Description

Has information recording method with the interchangeability of read-only medium

Technical field

The present invention relates to DVD-dual layer+RW rewritable multi-layered information recording mediums such as (Digital Versatile Disc+Rewritable) is information recording method, information record carrier, information record program and the storage medium of the object of information record.

Background technology

But coil the once DVD+R of once-type DVD dish or the DVD+RW of rewriting type DVD dish etc. as recordable type DVD, these dishes are the recordable type DVD dishes that have high reproduction interchangeability with the read-only DVD dish of single-surface single-layer.Extensively carry out for the high speed of such recordable disc, the research and development of high capacity.

One of them has the read-only DVD dish (hereinafter to be referred as making ' DVD-dual layer ') of single-surface double-layer.Exist the track of the second layer and ground floor similarly from the frontlighting path mode (Parallel Track Path mode=PTP mode) in week outward of interior week in the DVD-dual layer, and the track of the second layer is from the backlight path mode (Opposite Track Path mode=OTP mode) of periphery towards interior week.In the PTP mode, the radial location of the address that the data area of the ground floor and the second layer begins equates, all is from physical address 30000H.In addition, derive (lead-out) zone in the configuration of the rear of data area.In the OTP mode, the radial location of the address that the data area of the second layer begins equates that with the radial location of the address that finish the ground floor data area physical address of the starting position, data area of the second layer is for having carried out the end address, data area of ground floor the address of bit reversal.Size in the data area of the ground floor and the second layer exists under the situation of difference, and this difference zone becomes the export area.For example, in the PTP dish, end address, the data area D2 of the end address D1 of the data area of ground floor and the second layer is under the situation of D1＞D2, and difference region D 1-D2 becomes the export area.Like this, the zone that records data in a recording layer also records data in the zone of second layer correspondence.This is for fear of for example when the user reproduces the data of ground floor, under the focus that reads laser in the tracking (seek) of destination address converges to situation on the second layer once in a while, do not record data on the second layer of same radial location then can not obtain rough sledding such as address information if be created in, its result, generation can not be reproduced the problem of the data of ground floor.

On the other hand, also in the research and development that extensively are used for high speed, high capacity, one of them has the DVD+R dish (hereinafter to be referred as making ' DVD-dual layer+R ') that has with the single-surface double-layer of the reproduction interchangeability of DVD-dual layer for recordable information recording carrier.The recording capacity of DVD-dual layer+R is 8.4Gbyte, data capacity with respect to existing individual layer DVD+R is 4.7Gbyte, have roughly 2 times recording capacity, DVD player or the DVD-ROM driver of the reproduction that the data that write down can be by can carrying out DVD-dual layer are read.

Summary of the invention

Here, the logical address among DVD-dual layer+R is assigned with continuously from the start address of the data area of ground floor, logical address from the end address, data area of ground floor continuously to the data area start address of the second layer.In other words, carry out under the situation of data recording continuously the user, from the data area start address opening entry of ground floor, after record till the end address, data area of ground floor was finished, then the data area start address from the second layer carried out record.Like this, in DVD-dual layer+R record, the user can write down and not can be appreciated that recording layer.Therefore, consider that user's data is recorded in not the writing down the second layer midway or fully of data area of the second layer and situation about finishing.For example, become following dish design, promptly with the data area of the second layer midway, be to exist the state of posting field not to be through with under the situation of user's data record in the data area of the second layer, in the data area of the second layer, remain under the state of posting field not and the read-only non-exchange of DVD-dual layer dish.In addition, for example when the user reproduces the data of ground floor, under the focus that reads laser in the tracking of destination address converges to situation on the second layer once in a while, do not record data on the second layer of same radial location then can not obtain rough sledding such as address information if be created in, its result, generation can not be reproduced the problem of the data of ground floor.Under the situation of such rough sledding end user data recording not writing down the second layer fully too.

