even carry out definitely the level amplitude limit that partly carried out by PLL and the locking of clock frequency/phase place, also be difficult to correctly detect the 3rd retaining zone SYa of the beginning that is positioned at the second frame zone 502a.When the 3rd retaining zone SYa was not correctly detected, the data area DATAa after the 3rd retaining zone SYa can not correctly be modulated.Consequently, occur one and read mistake.

In the 3rd example of the present invention, increased the beginning that the 4th retaining zone PS detects the second frame zone 501a definitely.As long as detect the 4th retaining zone PS, though when the 3rd retaining zone SYa is not correctly detected also modulating data zone DATAa correctly.Like this, can increase prevention ability to mistake.

In the 3rd example of the present invention, adopt the run-length limited code with parameter d=2, k=10, m=8, n=16 and r=1 that is used for modulation to carry out the mark lengths record.That is, be recorded in data bit stream among the DATA of data area and comprise that having Tmin is that 3 and Tmax are 11 record mark or space.

Figure 25 has shown an example of a pattern (PS pattern) that will be recorded among the 4th retaining zone PS, and this example is desirable especially in the 3rd example of the present invention.Pattern shown in Figure 25 is { 0,000 0,100 0,100 1,000 0,010 0,001 0,010 00,001,000 0,010 0001 0000} in the NRZ representation.This pattern has 48 channels bits altogether.This pattern has following feature: (i) strong auto-correlation; (ii) DSV=0; And (iii) by the partial mode that obtains with 4 partition modes be five types 0000,1000,0100,0010 or 0001 in one.When the run-length limited code that will have parameter d=2, k=10, m=8, n=16 and r=1 was used for the modulation of data area DATA, the pattern shown in Figure 25 had the length of 3 bytes.This pattern is desirable when adjacent the second retaining zone VFO in front has the 4T record mark/space of repetition.This pattern is described in detail in Jap.P. No.3098258.

Figure 26 has shown another example of a pattern (PS pattern) that will be recorded among the 4th retaining zone PS, and this example is desirable especially in the 3rd example of the present invention.Pattern shown in Figure 26 is { 00,000 00,000 10,000 00,000 01,000 0,000,000,100 00000 00010} in the NRZ representation.This pattern has 45 channels bits altogether.This pattern has following feature: (i) comprise 11T record mark and the 11T space of alternately repeating twice; And (ii) has a little absolute value to 1 DSV.When the run-length limited code that will have parameter d=2, k=10, m=8, n=15 and r=1 was used for the modulation of data area DATA, the pattern shown in Figure 26 had the length of 3 bytes.This pattern sequence after modulation is desirable especially when not comprising repetition four times or more 11T record mark or space, because this pattern provides the enough code distances that certainly may reside in all types of patterns in data area DATA and other zones, and is the high resistance error-detecting.

Figure 27 has shown another example of a pattern (PS pattern) that will be recorded among the 4th retaining zone PS, and this example is desirable especially in the 3rd example of the present invention.Pattern shown in Figure 27 is { 000 000 000 010 000 001 000 000 100,000 000 001} in the NRZ representation.This pattern has 36 altogether.This pattern has following feature: the pattern that (i) comprises 11T7T7T11T; And (ii) have one and equal 0 DSV.When the run-length limited code that will have parameter d=1, k=7, m=2, n=3 and r=1 was used for the modulation of data area DATA, the pattern shown in Figure 27 had the length of 3 bytes.This pattern is desirable especially, provide enough code distances because this has comprised between all types of patterns of pattern in may reside in data area DATA and other zones of pattern of two (Tmax+3)=11T (Tmax is maximum reversal interval), thereby be the high resistance error-detecting.

A kind of in the method for CD media 401 identifying recording layers with above-mentioned data layout with similar in the method described in first example, be not described in detail here.

Figure 28 has shown another example of a pattern (PS pattern) that will be recorded among the 4th retaining zone PS, and this example is desirable especially in the 3rd example of the present invention.Pattern shown in Figure 28 is " 000000000001000000000001000000000001000000000001 " in the NRZ representation.This pattern has 48 channels bits altogether.This pattern has following feature: (i) comprise 12T record mark and the 12T space of alternately repeating twice; And (ii) have one and equal 0 CDS.When 8/16 modulating system is used among the DATA of data area, be not present in any data bit stream among the DATA of data area as the 12T of (Tmax+1) position.When the pattern in 12T record mark and 12T space is repeated 4 times, such pattern with can significantly be expanded by the code distance between the data bit stream of 8/16 modulation acquisition.Therefore, as shown in figure 28 pattern is anti-error-detecting very to heavens.

Have at adjacent the second retaining zone VFOa (Figure 24) in front in the situation of a pattern " 0001000100010001... " that wherein repeats 4T record mark and 4T space, the DSV value all remains on 0 since the final position to the 4th retaining zone PS of the second retaining zone VFOa.Therefore, the clipping lever that data are carried out the level amplitude limit of being carried out by transcriber can be stable.This is favourable for reproducing in adjacent pattern in the included retaining zone SYa of the second frame zone of back 502a.

When using 8/16 modulating system, pattern shown in Figure 28 has the length of 3 bytes.When the first frame zone 501a (Figure 24) has the length of 93 bytes and the 3rd synchronizing code sequence PA when having the length of 2 bytes, the second retaining zone VFOa (Figure 24) has the length of 88 bytes.

Figure 29 has shown another example of a pattern (PS pattern) that will be recorded among the 4th retaining zone PS, and this example is desirable especially in the 3rd example of the present invention.Pattern shown in Figure 29 is " 000000001000000000000100000000000010000000010 " in the NRZ representation.This pattern has 45 channels bits altogether.This pattern has following feature: the pattern that (i) comprises a 9T13T13T9T; And (ii) has a little absolute value to 1 DSV.When the run-length limited code that will have parameter d=2, k=10, m=8, n=15 and r=1 was used for the modulation of data area DATA, the pattern shown in Figure 29 had the length of 3 bytes.

