Fig. 2 explanation is with the ECC piece of DVD data layout by 5 configurations of ECC piece arrangement components, as shown in Figure 1.
The ECC piece be used as with to the user data of the input cell block of correction process in addition.
As shown in Figure 2, corresponding ECC piece of 16 sector datas of on CD, arranging continuously (0～sector, sector 15).Be included in each sector configuration in the ECC piece of Fig. 2 for having the matrix shape of 182 bytes * 13 row, like this, the ECC piece is configured to have 182 bytes * matrix shape of 208 row.
Fig. 3 illustrates the configuration of each sector.As shown in Figure 3,13 row of being made up of a sector are divided into two groups of data, and like this, (SY0～SY7) is added to every group (1456) of every data of being made up of 91 bytes to 32 bit synchronization sign indicating numbers as identification information item.Data division by each synchronous code subregions that is added of every data is configured to synchronization frame.Each synchronous code is used as the identification code that is used for discerning corresponding synchronization frame when reproducing the ECC piece.
As shown in Figure 3, every row is made up of two synchronization frames, and like this, each sector comprises 26 synchronization frame SF1～SF26 altogether.Therefore, each piece has the data configuration (data layout) that is divided into 16 * 26 synchronization frames altogether, so that arrange a piece.
In synchronous code, have the channel bit width 14T impulsive synchronization of (T represents every channel bit clock period), like this, the synchronous code pattern is longer than the pattern of the long-channel bit width 11T that appears at data division, makes and can distinguish synchronous code to discern it from data division.
Sequence (trains) in 9 channel bit of each head of each synchronous code has not coordination pattern respectively, so, 8 kinds of synchronous code SY0～SY7 are provided.As shown in Figure 3, the arrangement of synchronous code SY0～SY7 allows the Data Position in the identification sector.
The user data of input ECC piece arrangement components 5 is configured to the record data be made up of the ECC piece, so that record data are transferred to chained block insertion parts 6.
Chained block insertion parts 6 receives the record data that transmitted, so that chained block is inserted every pair of each boundary member between the contiguous ECC piece.
Fig. 4 is the situation of chained block is inserted in explanation at recorded data on the CD 2 and the boundary member between the additional data a synoptic diagram.
That is, shown in oblique line (hacures), chained block insertion parts 6 is inserted in chained block LB in two synchronization frames (the first synchronization frame SYF1 and the second synchronization frame SYF2) zone between the ECC piece of head of the last ECC piece of recorded data and new additional data.The identical configuration that has ECC piece as shown in Figure 3 near two ECC pieces before and after the chained block, but at least one yard type of the synchronous code SYX of two synchronization frames, SYY in the chained block, be different from common synchronous code SY0～SY7, so that be set to special synchronous code pattern.
Promptly, chained block insertion parts 6 is added the synchronous code SYX that is different from common synchronous code SY0～SY7 to the first synchronization frame SYF1 among the chained block LB of insertion, and the synchronous code SYY that is different from common synchronous code SY0～SY7 is added to the second synchronization frame SYF2 among the chained block LB of insertion.
At least one yard type of synchronous code SYX, the SYY that adds is different from the sign indicating number type of common synchronous code SY0～SY7, so that with reference at least one synchronous code SYX, SYY, allows partly to distinguish chained block LB from real data.On each synchronization frame SYF1 in being included in chained block LB and each data division of SYF2, as shown in Figure 4, record dummy argument (dummy) data replace real data or record data not.
In this embodiment, chained block insertion parts 6 each boundary member between every pair on the CD 2 contiguous ECC piece inserts chained block LB.In this configuration, when each new additional data of record on CD 2, chained block LB always is inserted between each recorded data and the additional data that each is new, and when comparing with the ECC piece that comprises 16 * 26 synchronization frames, chained block LB size is in 3 synchronization frames, and for example, size is more at 2 synchronization frames, the recording capacity of the feasible CD 2 of may avoiding waste, thus its recording capacity effectively utilized.
Yet, the invention is not restricted to structure at all boundary member insertion chained block LB.That is, chained block insertion parts 6 can select at least one boundary member between all contiguous ECC pieces so that insert at least one selected boundary member.