This respect, about DVD-dual layer+R following scheme has been proposed, thereby, and guarantee read (unexposed) by a read driver promptly by with the dummy data that for example has the user data attribute or derive the not posting field that writes down the second layer and obtain exchange in logic with the DVD-dual layer dish.But, under the situation of this motion example, under the state that is through with fully of record, can obtain the interchangeability with the DVD-dual layer dish, but under record state midway, can not obtain interchangeability with the DVD-dual layer dish.

In addition, for example,, proposed the data area is divided into the scheme (unexposed) that a plurality of sections (session) write down about DVD-dual layer+R.In the device of such motion example, in primary data area, write down under the situation of 1 section, in existing individual layer DVD+R, by carrying out data recording with section unit, can guarantee to exchange, and in DVD-dual layer+R, can not guarantee to exchange by the reproduction of a read driver by the reproduction of a read driver.This is owing to be arranged in and the data area of the second layer of the same radius of posting field of ground floor record data not.

Owing to DVD-dual layer+R is that the write-once discs that can not carry out the rewriting of data causes such problem.That is, under the state that record does not finish fully, during by the not posting field of the record second layers such as dummy data, data are written in the record that then carries out, and produce the rough sledding that the data that write down can't be read out.

The objective of the invention is to make in operation of recording for information recording carrier with a plurality of recording layers, record be not through with fully state, promptly under midway the state of record, also can keep interchangeability with read-only disk.

The invention of claim 1 record is that the information recording carrier with rewritable a plurality of recording layers is carried out record, these a plurality of recording layers have the information recording method of the data area that is used for user data respectively, comprise: posting field has or not determining step, judges whether there is posting field in the data area at least of first recording layer; And correspondence posting field data filling step not, in described first recording layer, exist under the situation of described posting field, for except in second recording layer of this first recording layer, be equivalent to not posting field in the zone of same radial location, the regulation time recording predetermined data before finishing with described posting field for the record of described information recording carrier.

Thereby, basically can carry out the rewriting of data, with the such information recording carrier of the DVD-dual layer+RW with a plurality of recording layers is object, not posting field for the second layer corresponding with the posting field of ground floor, carry out record in predetermined timing, even thereby, also can guarantee to exchange by the reproduction of a read driver to the uncompleted state of the record of this medium.For example, in rewritable DVD-dual layer+RW dish under ground floor has write down data conditions, the data that are being equivalent to recording prescribed in the data area with the second layer of the same radial location of posting field of ground floor in predetermined timing, thereby, even record state midway, also can guarantee to exchange, and can guarantee normally to read by read-only DVD driver with the logic of second layer DVD.

The invention of claim 2 record in the information recording method of claim 1 record, by described correspondence not posting field data filling step described predetermined data that described not posting field is write down be dummy data with user data characteristic.

Thereby, have the predetermined data of the dummy data of user data attribute as the not posting field of filling regulation by utilization, as predetermined data, be not restricted to derivation (Lead-out) etc., and can obtain dirigibility as predetermined data, and derive (Lead-out) and itself can use for the purpose of the end address of stipulating this recording layer, comprise dummy data, can be made as state near common user data record.

The invention of claim 3 record in the information recording method of claim 1 record, by described correspondence not posting field data filling step described predetermined data that described not posting field is write down be to derive (derivation).

Thereby, enlarging the predetermined data of utilizing the not posting field of making to fill regulation by being recorded in derivation (Lead-out) behind the data area originally, can realize simply.

The invention of claim 4 record in the information recording method of claim 1 record, by described correspondence not posting field data filling step described predetermined data that described not posting field is write down be to represent Unrecorded logical erase pattern in logic.

In rewritable CD-RW etc., carry out under the situation of wiping of posting field, be not physically to return not recording status, but carry out record with the logical erase pattern (pattern) that is wiped free of on the presentation logic.Is posting field not with the zone of logical erase mode record for the information record carrier that can discern this pattern, but is posting field for the existing drive assembly that can not discern this pattern.Therefore, carry out record by the not posting field to the second layer with the logical erase pattern, can guarantee to exchange by the reproduction of a read driver, the information record carrier that can discern this pattern simultaneously can keep the Unrecorded state of the second layer on medium.