This pattern comprises pattern and the pattern with (Tmax-2) position with (Tmax+2) position that repeats respectively twice.Therefore, can significantly be enlarged with the same in the situation of the pattern shown in Figure 28, shown in Figure 29 pattern and the code distance of modulating between the rear data bit stream.In addition, pattern shown in Figure 29 is the combination of long record mark/long spacing, but has an average reversal interval, that is, a required edge of phase bit comparison of being carried out by data PLL appears in every Tmax.This equals the maximum frequency that the edge occurs, and does not therefore detect the minor face impact that the edge produces by a rapid lapse of time cycle in the data PLL of transcriber.

Since long record mark be ordered as (Tmax-2) (Tmax+2) (Tmax+2) (Tmax-2), so can detect with higher reliability a partial mode.The whole pattern that records among detected the 5th synchronizing code sequence PS of method that replacement is mated fully by an employing, can only detect the first half of this pattern, namely (Tmax-2) (Tmax+2), perhaps can only detect the later half of this pattern, namely (Tmax+2) (Tmax-2).Its reason be in addition the first half or later half also can be present in all types of patterns in data area DATA and other zones and keep enough code distance.Therefore, pattern shown in Figure 29 is the high resistance error-detecting, is desirable especially.

Figure 30 has shown another example of a pattern (PS pattern) that will be recorded among the 4th retaining zone PS.For example, when being used to the modulation of data area DATA, the pattern that shows among Figure 30 is especially desirable when the run-length limited code with parameter d=1, k=7, m=2 and n=3 (so-called (1-7) modulating system).

The pattern that shows among Figure 30 is " 001000001000000000100000000010000010 " in the NRZ representation.This pattern has 36 channels bits altogether.This pattern has following characteristic: (i) comprise the pattern of 6T10T10T6T, and (ii) have and equal 0 CDS.According to known (1-7) modulating system that 8 bit binary data is transformed to 12 bit channel code words, the pattern that shows in Figure 30 has the length of 3 bytes.

Since long record mark be ordered as (Tmax-2) (Tmax+2) (Tmax+2) (Tmax-2), so can detect with higher reliability a partial mode.The method that replacement is mated fully by a use detects is recorded in whole pattern among the 5th synchronizing code sequence PS, the first half of detecting pattern only, namely (Tmax-2) (Tmax+2), or the later half of detecting pattern only, namely (Tmax+2) (Tmax-2).Its reason be in addition the first half or later half also can be present in all types of patterns in data area DATA and other zones and keep enough code distance.Therefore, pattern shown in Figure 30 is the high resistance error-detecting, is desirable especially.

Figure 31 has shown another example of a pattern (PS pattern) that will be recorded among the 4th retaining zone PS.Pattern shown in Figure 31 is " 0100100000001000000000001000000000001000000010010 " in the NRZ representation.This pattern has 48 channels bits altogether.This pattern has the feature of the pattern that comprises a 8T12T12T8T.This pattern is desirable when the run-length limited code that will have parameter d=1, k=9, n/m=1.5 is used for the modulation of data area DATA.The same with pattern shown in Figure 30, this pattern comprise (Tmax-2) (Tmax+2) (Tmax+2) therefore be the high resistance error-detecting (Tmax-2).As carrying out 8T record mark or space and inserting the result that 8T records two 3T spaces in mark or space or records the NRZI record of mark, the total length of record mark part equals the total length (wherein CDS=0) of space segment.Pattern shown in Figure 31 is symmetrical at circumferencial direction.Therefore, even (wherein, the amplitude of the record amplitude of mark part and space segment is asymmetrical relative to one another asymmetric; When the well known phenomenon that is used for caused reproduced signal deteriorates when the power of CD media identifying recording layer changes) when occurring, pattern shown in Figure 31 also can stably be detected.

Because pattern shown in Figure 31 begins with 3T, so when the pattern among adjacent the second retaining zone VFO before the 4th synchronizing code sequence PS is the 3T of (Tmin+1), i.e. repetition, in the continuity better (satisfying easily run-length restriction) of link position.

As mentioned above, the first frame zone 501 corresponding to a linking frames zone comprises the first retaining zone PA, the second retaining zone VFO and the 4th retaining zone PS.Because such structure, even when the length in frame zone changes owing to the various fluctuation mistakes factors of drive unit, the data that are recorded in the second frame zone 502 also can stably be read.Like this, the CD media that has high error resilience can may realize by system overhead with minimum.Like this, the reliability of transcriber can keep higher.

In example shown in Figure 24, data block 403a is not shown as and comprises a sector.Data block 403a can have one as top with reference to figure 9 described sectors.Also as top described with reference to figure 9, the guiding frame of each sector zone can have the different synchronizing code sequence (SY0 and SY) that is recorded in wherein with other frame zones.In this case, the beginning of sector or data block can more easily be detected, and has therefore significantly improved the reliability of information record reproducing.

As mentioned above, in the 3rd example of the present invention, the information mark road 402 of CD media 401 is divided into some data blocks 403 (403a), and wherein each is a unit of recording and reconstruction.Each data block 403 (403a) comprises and is positioned at its first frame zone 501 (501a) that begins to locate and is positioned at least one second frame zone 502 afterwards, the first frame zone 501 (501a).Each first frame zone 501 (501a) comprises the first retaining zone PA, the second retaining zone VFO and the 4th retaining zone PS.Each second frame zone 502 comprises the 3rd retaining zone SY and wherein wants the data area DATA of user data.Carry out among the second retaining zone VFO of the beginning of data recording (link)/terminate in the first frame zone 501a (linking frames zone).Therefore, even when data are recorded in discontinuous mode, this uncontinuity also will be absorbed in the second retaining zone VFO.In the 3rd example of the present invention, the 4th retaining zone PS is positioned at after the second retaining zone VFO in the first frame zone 501 (501a).In the 4th retaining zone PS, the PS pattern (the 5th synchronizing code sequence) that is used for the end of identification VFO pattern is recorded.The identification at the end of VFO pattern is equivalent to the identification at the end of the first synchronizing code sequence (part 2102 among Fig. 1) of describing in first example.Because before link and after synchronizing information (data among the first retaining zone PA and the 4th retaining zone PS) be enhanced by this way (reinforce), data can be always stably reproduced.The PS pattern is used to specify all beginnings (that is, being used to specify the beginning of the first area data that are recorded) at least one the second frame zone (first area) of wherein recording at least one second frame (being collectively referred to as the first area data).The first area is positioned at the back of the 4th retaining zone PS.