Fig. 5 be expression according to the data placement on the CD 2, comprise the synoptic diagram of the data division of the chained block LB that Fig. 4 shows.In Fig. 5, adopt data A as recorded data, and adopt ECC piece (n-1) at least one ECC piece as data A.Employing is followed data B behind the data A as additional data, and adopts ECC piece (n) first as the ECC piece of data B.As shown in Figure 5, the chained block LB that is made up of two synchronization frames inserts the boundary member between ECC piece (n-1) and the ECC piece (n).
Therefore, data recording unit 7 is carried out at the record that the rearmost end at ECC piece (n-1) stops data A so that move to chained block LB, thereby at its front end from ECC piece (n) opening entry data B.Chained block LB is inserted in coupling part between data A and data B under the interruption of the continuity from data A to data B situation once.
When reproducing as shown in Figure 5 thereon the CD of arranging data, carry out reproduction operation about data A so that arrive ECC piece (n-1), and finish reproduce data A after, detect the synchronous code SYX among the chained block LB.The sign indicating number type of synchronous code SYX is different from each the sign indicating number type of synchronous code SY0～SY7, so that can easily distinguish the part of chained block LB.Detect the concrete configuration of synchronous code SYX when data are reproduced in explanation hereinafter.By the way,, may detect synchronous code SYY, still, in this embodiment, detect synchronous code SYX so that distinguish chained block LB in order to distinguish chained block LB.
Then, with reference to figure 6, the track record according to the CD 2 of first embodiment is described hereinafter.
Fig. 6 is the synoptic diagram that the frame format that concerns between track record structure on the recording disk 2 not and the above-mentioned record data structure is described.The track record structure shows with its magnification ratio.
Fig. 6 top shows the address information item of the position in its each unique identification record data.The address information item is on the track record TR that before had been stored on the CD 2.Track record TR is vertical at it, and promptly the circumferencial direction of CD 2 is divided into address location AU, its each corresponding each address information item.
In other words, for example, should be recorded in the locational record data of address n and be recorded in correspondence and have on the address location AU of address information item of address value n.The address information item of corresponding each address location AU is stored in this manner, so that when the track record TR among each address location AU of swing, hunting period, the address information item by corresponding each address location AU carried out phase modulation (PM).
On the CD 2 of first embodiment, as shown in Figure 6, every of unit, calculated address AU, like this, after writing down each ECC piece, an address location AU and having write down on it who has write down the final data of an ECC piece on it follows the boundary member between another address location AU of beginning data of another ECC piece behind the described ECC piece, with consistent to the boundary member between should the synchronization frame of chained block.
Promptly, as shown in Figure 6, when synchronous code SYX follows the final data of ECC piece (n-1), write down the position of data of the rear end of the synchronization frame SYF1 that comprises synchronous code SYX in chained block LB thereon, with synchronous code SYX side back end opposite, consistent with last the rear end among the address location AU of corresponding ECC piece (n-1).In addition, as shown in Figure 6, when the first data front of synchronous code SYY, write down position thereon in the data of the front end of synchronous code SYY at ECC piece (n), the front end adjacent with the rear end of synchronization frame SYF1, consistent with first the front end among the address location AU of corresponding ECC piece (n).
By the way, Fig. 6 explanation, the record data that comprise an ECC piece and the data of the synchronization frame of the chained block LB of the either side of a corresponding ECC piece have been write down, corresponding 4 address location AU in the zone on the CD 2 on it.For example, the regional ARE on the CD 2 should write down on it and comprised ECC piece (n-1) and to the record data of the data of the synchronization frame of the chained block LB of either side that should ECC piece (n-1), 4 times of width of corresponding each address location.That is corresponding 4 the address location AU (n+1) of regional ARE～AU (n+4).
That is, corresponding its chained block of each ECC piece and each is recorded in each regional ARE, described zone by subregion so that the subregion of corresponding address unit AU, so can accurately distinguish the position of chained block by reference address unit AU.
As mentioned above, the information recording/reproducer 1 according to first embodiment comprises: ECC piece arrangement components 5 as the record data inking device, is used for having the data of above-mentioned data configuration for information recording carrier, configuration as DVD-RW, DVD-R etc.; Chained block insertion parts 6 is inserted device as chained block, and the chained block that is used for having described feature inserts record data.