The invention of claim 5 record in the information recording method of any one record of claim 1 to 4, by described correspondence not posting field data filling step described predetermined timing that described not posting field is write down be the moment of receiving the discharge request of described information recording carrier from the user.

Thereby, can guarantee to exchange owing to fill the record of the predetermined data of posting field not, so after carrying out data recording by information record carrier, this medium is recorded in the moment that is discharged from and gets final product by the reproduction of a read driver.

The invention of claim 6 record in the information recording method of any one record of claim 1 to 4, by described correspondence not posting field data filling step described predetermined timing that described not posting field is write down be to the moment after the data recording of the described posting field of described first recording layer.

Thereby, be not limited to receive the moment that medium is discharged request, under situation about being carried out, also can follow requested data and be recorded in and these data of recording prescribed in not posting field in other recording layer on same radial location of posting field from user's data record.In this case, each record performance descends, but for example compares with the situation of claim 5, and medium is discharged and handled the required time is to get final product the short time.

The invention of claim 7 record is in the information recording method of any one record of claim 1 to 4, with the information recording carrier that writes down by the multi-region section is object, by described correspondence not posting field data filling step described predetermined timing that described not posting field is write down be to receive the moment that finishes (session close) request from user's section.

At the information recording carrier that writes down by the multi-region segmented mode, finishing section and writing down the purpose that imports and derive in the front and back of record data is to exchange in order to ensure the reproduction by a read driver.In other words, only need with the situation of the exchange of a read driver under finish section, under situation about not needing with the exchange of a read driver, do not carry out section and finish and in same section, write afterwards data.Thereby, have at information recording carrier under the situation of a plurality of recording layers also that the data of recording prescribed get final product when section finishes.Like this, being under the situation of object,, only under situation about need exchange with the reproduction of a read driver, can guarantee to reproduce and exchange by the data of recording prescribed when section finishes with the information recording carrier that writes down by the multi-region segmented mode.In addition, do not needing to reproduce under the situation of exchange, can prevent that the performance that the specified data record causes from reducing.

The invention of claim 8 record in the information recording method of any one record of claim 1 to 4, by described correspondence not posting field data filling step described predetermined timing that described not posting field is write down be during not from user's medium accesses request.

For example, in the DVD+RW of rewritable DVD dish, adopt the backstage format, i.e. the format of carrying out carrying out before writing down from user's data on the backstage is handled.In the backstage format,, only (initial treatment) part of ingress area and come user notification format to finish,, carried out record with dummy data in remaining areas less than time from user's access by record for formatted requests from the user.Thereby predetermined data record can be in that the time from user's medium accesses carry out on the backstage yet.Like this, by in that the time from user's medium accesses is not carried out the predetermined data record on the backstage, for example compare with described claim 5,7, can shorten the time that medium is discharged or the section end is required, and, owing in from user's record, do not carry out the predetermined data record, therefore for example compare with claim 6, can prevent the reduction of record performance.

The invention of claim 9 record is in the information recording method of claim 8 record, has the operation of recording interrupt step, in record, have under the situation from user's medium accesses request, interrupt the operation of recording of this specified data for the described specified data of described not posting field.

Thereby, can carry out for the predetermined data operation of recording of posting field not and can not bring obstacle original access action.

The invention of claim 10 record is in the information recording method of claim 1 record, has the backstage formatting step, carry out on the backstage handling for the format of described information recording carrier, by described correspondence not posting field data filling step described predetermined timing that described not posting field is write down be the moment of in handling, receiving from user's the formative interrupt request in backstage for the format of described information recording carrier.