In the 3rd example, the first frame zone (first area and the 3rd zone) comprises the first retaining zone PA, the second retaining zone VFO and the 4th retaining zone PS, can also comprise other synchronizing code sequence or data bit streams.

(example 4)

Figure 32 has shown the top view according to the CD-R medium 701 of the 4th example of the present invention.On the record surface of CD media 701, form in a spiral manner record mark road 702.Record mark road 702 is divided into some data blocks 703.In other words, on the record surface of CD media 701, data block 703 is arranged continuously in a circumferential direction and is formed information mark road 702.

Figure 33 has shown the data layout according to the data block 703 of the CD media 701 of the 4th example of the present invention.As shown in Figure 33, the first frame zone 801 is positioned at the beginning of each data block 703, and a plurality of the second frame zones 802 are positioned at after the first frame zone 801.The first frame zone 801 and a plurality of the second frame zone 802 have formed a data block 703.In Figure 33, a zone that shows on the right side is after the zone that the left side shows.

The first frame zone 801 is included in its first retaining zone PA that begins and at thereafter specific purpose data area DASP.Each second frame zone 802 is included in its 3rd retaining zone SY that begins and at thereafter data area DATA.

In the 4th example of the present invention, the first retaining zone PA, the 3rd retaining zone SY and data area DATA have with first example in identical effect, will not be described in detail.The 4th example is different from first example aspect following, be that specific purpose data area DASP arranges the first frame that begins the to locate zone 801a (being included in the first frame zone of the vectoring information piece 703a of ECC piece) that is arranged in the ECC piece, rather than be arranged in the second retaining zone VFO in the first frame zone 201.The first frame zone 801 of each data block except the vectoring information piece of ECC piece can have the structure identical with the first frame zone 801a.

In the 4th example of the present invention, as shown in Figure 33, the ECC piece 804 that forms an error check code comprises four continuous data blocks 703.An error check code only solves and is included in four data area DATA in the continuous data block 703, and does not solve specific purpose data area DASP.

In the DASP of specific purpose data area, recorded comprise have from be included in data area DATA in the data bit stream of specific purpose data of the different purposes of user data.Be recorded in data among the DASP of specific purpose data area can be treated for the data independence that is recorded among the DATA of data area.What therefore, be recorded in data among the DASP of specific purpose data area reads that the data that do not require among the data area DATA that is recorded in the same data block 703 are read or error recovery etc.

At least one specific purpose data area DASP is provided in each data block.A plurality of specific purposes data area DASP is provided in each ECC piece.Therefore, can in the DASP of specific purpose data area, record expression corresponding to the data (specific purpose data) of the information of each data block or ECC piece.

For example, specific purpose data area DASP can have following purposes.

(purposes 1) is recorded in the data attribute of the user data among the data area DATA of each data block.

(purposes 2) relevant to be used for record data or to record the information of method of the feature of each data block.

Purposes 1 is used for the attribute of the user data that records on the basis of data block one by one.Irrespectively obtain this attribute with the user data among the data area DATA that is included in each data block.Therefore, in the situation that does not read user data, obtained this attribute.Therefore, for example when the information about copyright protection is included as attribute, can adopt each data block to come to carry out control for copyright protection as least unit.

Purposes 2 be at the basis of data block one by one record about being used for record data or recording the information of method of the feature of each data block.Irrespectively obtain such information with the user data among the data area DATA that is included in each data block.Therefore, in the situation that does not read user data, obtained this information.Therefore, in the time of in data being recorded in each data block or other data blocks, can use about being used for record data or recording the information of method of the feature of each data block.

An ECC piece comprises a plurality of data blocks.Data are rewritten on the basis of ECC piece one by one.The first frame zone 801a corresponding to the beginning of each ECC piece is used as the linking frames zone.Because such structure, a plurality of specific purposes data area DASP can be arranged in an ECC piece.It is effective being recorded in identical specific purpose data among all specific purpose data area DASP that are included in the ECC piece.By this way, even because rewrite in the time of to be read and to lose, can read the identical specific purpose data that are recorded among the DATA of other specific purpose data areas when the specific purpose data among the specific purpose data area DASP who is recorded in the first frame zone 801a.Like this, the specific purpose data can be reproduced safely.

In the example shown in Figure 34 A, the first frame zone 801a comprises the first retaining zone PA and the second retaining zone VFO.In the example shown in Figure 34 B, the first frame zone 801a comprises the first retaining zone PA, the second retaining zone VFO and the 3rd retaining zone PS.

In these examples, the second retaining zone VFO only provides in (corresponding to the linking frames zone) the guiding frame zone that begins to locate that is arranged in each ECC piece.Like this, be used in stable recording and be enhanced (that is the synchronous pattern when, record is used for guaranteeing to reproduce) at the needed synchronous mode of the reproduction of the data on the CD media 701.Specific purpose data area DASP is located in the first frame zone 801 that begins to locate of each data block the data block that begins to locate of each ECC piece.Therefore, even at the beginning/final position of data recording, data also can stably be read.Moreover, the specific purpose data can with each ECC piece in user data irrespectively be recorded or reproduce.

In the example shown in Figure 34 A and the 34B, comprise the second retaining zone VFO so that strengthen synchronous mode in the frame zone that begins to locate of each ECC piece.The present invention is not limited to this.When data are recorded in a plurality of ECC pieces with the form of a series of data recording, second and ECC piece subsequently in each guiding frame zone can have specific purpose data area DASP, rather than have the frame zone of the synchronous mode that is enhanced.

In the 4th example, described the situation that the first frame zone (first area and the 3rd zone) comprises the first retaining zone PA, the second retaining zone VFO and the 4th retaining zone PS, and the first frame zone (first area and the 3rd zone) comprises the situation of the first retaining zone PA and specific purpose data area DASP.The present invention is not limited to this.For example, when comprising specific purpose data area DASP or other synchronizing code sequence or data bit stream, the first frame zone can comprise the 4th retaining zone PS.

(example 5)

Figure 35 has shown the top view according to the CD-R medium 1001 of the 5th example of the present invention.On the record surface of CD media 1001, record mark road 1002 forms in a spiral manner.Record mark road 1002 is divided into some data block 1003a and 1003b.Information mark road 1002 is divided into inside part, center section and Outboard Sections.Inside part and Outboard Sections all are reproduction regions 1004 that is specifically designed to reproduction.Center section is rewritable area 1005.Each the data block 1003a that is included in the reproduction regions 1004 has the pit that is recorded in wherein.For example, use projection and the depressed portions of recording surface to assign to form pit.Among each data block 1003b in being included in rewritable area 1005, data will be come record by pen recorder.