In addition, comprise according to the information recording/reproducer 1 of first embodiment: data recording unit 7 as data recording equipment, as mentioned above, is used for for just as the information recording carrier of DVD-RW, DVD-R etc., control the record of additional data.
Then, with reference to figure 1 and Fig. 7, explain the chained block detecting operation that is undertaken by information recording/reproducer 1 when reproducing CD 2 according to first embodiment.
Fig. 7 is presented at from it to reproduce under the situation of chained block of CD, from the synoptic diagram of the waveform pattern of the signals of each parts 11,13,14 of information recording/ reproducer 1 and 15 outputs.
That is the target record track illumination beam on the CD 2 that drives for rotation from optical pick-up 3.Reflected light from the target record track on the CD 2 is detected by the detecting device in the optical pick-up 3.Will be from the detection signal of optical pick-up 3 input reproducing signal production part 11, make not form recessed district on the platform by the reproducing signal that changes its level according to the recessed district on the target track and platform thereof.For example, have the situation of the surveyed area of 4 divisions at the detecting device of optical pick-up 3, the signal plus that reproducing signal production part 11 will be detected by the surveyed area of 4 divisions in detecting device is so that produce reproducing signal.
Then, on the top of Fig. 7, when data division comprises the chained block LB of CD 2 as shown in Figure 5, the waveform pattern of display reproduction signal.Fig. 7 clearly represents: when the data B after the reproduction of data A before the reproduction of reproducing chained block LB and reproduction chained block LB, reproducing signal has stable level.On the contrary, Fig. 7 clearly represents: when reproducing chained block LB, the level distortion in the reproducing signal takes place.When record additional data when (data B), lose because the data between the data before and after the boundary member are uncertain between the data before and after the boundary member of additional data and recorded data synchronously, cause the above-mentioned level distortion in the reproducing signal.Allow the data before and after the boundary member synchronized with each other according to the configuration of the information recording/reproducer 1 of this embodiment.
Then, scale-of-two amplitude limit parts 12 with predetermined level with the reproducing signal amplitude limit so that to its binaryzation, thereby produce the binary signal of the Data Styles of the record data on the corresponding CD 2.According to the binary signal from scale-of-two amplitude limit parts 12, synchronous detection parts 13 detect to be distinguished common synchronous mode SY0～SY7 or is included in synchronous mode SYX and SYY among the chained block LB.Synchronous detection parts 13 output SYX detection signals are used for distinguishing the timing of the synchronous mode SYX that detects chained block LB.
As shown in Figure 7, the SYX detection signal is a pulse signal, and the detection timing t 0 of the synchronous mode SYX in the Data Styles of this pulse signal from be included in binary signal is transformed into high level, so that keep high level state at short notice.
Holding signal production part 15 produces holding signal according to the SYX detection signal from 13 outputs of synchronous detection parts, so that holding signal is offered PLL 14.Holding signal is the signal that is suitable for controlling the state of PLL error signal, and is suitable for distinguishing the schedule time that keeps the level of the PLL error signal in the chained block during it.
Then, the waveform pattern in the holding signal shows in Fig. 7.Holding signal has such waveform pattern and keeps high level up to process predetermined hold-time Ta so that the timing t 1 that signal descends at the SYX detection signal rises, so, behind predetermined hold-time Ta, signal descends in timing t 2, and wherein retention time Ta is defined as the elapsed time from t1 to t2.Shown in Fig. 7 bottom, the PLL signal keeps high level in retention time Ta.
Before the timing t 1, the waveform of PLL signal changes according to the state of a control of PLL 14.In timing t 2, PLL 14 forwards unlocked state to, then PLL 14 from timing t 2 to timing t 3, carry out and new catch operation up to through schedule time Tb, thus, after the timing t 2, the waveform of PLL error signal changes once more according to the state of a control of PLL 14.By the way, because the frequency of PLL 14 suitably is provided with when operation is caught in PLL 14 execution, time T b is the time that the coupling phase place of PLL 14 requires.
Data read parts 16 read the data division of following the synchronization frame of distinguishing according to the synchronous code that is detected by synchronous detection parts 13.Data read parts 16 also make this data division through the various signal Processing that reading of data partly requires, and comprise correction process etc., so that data division is exported as reproducing data.