For example, in the format of the backstage of DVD+RW, even format state midway also can take out medium.In DVD+RW, when taking out, medium carries out the formative Interrupt Process in backstage temporarily, in this Interrupt Process, under the situation that will obtain with the exchange of existing read-only DVD driver, the not posting field between posting field of record becomes by after the continuous recording state with the dummy data record discontinuously on medium, from the interim derivation of final address record of posting field.Here, the information recording carrier with a plurality of recording layers is being carried out also considering to take out medium midway in this format in the formative information record carrier in backstage.At this moment, in order to guarantee to exchange, except the situation with DVD+RW is the format Interrupt Process of example narration, also need other the not posting field of recording layer is carried out the record of predetermined data with the reproduction of a read driver.Thereby,,, also can keep exchanging taking-up dish simultaneously by the reproduction of a read driver in this format even the information recording carrier with a plurality of recording layers is being carried out under the formative situation in backstage according to the present invention midway.

The invention of claim 11 record is in the information recording method of claim 1 record, has the backstage formatting step, the data area of described a plurality of recording layers is divided into a plurality of zones respectively, between a plurality of recording layers, alternately carry out record for these cut zone, thereby carry out handling for the format of described information recording carrier on the backstage.

Usually, in backstage format, carry out the record of dummy data in the medium week continuously.Thereby, in the invention of the information recording carrier with a plurality of recording layers being carried out formative claim 10 record in backstage, also suppose from being assigned with the first recording layer opening entry dummy data of minimum logical address, carry out the dummy data record of next record layer in the moment that the format of this recording layer has been finished.But, in the such record order in the format of backstage, consider in format to keep taking out medium simultaneously by the exchange of a read driver midway, then produce the time consuming rough sledding of the formative Interrupt Process in backstage.This is to need to carry out the predetermined data record owing to reckoning without in the format Interrupt Process.For example, data area for described first recording layer, format under the situation of interruption under the state that dummy data record that format causes has been finished at Zone Full roughly, in order to keep exchange, also have to write down roughly Zone Full with described specified data for other the data area of recording layer by a read driver.This respect, as the present invention, in the dummy data record in the format of backstage, with the data area of a plurality of recording layers by each cut zone record that hockets, thereby under the situation that the format interrupt request is arranged, can reduce the zone of recording prescribed data, and can finish the format Interrupt Process with the short time.

The invention of claim 12 record is in the information recording method of any one record of claim 1 to 11, and described information recording carrier is the information recording carrier of compound DVD+RW standard.

Thereby can be applied to well with the information recording carrier is the situation of object, and this information recording carrier meets in the DVD+RW standard that becomes problem aspect the interchangeability of the read-only information recording carrier with the recording layer that has a plurality of not recording areas.

The effect of the information recording method of these claim 1 to 12 records, effect also can realize by the information record carrier of claim 13 to 24 record, the information record program of claim 25 record, the storage medium of claim 26 record.

According to the present invention, can carry out the rewriting of data, with the information recording carrier with a plurality of recording layers is object, carry out record in predetermined timing with the not posting field of the predetermined data pair second layer corresponding, so to the uncompleted state of the record of this medium, promptly record also can guarantee to exchange by the reproduction of a read driver midway with the posting field of ground floor.

This optical disc apparatus 1 comprises: be used to rotate spindle motor 3, optical take-up apparatus 4, laser control circuit 5, motor driver 6, reproducing signal treatment circuit 7, servo controller 8, buffer RAM 9, buffer-manager 10, interface 11, ROM12, CPU13 and the RAM14 etc. of driving as the CD 2 of information recording carrier.In addition, the arrow shown in Fig. 1 is represented flowing of representational signal or information, does not represent annexation whole of each piece.

In more detail, at first,, be that the DVD+RW (hereinafter to be referred as making ' DVD-dual layer+RW ') with the single-surface double-layer that meets the DVD+RW standard is the example application of the situation of record object as CD 2.

Optical take-up apparatus 4 comprises: as the semiconductor laser of light source; Optical system comprises object lens, is used for the laser aiming that will penetrate from this semiconductor laser record surface to CD 2, will be directed to the light-receiving position of regulation by the back light of record surface reflection simultaneously; Optical receiver is configured in the light-receiving position and receives back light; And drive system (focus actuator, tracking actuator, tracking motor etc.) (all not shown) etc.The electric current corresponding with the light-receiving amount is output to reproducing signal treatment circuit 7 from optical receiver.