Figure 36 has shown the data layout of the data block 1003a in the reproduction regions 1004 that is included in the CD media 1001 in the 5th example of the present invention.As shown in Figure 36, each data block 1003a is included in its first frame zone 1101 that begins to locate and is positioned at a plurality of the second frame zones 1102 afterwards, the first frame zone 1101.The first frame zone 1101 and a plurality of the second frame zone 1102 form a data block 1003a.In Figure 36, the zone that shows on the right side is located at the back in the zone of left side demonstration.

The first frame zone 1101 is included in its first retaining zone PA that begins to locate and specific purpose data area DASP subsequently.Each second frame zone 1102 is included in its 3rd retaining zone SY that begins to locate and data area DATA subsequently.The first retaining zone PA, the 3rd retaining zone SY and data area DATA have with first example in identical function, will not be described in detail.Specific purpose data area DASP have with the 4th example in identical function, will not be described in detail.

Figure 37 has shown the data layout of the data block 1003b in the rewritable area 1005 that is included in the CD media 1001 in the 5th example of the present invention.As shown in Figure 37, each data block 1003b has the structure identical with data block 1003a.Each data block 1003b is included in its first frame zone 1201 that begins to locate and is positioned at a plurality of the second frame zones 1202 afterwards, the first frame zone 1201.The first frame zone 1201 and a plurality of the second frame zone 1202 form a data block 1003b.In Figure 37, the zone that shows on the right side is located at the back in the zone of left side demonstration.

The first frame zone 1201 is included in its first retaining zone PA that begins to locate, the second retaining zone VFO subsequently and the 4th retaining zone PS.The second frame zone 1202 is included in its 3rd retaining zone SY that begins to locate and data area DATA after the 3rd retaining zone SY.

The first retaining zone PA, the second retaining zone VFO, data area DATA and the 3rd retaining zone SY have with first example in identical function, will not be described in detail.The 4th retaining zone PS have with second example in identical function, will not be described in detail.The 4th retaining zone PS can randomly be provided.

As shown in Figure 36 and 37, a reproduction regions 1004 and rewritable area 1005 all are divided into a plurality of data blocks and have each other similar frame structure.Therefore, although two zones have with different physical forms records (namely, utilize the projection of record surface and recessed part record, or the phase transformation that utilizes recording layer is recorded) data, the reproduction step (the level amplitude limit of data, PLL, demodulation etc.) after having obtained to reproduce RF can be carried out in almost identical mode in a reproduction regions 1004 and rewritable area 1005 at least.Therefore, transcriber does not need to comprise two dissimilar reproducing circuits, i.e. reproducing circuit and a reproducing circuit that is used for rewritable area that is used for reproduction regions.Like this, can simplify the structure of reproducing circuit, reduce like this cost of transcriber.

The inner structure of data block 1003b in its first frame zone 1101 and 1201 that begins to locate that is included in the data block 1003a in the reproduction regions 1004 and is included in the rewritable area 1005 differs from one another.

Be included in the first frame zone 1201 of vectoring information piece of each the ECC piece in the rewritable area 1005 corresponding to the linking frames zone of the beginning/final position that comprises additional data record.As describing in detail in first example, when being recorded in discontinuous mode, data block subsequently need to correctly be reproduced at the beginning/final position (linking frames zone) of additional data record when data.For this purpose, the first frame zone 1201 comprises that the first retaining zone PA, the second retaining zone VFO and the 4th retaining zone PS are in order to strengthen synchronizing information.In addition, begin and termination among the second retaining zone VFO that data recording can not have user data to be recorded therein.

The first frame zone 1101 in the reproduction regions 1004 is corresponding to the system overhead zone that does not have user data to be recorded in it.In this zone, because data are not rewritten, so the data uncontinuity does not occur.Therefore, in this zone, can irrespectively reproduce with user data, representative can be recorded corresponding to the data (specific purpose data) of the information of each data block.For this purpose, specific purpose data area DASP provides behind the first retaining zone PA, so can be recorded with the information that user data irrespectively reproduces.

In the example shown in Figure 35, CD media 1001 comprises a reproduction regions 1004 and rewritable area 1005.CD media 1001 can only have a reproduction regions 1004.

As mentioned above, in the CD media 1001 in the 5th example of the present invention, the data block that is included in the reproduction regions 1004 has identical frame structure with data block in being included in rewritable area 1005.This helps to reduce the scale of the reproducing circuit of drive unit.

In the CD media 1001 in the 5th example of the present invention, in the first frame zone 1101 in each data block in a reproduction regions 1004 or the data block in rewritable area 1005 is not that the first frame zone 1201 of link area can comprise the specific purpose data area DASP that substitutes the zone that is used for strengthening synchronism.Like this, can be recorded or be reproduced as the specific purpose data with the information that user data is irrespectively processed.For example, the intrinsic information of information, each drive unit of relevant copyright protection or can be recorded or reproduce for the information of using in the future.This helps the expansion in the use of CD media and recording and reconstruction device widely.

In the 5th example, described the first frame zone (first area and the 3rd zone) and comprised the situation of the first retaining zone PA, the second retaining zone VFO and the 4th retaining zone PS and the situation that the first frame zone (first area and the 3rd zone) comprises the first retaining zone PA and specific purpose data area DASP.The present invention is not limited to this.For example, when comprising specific purpose data area DASP or other synchronizing code sequences or data bit stream, the first frame zone can comprise the 4th retaining zone PS.

(example 6)

Figure 38 has shown the structure according to the information record carrier (pen recorder) 1710 of the 6th example of the present invention.For example, information record carrier 1710 information recording/on CD media 101 (Fig. 1), CD media 3101 (Fig. 8), CD media 401 (Figure 23) or CD media 1001 (Figure 35).In the following description, information record carrier 1710 information recording/on the CD media 3101 of in second example, describing in detail.

Recording and reconstruction shaven head 1701 is recorded in data on the CD media 3101, or read pre-recorded on CD media 3101 data or be recorded in data on the CD media 3101 by a device.