According to each waveform pattern shown in Figure 7,, before process capture time Tb, be necessary to be provided with the final edge part of chained block LB in the situation of the chained block that reproduces CD.At first, retention time Ta is set to allow to avoid the time degree of the waveform distortion in this reproducing signal at least.Capture time Tb according to as the frequency band of PLL 14 etc. characteristic definite.The length of chained block LB must be provided with by considering retention time Ta and capture time Tb.Particularly, the length that chained block LB is set is that a synchronization frame makes capture time Tb shorten usually, so the frequency band of PLL 14 is wide.Therefore, the length of hope chained block LB is set to two synchronization frame or more.Yet in the situation of the characteristic that guarantees PLL 14, length that can chained block LB is set to a synchronization frame.Be provided with to such an extent that cross and exceed needed situation in the length with chained block LB, chained block LB relates to the recording capacity on the CD 2, so wish the length of chained block LB is arranged within 3 frames.
Configuration as within the length with chained block is arranged on 3 frames allows to reduce the size of the CD 2 that chained block requires, thereby has effectively utilized the recording capacity on the CD 2.
In this embodiment, in case reproduction processes arrives chained block LB, the PLL14 that sampling is handled as clock stops to extract clock signal, behind predetermined hold-time Ta, sampling clock signal once more, so, can the PLL error signal be remained on steady state value for holding signal Ta.As a result since when tracer signal switches to additional data the waveform distortion of reproducing signal, can prevent that about extracting the harmful effect of clock as the phase slip of PLL etc., thereby the frequency of stable control PLL and phase place are to extract clock signal.
In that above-mentioned chained block LB is applied to as the situation of the DVD-ROM of information reproduction recording medium, explain the configuration of the distortion of first embodiment.The purpose of this distortion is that the present invention is applied to DVD-ROM, but so that allows to guarantee above-mentioned record/writable information recording medium as DVD-RW/DVD-R and the compatibility between the DVD-ROM.
Fig. 8 is that expression comprises according to the synoptic diagram of going up the data division of the chained block LB identical with Fig. 5 as the DVD-ROM of CD 2.
Among Fig. 8, with Fig. 5 relatively and different points utilizes chained block LB as the subcode zone, at this subcode regional record the subcode of special effect arranged.By the way, other the point with Fig. 5 in identical.From Fig. 2 to Fig. 4 shown data configuration basic with Fig. 8 in identical, but subcode is recorded in two synchronization frame SYF1 being included among the chained block LB and the data division of SYF2, replacement dummy argument data.
Subcode zone among the DVD-ROM is a redundant area, because there is not data record thereon at all, yet, in this distortion, can be at the various control information items of subcode regional record reproducing control requirement.For example, may write the initial value that scrambler is handled, handle and carry out this scrambler in subcode regional record data.That is,, still, in this distortion,, can easily determine the initial value that scrambler is handled because write down this initial value as subcode in the past according to the initial value that the record position acquisition scrambler of record data is handled.
As the situation of subcode at the various control information items of subcode regional record, when reproducing DVD-ROM, must read this subcode zone, but, in this distortion, can detect the synchronous code SYX or the SYY that add chained block LB to, be identified simply to read various control information items thereby on chained block LB, write down various control information items.
About the information reproduction apparatus that is used to reproduce DVD-ROM of distortion comprises: comprise and the information reproduction apparatus of optical pick-up 3, reproducing signal production part 11, scale-of-two amplitude limit parts 12, PLL 14, holding signal production part 15, data read parts 16, CPU 20 and storer 21 components identical, so can detect chained block LB as mentioned above.By the way, when reproducing DVD-ROM, guarantee to extract continuously the situation of suitable clock signal, holding signal detection part 15 may be provided especially, but only need to detect synchronous code SYX.
As mentioned above, according to information recording/reproducer 1, when writing down record data on the former CD 2 of storing the address information item when considering the zone that comprises ECC piece and chained block LB, insert each boundary member between each ECC piece at the chained block LB that will have 2 synchronization frame length on the CD 2, and each synchronous code SYX, SYY that has special style respectively is added to chained block LB.When reproducing CD 2, detect synchronous code SYX to distinguish the position of chained block, so remain on hold mode at reproduction chained block period P LL14, thus, the data division period P LL that follows chained block in reproduction carries out the new operation of catching.