Servo controller 8 generates the control signal of the focus actuator be used to control optical take-up apparatus 4 based on focus error signal, generates the control signal of the tracking actuator that is used to control optical take-up apparatus 4 simultaneously based on tracking error signal.These control signals are outputed to motor driver 6 from servo controller 8.

Motor driver 6 drives the focus actuator of optical take-up apparatus 4 and follows the tracks of actuator based on the control signal from servo controller 8.In addition, motor driver 6 is controlled spindle motor 3 according to the indication of CPU13, makes that the linear velocity of CD 2 is certain.And then motor driver 6 drives the tracking motor that is used for optical take-up apparatus 4 based on the indication of CPU13, and optical take-up apparatus 4 is moved along the target track of radial direction to CD 2.

Interface 11 is and the main frame that becomes external device (ED) (for example, PC) two-way communication interface.

CPU13 and ROM12, RAM14 together constitute the microcomputer (computing machine) that this optical disc apparatus 1 has.In the ROM12 that also works, store the program that comprises the information record program of recording and narrating with the scrutable code of CPU13 as described later as storage medium.CPU13 will control required data etc. simultaneously and be kept among the RAM14 temporarily according to the action that is stored in the programmed control each part mentioned above among the ROM12.In addition, during the power connection of this optical disc apparatus 1, the program that is stored among the ROM12 is written into (installation) in the primary memory (not shown) of CPU13.

In the present embodiment, be characterised in that as the DVD-dual layer+RW of the CD 2 of object this optical disc apparatus 1 is mounted and has from the recording processing control under the situation of the record request of the user data of host computer side, but before this explanation, design that the read-only DVD of the prerequisite of the standard that becomes DVD+RW coils etc. be described.

At first, Fig. 2 A～2B represents the design example of read-only DVD dish.Fig. 2 A represent single-surface single-layer (Single Layer) dish (below, be called ' single-layered disk ') situation, Fig. 2 B represent the single-surface double-layer (Dual Layer) of PTP mode dish (below, be called ' PTP dish ') situation, Fig. 2 C represents the situation of the dish (below, be called ' OTP dish ') of the single-surface double-layer of OTP mode.

The DVD dish has the information area (InformationArea) that is made of ingress area (Lead-in Area), data area, export area (Lead-outArea) basically, under the situation of single-layered disk and PTP dish, has information area in each recording layer.OTP dish is made of an information area, has zone line (Middle Area) at the rear of the data area of each recording layer.The layer 0 of the layer 0,1 of single-layered disk and PTP dish and OTP dish carries out the reproduction of data, layer 1 reproduction from the inside Zhou Jinhang data of periphery of OTP dish from interior circumferential periphery.Each recording layer of one deck dish and PTP dish is assigned with continuous physical address (Physical Sector Number) from the ingress area to the export area.On the other hand, under the situation of OTP dish, 0 zone line is assigned with continuous physical address from the ingress area to the layer, but the physical address of layer 1 is assigned with the address of the physical address of layer 0 having been carried out bit reversal, heavy zone line is to the export area, and physical address constantly increases.In other words, the start address of the data area in the layer 1 is for having carried out the end address in the layer 0 address of bit reversal.

Shown in Fig. 2 B, ingress area in the PTP dish begins and the end address of the start address of end address, data area and export area in same radial location, also have the export area start address, be that the end address of data area is for all different situation of each recording layer.Under the different situation in the end address of data area, this difference zone is recorded derivation.

On the other hand, shown in Fig. 2 C, under the situation of OTP dish, the beginning of the data area start address of the end address, data area of the start address of ingress area and the end address of export area, layer 0 and layer 1 and the zone line of each recording layer and end address are in same radial location, and the data area start address of layer 0 is not necessarily consistent with the end address, data area of layer 1.Also this difference regional record there is derivation under the situation of OTP dish.