For example, recording and reconstruction shaven head 1701 comprise for the light source of tracer signal (for example, semiconductor laser) optically, be used for record data WTDT as one man driving light source driving circuit, be used for assembling light that light source sends or for detection of by the light of CD media 3101 reflections with light is read as the optical system of a signal and is used for a signal reproduction that reads is the photoelectric commutator of electric signal RF at the record surface of CD media 3101.

Signal level amplitude limit part 1702 amplifies the signal RF that read by recording and reconstruction shaven head 1701 and the processing by necessity comes signal RF is carried out the level amplitude limit.

Mode detection detects the synchronizing code sequence consistent with the data layout of CD media 3101 with sync section 1703 usefulness by the level sliced data RDDT that signal level amplitude limit part 1702 obtains, and identifies in real time the positional information of the data that read by recording and reconstruction shaven head 1701.The detailed built-in function of mode detection and sync section 1703 will be described later.

The operation of timing controlled part 1704 control ECC coded portions 1705 and modulating part 1706 makes the data that must record be recorded on the assigned position of CD media 3101 based on the positional information ADR that obtains by the Real time identification of being carried out by mode detection and sync section 1703.Except being used for the control operation of reading, timing controlled part 1704 also utilizes positional information ADR execution to be used for moving recording with the search operation that reproduces shaven head 1701 so that signal can be read at the assigned position of CD media 3101 or record.

ECC coded portion 1705 redundant data, such as error check code etc. add to from the outside input of information record carrier 1710 with the user data that is recorded, and this redundant data is encoded to the form of regulation.ECC coded portion 1705 also outputs to modulating part 1706 to the data ECCDT after encoding based on the record operation timing signal WTGT from timing controlled part 1704.ECC coded portion 1705 usefulness act on reception from the receiving unit of the user data of the outside of information record carrier 1710.

Modulating part 1706 receives by ECC coded portion 1705 coded data ECCDT, uses the modulating system modulating data ECCDT of regulation, and the data that obtain are outputed to recording and reconstruction shaven head 1701 as record data WTDT.

Information record carrier 1710 in the 6th example of the present invention passes through the cooperation of said units and unites information recording/on CD media 3101.For other record data (link) after being positioned at the data block that has recorded data, need to carry out accurate record to the data that recorded.

Information record carrier 1710 should correctly detect the data that have been recorded the position and with its accurately synchronous operation be very important.For this purpose, use is by the data of the level amplitude limit of recording and reconstruction

shaven head

1701 and 1702 reproductions of level amplitude limit part, the various synchronizing code sequences that detection is described in detail in second example are to obtain the operation of correct positional information, and namely the operation of mode detection and sync section 1703 is very important.For example, positional information ADR comprises sector position SPt, frame position FPt and byte location BPt.

Figure 39 has shown the example of the inner structure of mode detection and sync section 1703, and it comprises such as lower unit.

SY0 mode detection part 1901 detects the SY0 pattern and exports SY0 detection signal SY0DET from the data RDDT of level amplitude limit.SY0 mode detection part 1901 is used as the first test section for detection of SY0 pattern (the second synchronizing code sequence).

PA mode detection part 1902 detects the PA pattern and exports PA detection signal PADET from the data RDDT of level amplitude limit.PA mode detection part 1902 is used as the 3rd test section for detection of PA pattern (the 3rd synchronizing code sequence).

SY mode detection part 1903 detects the SY pattern and exports SY detection signal SYDET from the data RDDT of level amplitude limit.

1 frame timer 1904 is from the byte location signal BPt and the frame-synchronizing impulse FRMPLS that begin to identify byte location and in real time output reflection recognition result in each frame zone.For example, 1 frame timer 1904 comprises for the first segment count (not shown) and the byte location detection window generating portion (not shown) that is used to synchronizing code sequence generation detection window calculated at the byte number (93 byte) in a frame zone or the number of channels bits (being 1488 channels bits in the situation of 8/16 modulating system).1 frame timer 1904 receives detection signal SY0DET, PADET and SYDET and adjusting built-in the first segment count when suitably controlling detection window for built-in (built-in) byte location detection window generating portion of the synchronous displacement that prevents from being produced by the error-detecting of pattern from mode detection part 1901 to 1903 respectively.The count value that the first segment count obtains (byte location that begins to locate in expression frame zone) is outputted as byte location signal BPt, and frame-synchronizing impulse FRMPLS byte location (approximately per 93 bytes) in regulation in a frame is exported once.

The position that 1 frame timer 1904 is predicted the synchronizing code sequence basically based on the mode detection result of adjacent synchronizing code sequence in front, and in expection will detect time cycle of synchronizing code sequence, open detection window.When the detection signal to the synchronizing code sequence was received in this time cycle, 1 frame timer 1904 judged that correct synchronizing code sequence is detected and the count value BPt of the first segment count is predisposed to a setting.Prevalue is not to be necessary for 0, judges but consider to detect needed time delay.

The number of the byte in each frame equates in these frames.Therefore, byte location detection window generating portion control detection window, in order to open the official hour cycle at the byte cycle of each regulation (particularly, about per 93 bytes, this is the quantity of byte in the frame zone).The width of detection window can consider that all fluctuating factors about the signal-obtaining carried out by recording and reconstruction shaven head 1701 (for example judge, by the living jittering component of rotation wave movable property, the deflection of CD media 3101 etc., or the data uncontinuity in the linking frames zone).

Frame position in frame counter 1905 each sector of identification, and frame position signal FRt and the sector synchronizing pulse SCTPLS of in real time output reflection recognition result.For example, frame counter 1905 comprises the second segment count (not shown) of counting for to the frame number (26 to 27 frame) of a sector, and is used to the first synchronizing code sequence SY0 and the 3rd synchronizing code sequence PA to produce the frame position prediction window generating portion (not shown) of prediction window.Frame counter 1905 is from 1 frame timer, 1904 received frame synchronizing pulse FRMPLS and be added to built-in the second segment count.Frame counter 1905 also partly receives detection signal SY0DET and PDDET from each mode detection, and by being used for preventing that the built-in frame position prediction window generating portion that error-detecting owing to pattern produces synchronous displacement from suitably adjusting built-in the second segment count in the control forecasting window.