This configuration allows not form chained block in each ECC piece, prevents the error-correcting performance deterioration, and avoids whole ECC piece can not be used for record data.Use data division as the chained block enough shorter, allow to reduce the capacity of wasting in the video disc recording capacity than ECC piece.
As a result, may improve reliability of recording data, and not influence the error-correcting performance of each piece.In addition, also may remove the waste zone in each piece and prevent that the size of chained block from diminishing, thereby utilize the recording capacity of information recording carrier.
When reproducing CD, detect position that synchronous code SYX makes chained block by reliable recognition, and according to the position suitable ground control PLL 14 of chained block so that allow PLL 14 stably to extract clock signal, thereby the reliability of improvement reproducing signal.
Also may guarantee recorded data thereon as the CD of DVD-R, DVD-RW etc. and as DVD-ROM only reproduce compatibility between the CD, thereby improve the practicality of CD.
And, in this embodiment,, may allow when reproducing CD, to simplify the testing circuit that is used to detect chained block with regular data format configuration record data because chained block is formed on all close respectively boundary members of all ECC pieces.
(second embodiment)
Fig. 9 be explanation according to a second embodiment of the present invention insert the synoptic diagram of the situation of chained block as the recorded data on the DVD-RW/DVD-R of CD and the boundary member between the additional data.By the way, identical according to the functional-block diagram of the information recording/reproducer 1A of second embodiment with functional-block diagram according to the information recording/reproducer 1 of first embodiment, thereby the explanation of omitting the functional-block diagram of information recording/reproducer 1A.
As explain ground in first embodiment, chained block has basic task, be used for as the recording disk 2 of DVD-RW/DVD-R etc. on during the record additional data, additional data is separated with predetermined space and recorded data maintenance.But in this embodiment, chained block is formed on as only the reproducing on the CD 2 of DVD-ROM etc., so the record format of only reproducing CD 2 is identical with recording disk 2.
At first for the insertion operation of explaining chained blocks as the recording disk 2 of DVD-RW/DVD-R etc.
That is, in this embodiment, chained block insertion parts 6A, as showing ground by oblique line among Fig. 9, chained block LB is inserted in plating zone on the former track record that is formed on recording disk 2, so chained block LB occupies the plating zone, prevents that the data on the chained block LB are recorded.
The synchronous code SYX that chained block insertion parts 6A will be different from common synchronous code SY0～SY7 is added to the first synchronization frame SYF1.
The synchronous code SYX that increases has the sign indicating number type that is different from common synchronous code SY0～SY7, so can partly distinguish chained block LB from real data with reference to synchronous code SYX.In the plating zone, dummy argument data have as shown in Figure 8 been write down.
Then, Figure 10 is expression according to the synoptic diagram as the data configuration of the chained block of the DVD-RW/DVD-R of CD 2 of being applied to of second embodiment.As shown in figure 10, chained block is formed on the boundary member between preposition ECC piece (n-1) and the follow-up ECC piece (n).The plating zone is formed at the center section of chained block LB.Then, because when at the DVD-RW/DVD-R identifying recording layer, increased in chained block LB the synchronous code SYX on the head, so there be not data to be recorded in situation on the DVD-RW/DVD-R, unique plating zone is present among the chained block LB.
In Figure 10, the plating regional arrangement is among the chained block LB of 186 bytes in length 66 byte regions at total length, rather than the end district of the Head Section of its 60 byte long and 60 byte longs thereof.
Because when the plating zone that forms with the recessed district of a plating line very near the time near the posting field of chained block, the plating zone can make the recording film deterioration on the posting field, so, arrange the plating zone to leave the posting field of close chained block LB, so that stop deterioration near the posting field of chained block with preset distance.
Do not having data to be recorded in situation on the DVD-RW/DVD-R, the head of chained block LB be a sky, yet, there being data to be recorded in situation on the DVD-RW/DVD-R, synchronous code SYX is increased to the head of chained block.Because synchronous code SYY is at the plating region overlapping, so the synchronous code SYY that increases at chained block on the DVD-ROM is not increased to the chained block on the DVD-RW/DVD-R, so that do not read synchronous code SYY.
The shape of the track record in the chained block is presented at the bottom among Figure 10.Grooved tracks as track record is swung, so when at the track record identifying recording layer, the record mark of corresponding record data is formed on the grooved tracks, except that chained block.