In the information recording method for the present embodiment of the DVD-dual layer+RW (CD 2) of for example OTP mode of the design that meets so read-only DVD dish, with reference to Fig. 3 A, 3B explanation predetermined data example etc.In the present embodiment, carry out the backstage format, in the format of backstage, carry out from the user's data record for CD 2.

At first, Fig. 3 A is illustrated in the state that carries out data recording in the format of backstage.In the format to the CD 2 of present embodiment, after a part that has write down ingress area (layer 0), format is finished to user notification.After notice is finished in format, then carry out the record of data area on the backstage.Under by situation from user's record request, interrupt the backstage format, carry out record to the zone of request.Here, as shown in Figure 3A, suppose that the user coils discharge under the state that has carried out data recording from the address B on the CD 2 to E.

Dummy data record under the situation that Fig. 3 B represents to interrupt the backstage format and coil discharge.Coiling under the situation of discharge, the user formats interrupt request to optical disc apparatus 1.In the format Interrupt Process, at first with on the CD 2 discontinuously the interregional not posting field of record with dummy data record and become by continuous recording state.But, in the present embodiment, because user data by record continuously, is therefore skipped this processing.Then, will with the data area of layer 0 in the dummy data (Dummy Data) of not posting field (from address E ' to B ') usefulness user data attribute of layer 1 of the same radial location in zone (from address B to E) that writes down, for example, all use 0 data recording.Here, B ' and E ' are respectively the values of B and E having been carried out bit reversal.In addition, at this moment, write down interim zone line (Temporary Middle Area) at the rear of address E and the place ahead (peripheral direction) of address E ', record is derived and also can in the export area.

Thereby, according to present embodiment, basically can carry out the rewriting of data, the CD 2 such with the DVD-dual layer+RW with a plurality of recording layers is object, not posting field for layer 1 (second layer) corresponding with the posting field of layer 0 (ground floor), carry out record in predetermined timing, thereby, also can guarantee to exchange by the reproduction of a read driver even to the uncompleted state of the record of this CD 2.Promptly, in DVD-dual layer+RW dish, write down under the data conditions at layer 0, the data that are being equivalent to recording prescribed in the data area with the layer 1 of layer 0 the same radial location of posting field in predetermined timing, even thereby record state midway, can guarantee to exchange, and can guarantee normally to read by read-only DVD driver with the logic of DVD-dual layer.In this case, have the specified data of the dummy data of user data attribute as the not posting field of filling regulation by utilization, be not restricted to derivation (Lead-out) etc., and can obtain dirigibility as predetermined data, and derive (Lead-out) and itself can use for the purpose of the end address of stipulating this recording layer, comprise dummy data, can be made as state near common user data record.

In the information recording method for DVD-dual layer+RW (CD 2), with reference to Fig. 4 A, 4B explanation other embodiment relevant with the predetermined data example.In the present embodiment, be assumed to be by the multi-region segmented mode CD 2 is carried out recording mode.In addition, here, application is as the multi-region segment record mode of the DVD+R of write-once type DVD dish, record imports (according to the multi-region segment record of DVD+R before user data area, the importing that second section is later is called introducing (Intro)), record is derived (equally the derivation before the last section being called end (closure)) at the rear of user data area.

Fig. 4 A represents to record in first section data (from address B to E) state, under this state, supposes to receive the request that section finishes from the user.

Fig. 4 B represents the derived record in the section end.In the section end process, at first, with the not posting field of the layer 1 of the same radial location in the zone of having write down in the data area of deriving (Lead-out) record and layer 0 (from address B to F) (from address F ' to B ').Then, record ingress area, the data area of having write down in the following layer 0 (from address B to E) end of record (EOR) (Closure) (from address E to F).And then, in layer 1, for from address F ' to E ' and the export area all write down derivation.Here, B ', E ' and F ' are made as the value of B, E and F having been carried out bit reversal.In the present embodiment, cut apart the derived record of having carried out in the layer 1, but also can continuous recording.