Frame position prediction window generating portion considers that the order that these patterns occur is each SY0 pattern and prediction window of PA mode producing.As described in detail in second example, each synchronizing code sequence is only detected with the order of regulation.For example, the second synchronizing code sequence SY0 in a sector detected once (in 26 frame zones once; Or in 27 frame zones that comprise the first frame zone 201 (Fig. 9) once).Utilize this point, frame position prediction window generating portion can be prediction window of each synchronizing code sequence generation.

When output detection signal SY0DET when the prediction window for the SY0 pattern is to open, frame counter 1905 is predisposed to 0 to the count value FPt of the second segment count.When output detection signal PADET when the prediction window for the PA pattern is to open, frame counter 1905 is predisposed to 26 to the count value FPt of the second segment count.Unless detection signal is output, the count value FPt of the second segment count is increased 1 when each frame-synchronizing impulse FRMPLS output.By this way, the count value of built-in the second segment count is outputted as frame position signal FPt, sector synchronizing pulse SCTPLS in a sector the regulation frame position on (per 26 to 27 frame zones) be output once.

Sector position in sector counter 1906 each data block of identification, and the sector position signal SPt of in real time output reflection recognition result.For example, sector counter 1906 comprises the 3rd segment count (not shown) for the number of sectors (8 sectors) of a data block of counting, and is used to the 3rd synchronizing code sequence PA to produce the sector position prediction window generating portion (not shown) of prediction window.Sector counter 1906 receives sector synchronizing pulse SCTPLS and is added to (count up) built-in the 3rd segment count from frame counter 1905.Sector counter 1906 also receives detection signal PADET from PA mode detection part 1902, and by being used for preventing because the built in fan zone position prediction window generating portion of the synchronous displacement that the error-detecting of pattern produces is suitably adjusted built-in the 3rd segment count in the control forecasting window.

Sector position prediction window generating portion is considered the order that the PA pattern occurs, and is PA mode producing prediction window.As described in detail in second example, the 3rd synchronizing code sequence PA only occurs once in 8 sectors.Sector prediction window generating portion can utilize this to put to produce prediction window.

When output detection signal PADET when the prediction window for the PA pattern is to open, sector counter 1906 is predisposed to 0 to the count value SPt of the 3rd segment count.Unless detection signal PADET is output, the count value SPt of the 3rd segment count is increased 1 when each sector synchronizing pulse SCTPLS output.By this way, the count value of built-in third part is outputted as sector position signal SPt.

Having the mode detection of above-mentioned inner structure and sync section 1703 uses the data RDDT of the level amplitude limit that reads from CD media 3101 to detect each the synchronizing code sequence (pattern) that is included in the data layout of describing in detail second example.Like this, the positional information of reading out data, be that sector position SPt, frame position FPt and byte location BPt are obtained in real time.Use is from such positional information of mode detection and sync section 1 703 outputs, and timing controlled part 1704 (Figure 38) can produce and export to oligodactyly and show that ECC coded portion 1705 comes the record operation timing signal WTGT of executive logging operation.

The inner structure that shows in Figure 39 only is an example.The inner structure of mode detection and sync section 1703 is not limited to this.In the example that shows in Figure 39, SY0 pattern, SY pattern and PA pattern are used as detected synchronizing code sequence.The PS pattern of describing in the 3rd example can be used in addition.In this case, the quantity of detected pattern has increased, so net synchronization capability and positional information recognition performance have improved.This will describe with reference to Figure 40 below.

All positional informations in the CD media 3101 can not only be identified with the synchronizing code sequence of Four types.With the synchronizing code sequence of Four types, the sector position in each data block, frame position and byte location can be identified, but the position of the current data block that reads in CD media can not be identified.In order to identify the position of the current data block that reads, need id information.For example, the Data Position identified region DataID that shows in Figure 14 is used to this purpose.

Figure 40 has shown another example of the inner structure of mode detection and sync section 1703, and it comprises following unit.The inner structure that shows in Figure 40 is further to comprise PS mode detection part 2001 with the difference of the inner structure that shows in Figure 39.With top with reference to the described same unit of Figure 39 and the identical inner signal that between the unit, transmits with corresponding label, will not be described in detail.

As describing in the 3rd example, for the purpose of the reliability that improves the beginning that detects each data block, the PS pattern is positioned at the end as the first frame zone 501a of link position.When data block comprised the sector, the first frame zone 501a needed adjacent before being located at the second frame zone that begins to locate of sector.Therefore, the PS pattern also is used to realize improving the purpose of the reliability that begins to locate that detects each sector.Because the PS pattern is positioned at the end of the first frame zone 501a, the PS pattern also is used to realize improving the purpose of the reliability that begins to locate that detects each frame zone.PS mode detection part 2001 is used as the 4th test section for detection of PS pattern (the 5th synchronizing code sequence).

For above-mentioned reason, be imported into 1 frame timer 2002, frame counter 2003 and sector counter 2004 as the output PSDET of PS mode detection result's PS mode detection part 2001, and in each counter, be used to location recognition.

Figure 41 has shown the data layout of CD media 3101 and the relation between the positional information.In Figure 41, the first frame zone is represented by " LF ".The first frame zone is represented as has the 4th retaining zone PS that describes in the 3rd example.Figure 41 has shown the example value of the positional information under the state that is established synchronously, i.e. sector position signal SPt, frame position signal FPt and byte location signal BPt.

Sector position signal SPt sequentially gets 0 to 7 value from the boot sector of each data block.In being in the first frame that begins the to locate zone LF of data block, sector position signal SPt is 0.

Frame position signal FPt sequentially gets 0 to 25 value from the boot sector of each sector, although the value of frame position signal FPt is 26 in the LF of the first frame zone.In all sectors in being included in each data block, the value of the frame position signal FPt in each frame zone (F0 is to F25) is in 0 to 25 the scope.

Byte location signal BPt sequentially gets 0 to 92 value from the boot sector in each frame zone.In all frame zones in being included in each sector, the value of byte location signal BPt the frame zone begin the place be 0.When through any one of SY0 pattern, SY pattern or PA pattern, the value of byte location signal BPt is 0 or 1.