The plating zone forms with the recessed district of the plating line that comprises recessed district of alternately arranged plating and platform.The pattern of the recessed district of plating line changes according to the dummy argument data.Prevent that data are recorded in the plating zone, even and the illegal copies record mark with at the plating regional record, the recessed district of plating line also makes to the interference of record mark can not reproduce record mark.Below this operation of explanation.
Then, explain the chained block detecting operation that carries out when reproduction during, by information recording/reproducer 1A with reference to figure 1 and Figure 11 according to second embodiment as the DVD-RW/DVD-R of CD 2.
Figure 11 is reproducing from it under situation of the chained block of the CD of DVD-RW/DVD-R for example, from the synoptic diagram of the waveform pattern of the signals of each parts 11,13,14 of information recording/reproducer 1 A and 15 outputs.
That is, from the optical pick-up 3 relative target record track illumination beams that rotate on the CD 2 that drives.Reflected light from the target record track on the CD 2 is detected by the detecting device in the optical pick-up 3.Will be from the detection signal of optical pick-up 3 input reproducing signal production part 11, so that the reproducing signal that changes its level according to the recessed district on the target track and platform thereof, platform is not form place, recessed district.
Then, on the top of Figure 11, shown the waveform pattern of the reproducing signal when data division comprises the chained block LB of CD 2.Figure 11 clearly represents, when data division before reproducing chained block LB and reproduction comprised the data division of the synchronous code SYX that is positioned at chained block LB head place, reproducing signal had the varying level in the level L2 scope at level L1.
Figure 11 knows that also the face of land shows, during not posting field in reproduce removing the chained block in plating zone, reproducing signal has constant level L2, and when reproducing plating when regional, and reproducing signal has the varying level in the level L3 scope at level L2.
The reason of the drift of signal level range is, the level nature of the reflecting bundle that whether causes with existence by the recessed district of plating relatively, the level nature inverse change of the reflecting bundle that whether causes by the existence of record mark.Reproducing signal shown in Figure 11 has different DC level in the zone, front and back of chained block with the plating zone.
When writing down record data on the chained block LB on CD 2, the record record mark makes on the recessed district of the plating line in its plating zone on grooved tracks overlapping, so, when the grooved tracks on the reproduction CD 2, may accurately obtain the reproducing signal of the record data on the corresponding chained block.Configuration described below on the contrary, when the data division of the front and back of reproducing chained block, must guarantee successively reproducing, so in this embodiment, can guarantee that the reproduction of the reproduction of the data division before the chained block and the data division behind the chained block is synchronous.
Then, as shown in Figure 1, similar first embodiment, scale-of-two amplitude limit parts 12 with predetermined level amplitude limit reproducing signal with its binarization, thereby produce the binary signal of the Data Styles of the record data on the corresponding CD 2.According to the binary signal from scale-of-two amplitude limit parts 12, synchronous detection parts 13 detect to be distinguished common synchronous mode SY0～SY7 or is included in synchronous mode SYX and SYY among the chained block LB.
Similar first embodiment, PLL 14 imports wherein binary signal so that sampling and the synchronous clock of reproducing signal.
Holding signal production part 15 produces holding signal holding signal is offered PLL 14 according to the SYX detection signal from 13 outputs of synchronous detection parts.Holding signal is the signal that is suitable for controlling the state of PLL error signal, and is suitable for distinguishing the schedule time that keeps the level of the PLL error signal in the chained block during it.
Then, the waveform pattern in the holding signal shows in Figure 11.Holding signal has such waveform pattern and keeps high level up to process predetermined hold-time Ta so that the timing t 1 that signal descends at the SYX detection signal rises, so, behind predetermined hold-time Ta, signal descends in timing t 2, and wherein retention time Ta is defined as the elapsed time from t1 to t2.Shown in Figure 11 bottom, the PLL signal keeps high level in retention time Ta.
Data read parts 16 read the data division of following the synchronization frame of distinguishing according to the synchronous code that is detected by synchronous detection parts 13.Data read parts 16 also make this data division through the various signal Processing that reading of data partly requires, and comprise correction process etc., so that data division is exported as reproducing data.