In addition, under the state shown in Fig. 4 B (layer 1 all is to derive, and does not have zone line etc.), do not obtain closely with the logic of DVD-dual layer and exchange, but not the state that only in layer 0, has write down data at least, therefore can be by the read-only DVD driver data of readout layer 0 normally.Therefore the CD 2 of present embodiment can carry out overriding of data, is recorded as to obtain the form that exchanges with the logic of DVD-dual layer in the moment that data recording is through with fully and get final product.

Thereby, under the situation of present embodiment, also as Fig. 3 A, the illustrated situation of 3B is same, in DVD-dual layer+RW dish, in layer 0, write down under the data conditions, should be in predetermined timing, in the data that are equivalent to the data area recording prescribed of the layer 1 of layer 0 the same radial location of posting field, even thereby record state midway, also can guarantee to exchange with the logic of DVD-dual layer, and can guarantee normally to read by read-only DVD driver, but enlarge the predetermined data of utilizing the not posting field of making to fill regulation by being recorded in derivation (Lead-out) behind the data area originally, can realize simply.

In the information recording method for DVD-dual layer+RW (CD 2), with reference to Fig. 5 A, 5B explanation other embodiment relevant with the predetermined data example.In the present embodiment, same with the situation of Fig. 4 A, 4B explanation, suppose CD 2 to be carried out record with the multi-region segmented mode.

Fig. 5 A represents to record in first section data (from address B to E) state, under this state, supposes to receive the request that section finishes from the user.

Fig. 5 B represents the logical erase mode record in the section end.In the section end process, at first, with the not posting field of the layer 1 of the same radial location in the zone of having write down in logical erase mode record and layer 0 the data area (from address B to F) (from address F ' to B ').Then, record ingress area, the data area of having write down in the following layer 0 (from address B to E) end of record (EOR) (Closure) (from address E to F).And then, in layer 1, for from address F ' to E ' and the export area all write down the logical erase pattern as predetermined data.Here, B ', E ' and F ' are made as the value of B, E and F having been carried out bit reversal.In the present embodiment, cut apart the logical erase mode record that has carried out in the layer 1, but also can continuous recording.In addition, the export area also can be write down derives rather than the logical erase pattern.

In addition, under the state shown in Fig. 5 B (derive, do not have zone line etc.), do not obtain closely with the logic of DVD-dual layer and exchange, but not the state that only in layer 0, has write down data at least, therefore can be by the read-only DVD driver data of readout layer 0 normally.Therefore this information recording carrier can carry out overriding of data, is recorded as to obtain the form that exchanges with the logic of DVD-dual layer in the moment that data recording is through with fully and get final product.

Carrying out under the situation of wiping of posting field in rewritable CD-RW etc., is not physically to return not recording status, but carries out record with the logical erase pattern that expression in logic is wiped free of.Is posting field not with the zone of logical erase mode record for the optical disc apparatus that can discern this pattern, but is posting field for the existing drive assembly that can not discern this pattern.Therefore, as present embodiment, carry out record by the not posting field to the second layer with the logical erase pattern, can guarantee to exchange by the reproduction of a read driver, the optical disc apparatus 1 that can discern this pattern simultaneously can keep the Unrecorded state of the second layer on medium.

In the information recording method for DVD-dual layer+RW (CD 2), with reference to the embodiment of the timing controlled example of Fig. 6 declare record predetermined data.In the present embodiment,, suppose that from user's record from the data area start address of layer 0 record continuously, only layer 0 is recorded data when dish is discharged request in order to simplify processing.

At first, when handling beginning (step S1), judge the record request (S2) that whether has from the user.Under having (S2 ' being '), carry out record (S3) to the zone of request from the situation of user's record request.Under not from the situation of user's record request (S2 ' denying '), the processing of skips steps S3.Then, judge the dish discharge request (S4) that whether has from the user.On the other hand, under the situation that the request of discharging from user's dish is arranged (S4 ' being '), the posting field (S5) in the detection layers 0.The processing of this step S5 can be used as that posting field has or not determining step, posting field has or not decision means, posting field has or not arbitration functions to carry out.