Figure 41 has also shown the example waveform of the record operation timing signal WTGT that is produced by timing controlled part 1704 use location information (position signalling SPt, FPt and BPt).Be used at an ECC piece, the i.e. record data of four continuous data blocks at the record operation timing signal WTGT shown in Figure 41.When being in the HIGH level, record operation timing signal WTGT represents the record operation.At this moment wait, ECC coded portion 1705 outputs to modulating part 1706 to ECC coded data ECCDT.

Additional data are recorded in the first frame zone as the linking frames zone and carry out.In other words, the beginning of data recording/termination is always carried out in the second retaining zone VFO in the first frame zone.Therefore, from the S byte that begins to locate to count of the first frame that begins the to locate zone LF of the data block that begins that is in the ECC piece (in example shown in Figure 41, S=8), record operation timing signal WTGT changes into HIGH (height) level (record) from LOW (low) level.(in example shown in Figure 41, E=11), record operation timing signal WTGT changes into LOW level (termination of record) from the HIGH level from the E byte locating to count of beginning of the first frame that the begins zone LF that is in next ECC piece.

When correct when being performed synchronously, in the LF of first frame zone, SPt=0 and FPt=26.Therefore, record operation timing signal WTGT preferably is controlled as so that { SPt=0, FPt=26 in the current ECC piece, be in the HIGH level during BPt=S} (when data are recorded), and { SPt=0, FPt=26 are in the LOW level during BPt=E} in next ECC piece.

Like this, mode detection and sync section 1703 are used as the test section for detection of PA pattern (the 3rd synchronizing code sequence).Timing controlled part 1704 is used as for the determining section that begins to determine record start position based on detected PA pattern.As top described with reference to Fig. 2, timing controlled part 1704 can be determined record start position at random when each record is performed.

ECC coded portion 1705, modulating part 1706 and recording and reconstruction shaven head 1701 are together as the recording section that is used for the executive logging process.As top described with reference to Fig. 2, recording process comprises 2102 (being used for stably the first appended synchronization code sequence of rendering data) of record start-of-record VFO part step (Fig. 2), record the step of the second frame, the step of record PA pattern and in the VFO pattern, process record and finish VFO part 2101 (being used for stably the 4th appended synchronization code sequence of rendering data) step (Fig. 2).Have in the situation of the data layout of describing in the 3rd example in CD media, this recording processing comprises the step of record PS pattern.

Recording operating period, each synchronizing code sequence is detected (or cannot not being controlled to be detectedly).Therefore, do not preset each position signalling (SPt, FPt, BPt) and continuation interpolation.

As mentioned above, information record carrier 1710 comprises mode detection and the sync section 1703 that is used for detecting from pre-recorded data SY0 pattern and PA pattern when ought be additionally data being recorded to (link) on the information that is recorded in advance on the CD media or rewriteeing data.Information record carrier 1710 also comprises the timing controlled part 1704 of timing that is identified for beginning the record of additional data for the result who uses mode detection.Because such structure, detect at a high speed and stably data by pre-recorded to the first data unit (sector) or the second data unit (data block) begin locate in, information can be by addition record or rewriting.Like this, information record carrier has obtained the greatly positional precision of the record of improvement, has obtained like this reliability that strengthens.

Therefore, when being applied to large capacity, high-speed data storage device, video disc record device and multimedia recording device, information record carrier 1710 provides significant effect.

(example 7)

Figure 42 has shown the structure according to the information reproduction apparatus (transcriber) 1810 of the 7th example of the present invention.For example, the information of information reproduction apparatus 1810 reproducings on CD media 101 (Fig. 1), CD media 3101 (Fig. 8), CD media 401 (Figure 23) or CD media 1001 (Figure 35).In the following description, the information on the CD media 3101 in second example, described in detail of information reproduction apparatus 1810 reproducings.In Figure 42, signal level amplitude limit part 1702 and mode detection and sync section 1703 with top with reference to Figure 38 describe identical, will not be described in detail.

Reproduce shaven head 1801 and read the data that are recorded on the CD media 3101.For example, reproducing shaven head 1801 comprises for the light source (for example, semiconductor laser) of irradiation CD media 3101, for detection of by the light of the record surface reflection of CD media 3101 and this light is read as the optical system of a signal and is used for a signal reproduction that reads is the photoelectric commutator of electric signal RF.

The data RDDT of the level amplitude limit that PLL part 1802 usefulness are partly obtained by the signal level amplitude limit reproduces the position phase locked bit synchronization clock RDCLK with the edge of the data RDDT of level amplitude limit.

Data DEMDT after the data RDDT of demodulation part 1804 usefulness level amplitude limits and bit synchronization clock RDCLK come the demodulation rendering data and export demodulation.

Timing controlled part 1803 outputs to demodulation part 1804 to demodulation operation timing signal RDGT so that be recorded in the positional information ADR reproduction that the data of the assigned position of CD media 3101 can obtain based on the Real time identification by mode detection and sync section 1703 execution.When being the HIGH level, demodulation operation timing signal RDGT represents the demodulation operation of rendering data.Data DEMDT demodulation is only just exported in demodulation part 1804 when RDGT is the HIGH level after.

Timing controlled part 1803 outputs to signal level amplitude limit part 1702 to the level amplitude limit of the pattern that is used for control level amplitude limit control timing signal SLGT.When being the HIGH level, level amplitude limit control timing signal SLGT represents common level amplitude limit operator scheme.When SLGT was the HIGH level, signal level amplitude limit part 1702 was used reproducing signal RF control level clipping lever.When SLGT was the LOW level, signal level amplitude limit part 1702 remained on value when SLGT is the HIGH level to the level clipping lever, does not carry out control.

Timing controlled part 1803 will output to PLL part 1802 for the PLL control timing signal PLLGT of the pattern of controlling the bit comparison of PLL phase.When being the HIGH level, PLL control timing signal PLLGT represents the PLL follow the mode commonly used.When the PLLGT signal was in the HIGH level, PLL part 1802 was controlled to be built-in PLL the data RDDT that is phase-locked to the level amplitude limit.When the PLLGT signal was in the LOW level, PLL part 1802 kept this PLL and does not carry out control.

Except the control operation of be used for reproducing, timing controlled part 1803 is also carried out and is used for use location information A DR and moves and reproduce bare headed 1801 search operation so that signal can be read in the position of the regulation of CD media 3101.