According to each waveform pattern shown in Figure 11,, before process capture time Tb, be necessary to be provided with the final edge position of chained block LB in the situation of the chained block that reproduces CD.At first, retention time Ta is set to allow to avoid the time degree of the waveform distortion in this reproducing signal at least.Capture time Tb according to as the frequency band of PLL 14 etc. characteristic definite.The length of chained block LB must be provided with by considering retention time Ta and capture time Tb.Particularly, the length that chained block LB is set is that a synchronization frame makes capture time Tb shorten usually, so the frequency band of PLL 14 is wide.Therefore, the length of hope chained block LB is set to two synchronization frame or more.Yet in the situation of the characteristic that guarantees PLL 14, length that can chained block LB is set to a synchronization frame.Be provided with to such an extent that surmount needed situation in the length with chained block LB, chained block LB relates to the recording capacity on the CD 2, so wish the length of chained block LB is arranged within 3 frames.
Then, explain the operation of only reproducing CD 2 of chained block insertion according to second embodiment as DVD-ROM.
Figure 12 is that explanation is at the synoptic diagram that inserts the situation of chained block as the recorded data on the DVD-ROM of CD and the boundary member between the additional data.
By the way, identical according to the functional-block diagram of the information recording/reproducer 1B of this distortion with functional-block diagram according to the information recording/reproducer 1 of first embodiment, thereby the explanation of omitting the functional-block diagram of information recording/reproducer 1B.
Promptly, shown in oblique line (hacures), chained block insertion parts 6B is inserted in chained block LB in two synchronization frames (the first synchronization frame SYF1 and the second synchronization frame SYF2) zone between the ECC piece of head of the last ECC piece of recorded data and new additional data.
Then, explain the data structure of the chained block LB that is applied to DVD-ROM with reference to Figure 12～Figure 14.
Figure 12 is the synoptic diagram of data structure that expression is applied to the chained block LB of DVD-ROM.As shown in figure 12, the chained block LB that is made up of two synchronization frames shown in the oblique line is inserted in the boundary member between ECC piece (n-1) and the ECC piece (n).
As shown in figure 12, similar first embodiment, the synchronous code SYX that is different from common synchronous code SY0～SY7, be added to the first synchronization frame SYF1 among the chained block LB of insertion by chained block insertion parts 6B, thereby the synchronous code SYY that is different from common synchronous code SY0～SY7, be added to the second synchronization frame SYF among the chained block LB of insertion, so, allow partly to distinguish chained block LB with reference to synchronous code SYX, SYY from real data.
In this structure, on two synchronization frame SYF1 in being included in chained block LB and the data division of SYF2, as shown in figure 12, the control information of record-playback action need replaces common data.
In this configuration, chained block LB is inserted in all boundary members between all contiguous ECC pieces on the CD 2.According to this configuration, when each new additional data of record on CD 2, chained block LB always is inserted between each recorded data and the additional data that each is new, and when comparing with the ECC piece that comprises 16 * 26 synchronization frames, chained block LB is in 3 synchronization frame sizes, and for example, 2 synchronization frames of size are more, the recording capacity of this feasible CD 2 of may avoiding waste, thus its recording capacity effectively utilized.
Yet, the invention is not restricted to structure at all boundary member insertion chained block LB.That is, chained block insertion parts 6B can insert chained block LB at every several boundary members.
Figure 13 is a display application in the synoptic diagram as the concrete data structure of the chained block LB of the DVD-ROM of CD 2.As shown in figure 13, the chained block LB that is made up of two synchronization frames is inserted in the boundary member between ECC piece (n-1) and the ECC piece (n).
When reproducing DVD-ROM, data recording unit 7 stops record data A1 in its rearmost end and carries out in the reproduction of ECC piece (n-1), so that move to chained block LB, thereby reads control information from chained block LB.When data recording unit 7 read the rearmost end that the position arrives chained block LB the time, data recording unit 7 begins to reproduce record data B1 at its head end from its ECC piece (n).
In to the reproduction of DVD-ROM operation, during synchronous code SYX in detecting chained block LB, the sign indicating number type of synchronous code SYX is different from the sign indicating number type of each synchronous code SY0～SY7, so, can easily distinguish the position of chained block LB.By the way,, may detect synchronous code SYY, still, in this embodiment, detect synchronous code SYX to distinguish chained block LB in order to distinguish chained block LB.