ECC decoded portion 1805 is retrieved the data that need from the data DEMDT of demodulation, uses as required error check code to proofread and correct the data that retrieve when mistake is detected, and result's data are output as user data.

Reproduce shaven head 1801, signal level amplitude limit part 1702, PLL part 1802, demodulation part 1804 and ECC decoded portion 1805 together as being used for reproducing in the various synchronizing signals of the retaining zone of CD media 3101 and being recorded in the reproducing part of at least a portion of the user data among the DATA of data area.

Information reproduction apparatus 1810 by said units cooperation and unite to come the information of reproducing on CD media 3101.Information reproduction apparatus 1810 should correctly detect the position that is recorded in the data on the CD media 3101 with data layout of describing in second example and operate with its precise synchronization ground is very important.For this purpose, the various synchronizing code sequences that the level sliced data detection that use is reproduced by reproduction shaven head 1801 and level amplitude limit part 1702 is described in detail in second example are to obtain the operation of correct positional information, being the operation of mode detection and sync section 1703, is very important.The operation of mode detection and sync section 1703 is described in detail with reference to Figure 39 and 40 in the above, will be not described in detail.

Figure 43 has shown and has been used for reproducing at the operation waveform corresponding to the various timing signals of the first frame zone LF of linking frames and near it data.Level amplitude limit control timing signal SLGT becomes the LOW level at the BR1 byte place that locates to count since the first frame zone LF from the HIGH level, becomes the HIGH level at the BR2 byte place that locates to count since the first frame zone LF from the LOW level.As level amplitude limit control timing signal SLGT, PLL control timing signal PLLGT becomes the LOW level at the BR1 byte place that locates to count since the first frame zone LF from the HIGH level, becomes the HIGH level at the BR3 byte place that locates to count since the first frame zone LF from the LOW level.

Whether demodulated based on adjacent data block in front, control in every way demodulation operation timing signal RDGT.When adjacent data block in front is demodulated, demodulation operation timing signal RDGT is high level (as shown in phantom in Figure 43), but since the BR1 byte of locating to count of the first frame zone LF or before, in the LF of the first frame zone, change into the LOW level from the HIGH level.Then, since the BR4 byte of locating to count of the first frame zone LF or afterwards, demodulation operation timing signal RDGT becomes the HIGH level from the LOW level.When adjacent data block does not in front have when demodulated, demodulation operation timing signal RDGT the first frame zone LF to begin the place be LOW level (shown in solid line among Figure 43).

Here, the final position of hypothetical record is E the byte of locating to count since the first frame zone LF, the beginning position of record is that (S and E are less than the rational number of 93 bytes and satisfy that S≤E), the length of the 3rd synchronizing code sequence PA is 2 bytes since S the byte of locating to count of the first frame zone LF.Determine that the value of BR1, BR2, BR3 and BR4 is to satisfy 2≤BR1＜S, E＜BR2＜BR3＜BR4＜93.

In other words, by level amplitude limit control timing signal SLGT at least S the byte that begins to locate to count from E the byte of locating to count of the first frame zone LF to the regional LF of the first frame be set to the LOW level, the level clipping lever is held, in order to do not follow reproducing signal RF in the part that the quality of reproducing signal RF may differ from.As level amplitude limit control timing signal SLGT, PLL control timing signal PLLGT is the LOW level in the part of SLGT=LOW at least.But PLL control timing signal PLLGT is set to respect to the reformed point of level amplitude limit control timing signal SLGT in the back from the point that the LOW level becomes the HIGH level.Like this, in the quality of reproducing signal RF might relatively poor part, do not having to keep level amplitude limit control timing signal SLGT in the situation of PLL control, and, after having started the operation of following the level amplitude limit, restart the phase bit comparison between PLL and the level sliced data RDDT.The part that demodulation operation timing signal RDGT is set at least PLLGT=LOW is at the LOW level.But demodulation operation timing signal RDGT is set to respect to the reformed point of PLL control timing signal PLLGT in the back from the point that the LOW level becomes the HIGH level.Like this, demodulation operation not the quality of reproducing signal RF may be relatively poor part in be performed.

Various timing signals are set as described above, even when being recorded in the first frame zone LF (link area) and near the data it when reproduced, prevent the uncontinuity of the data that produce by link or by the deteriorated reproduction processes system that affects information reproduction apparatus in the recording layer that repeatedly rewrites the data generation.Like this, data can correctly be reproduced.

The specific purpose data of transcriber 1810 reproducings in the reproduction regions of CD media 1001 (Figure 35) are as follows.The PA pattern (replenishing the third pattern) that is recorded among the first retaining zone PA in the first frame zone 1101 (Figure 36) is detected by PA mode detection part 1902 (test section).Detect in response to this, the specific purpose data (specific purpose data) that are recorded among the DASP of specific purpose data area are reproduced.

Like this, transcriber 1810 comprises mode detection and the sync section for detection of the second synchronizing code sequence (SY0 pattern) and the 3rd synchronizing code sequence (PA pattern), and be used for to use the mode detection result to be identified for timing controlled part and the demodulation part of timing of the read operation of start information.Because such structure, transcriber 1810 can be in the beginning that detects at a high speed and stably the first data cell (sector) or the second data cell (data block) information reproduction.Like this, information reproduction apparatus 1810 can be at a high speed and rendering data stably.

Timing controlled part 1704 and signal level clipped signal 1702 are used as together for using the mode detection result to switch the level limiter mode switching part of the level limiter mode of reproducing signal in the specified period of the first frame zone LF.Timing controlled part 1704 and PLL part 1802 are used as together for reproducing the clock reproduction mode switching part of clock with reproducing signal bit synchronization ground.Because such structure, though when data be discontinuous or the quality of reproducing signal descends in link position, be recorded in link position and near its information also can stably be reproduced.As a result, information reproduction apparatus 1810 has the reliability of the information regeneration of remarkable enhancing.

Therefore, when being applied to large capacity, high-speed data memory storage, optic disk register and multimedia recording device, this information reproduction apparatus 1810 provides significant effect.

In above-mentioned seven examples, according to the present invention, CD media is used as information recording carrier.The present invention is not limited to CD media.For example, the present invention can be used for for example hard disk of magnetic recording media.Above-mentioned example does not limit the present invention.The present invention is only limited by claim.