Then, explain control information on the chained block LB be recorded on the DVD-ROM.
Chained block LB is made up of two synchronization frames, and each synchronization frame size 91 byte, so chained block LB allows to write down the control information of maximum 182 bytes thereon.
Figure 14 (Figure 14 A and Figure 14 B) is according to the different examples of the form of the distortion of second embodiment, the control data of declare record on the chained block on the DVD-ROM.
In the form shown in Figure 14 A, control data comprises the synchrodata again of 5 byte lengths of the rearmost end of the odd and even data of 32 byte lengths of the control information of 145 byte lengths (size), corresponding control information and expression chained block LB.For example, control information comprises at least one address, the copy protection information of each ECC piece, the key information (key data) or the similar information of decoding scrambler data needs.
Then, in an embodiment because chained block is formed on all boundary members between the ECC piece located adjacent one another, but record controls information so that corresponding each ECC piece, permission will be applied to the various Copy Protection methods of each ECC piece.As an example of Copy Protection method, different copy information items is set to the control information of its each corresponding each ECC piece, can prevent to copy the record data on the selected specific region.In addition, corresponding each ECC piece of each control information item is set, so, according to the posting field that writes down the ECC piece respectively, can change the Copy Protection method of determining by each control information item.
The ECC piece is provided with different scrambler key (scramble key) respectively, makes the decoding of scrambler data in the ECC piece become difficult, thereby improved the performance of scrambler processing and effectively prevented illegal copies.
In the form shown in Figure 14 B, control data comprises the control information of 55 byte lengths (size) and the odd and even data of 32 byte lengths, is recorded in each the zone of synchronization frame (sink) SYF1 of each 91 byte-sized and corresponding chained block LB and SYF2.Control information also comprises dummy argument data and the synchrodata again on each each rearmost position that is recorded in two synchronization frame SYF1 and SYF2.In the form shown in Figure 14 B, the content of control information is identical with content in the control information of the form shown in Figure 14 B in fact.In addition, in the form shown in Figure 14 B, twice identical control data of duplicate record can improve the reliability of control data on chained block LB.
About the information reproduction apparatus that is used to reproduce DVD-ROM of distortion comprises: comprise and the information reproduction apparatus of optical pick-up 3, reproducing signal production part 11, scale-of-two amplitude limit parts 12, PLL 14, holding signal production part 15, data read parts 16, CPU 20 and storer 21 components identical, so can detect chained block LB as mentioned above.
Yet, in the situation that reads control data from chained block LB, for when reproducing DVD-ROM on chained block LB the reproducing control data, reproduce the control data on the chained block, and do not use holding signal from holding signal production part 15.
As mentioned above, information recording/reproducer 1A/1B according to second embodiment, but form chained block at the record of corresponding DVD form/can heavily write down DVD-RW/DVD-R or the boundary member that only reproduces between the contiguous ECC piece on the DVD-ROM, can guarantee the compatibility of its record format.In addition, the synchronous code SYX that will have a special style is added to chained block.
This configuration allows not form chained block in each ECC piece, prevents the error-correcting performance deterioration, and avoids whole ECC piece can not be used for record data.Use data division as the chained block enough shorter, allow to reduce the capacity of wasting in the video disc recording capacity than ECC piece.
In addition, when reproducing CD, detect the position that synchronous code SYX allows to discern reliably chained block.
And, the plating zone of being made up of the recessed district of plating line is formed on the chained block of DVD-RW/DVD-R, and control data is recorded on the chained block of DVD-ROM, so, when with the copying data on the DVD-ROM during to DVD-RW/DVD-R, the position of the control data of DVD-ROM is overlapping on the plating zone on the DVD-RW/DVD-R, and thus, the recessed district of plating line is to the feasible reproducing control data that are difficult to of the interference of record mark.For example, the situation on the copy protection information of corresponding each ECC piece or chained block that key data is recorded in DVD-ROM may be distinguished copy protection information or key data on DVD-RW/DVD-R, has strengthened the effect that stops illegal copies.
By the way, in first embodiment and second embodiment, the present invention is applied to the information recording/reproducer of corresponding DVD form, but the invention is not restricted to this application.
That is, the present invention can be applicable to the corresponding information recording/reproducer that allows to form the recoding/reproduction form of chained block on CD.