At this moment, at hypothetical layer 0 is under the situation of posting field from address A to B, arrive A ' (S6) as specified data with the dummy data (Dummy Data) of user data attribute or the address B ' of derivation (Lead-out) or logical erase mode record layer 1, discharge CD 2 (S7), end process (S8).The processing of step S6 can be used as correspondence not posting field data filling step, correspondence not posting field data filling component, correspondence not the posting field data fill function and carry out.

In addition, in the present embodiment, do not consider ingress area (layer 0) and export area (layer 1) and zone line (layer 0,1) especially, but can when dish is discharged, write down each zone yet.

Thereby, be used to guarantee that the reproduction by a read driver exchanges owing to fill the record of the specified data of posting field not, so by step S6 to the predetermined timing of the record of posting field not as present embodiment, after in this optical disc apparatus 1, carrying out data recording, if receive moment (step S5) of discharge request of this CD 2 from the user just enough.

In the information recording method for DVD-dual layer+RW (CD 2), with reference to other embodiment of the timing controlled example of Fig. 6 declare record predetermined data.In the present embodiment, same with the situation of Fig. 6, in order to simplify processing, suppose that from user's record from the data area start address of layer 0 record continuously, when dish was discharged request, only layer 0 recorded data.

At first, when handling beginning (step S11), judge the record request (S12) that whether has from the user.Under having (S12 ' being ') from the situation of user's record request, carry out record (S13) to the zone of request after, write down (S14) in the zone of the layer 1 of the same radius of posting field to being positioned at this.The processing of step S12, S13 is as posting field has or not determining step, posting field has or not decision means, posting field has or not arbitration functions to carry out, the processing of step S14 as correspondence not posting field data filling step, correspondence not posting field data filling component, correspondence not the posting field data fill function and carry out.Under not from the situation of user's record request (step S 12 ' denying '), the processing of step S13, S14 is skipped.Then, judge whether to discharge request (S14) from user's dish.If dish is not discharged request (S14 ' denying '), wait for record request (S12) once more from the user.On the other hand, under the situation that the request of discharging from user's dish is arranged (S14 ' being '), discharge dish (S17), end process (S8).

In the present embodiment, do not consider the record of ingress area (layer 0), export area (layer 1) and zone line (layer 0,1) especially, but can when dish is discharged, write down each zone yet.

Like this, according to present embodiment, having under the situation of record request, for each record is positioned at and the not posting field of the layer 1 of the same radius of posting field, compare with the method for Fig. 6,, discharge processing of request but can improve for dish for the performance reduction of each record request.

In the information recording method for DVD-dual layer+RW (CD 2), with reference to other embodiment of the timing controlled example of Fig. 8 declare record predetermined data.In the present embodiment, use the multi-region segment record of the DVD+R that coils as write-once type DVD for the record of rewritable DVD-dual layer+RW, before user data area, according to the multi-region segment record that imports (DVD+R), introduce (Intro) at the importing record that second section is later, be recorded in the rear (equally the derivation before the final section being called end (Closure)) of user area.In addition, as the logical erase pattern shown in specified data hypothetical record Fig. 5 A, the 5B.And then, same with the situation of Fig. 6, in order to simplify processing, suppose from user's record from the data area start address of layer 0 record continuously, suppose when section finishes only layer 0 record data.

At first, when handling beginning (step S21), judge the record request (S22) that whether has from the user.Under having (S22 ' being '), carry out record (S23) to the zone of request from the situation of user's record request.Under not from the situation of user's record request (step S22 ' denying '), the processing of step S23 is skipped.Then, judge whether section ending request (S24) from the user.If there is not section ending request (S24 ' denying '), judge the dish discharge request (S29) that whether has from the user once more.If dish is not discharged request (S29 ' denying '), wait for record request (S22) once more from the user.Repeat the above processing line data record of going forward side by side, but proceed to the moment of the position shown in Fig. 5 A here in data recording, suppose to have section ending request (S24 ' being ') from the user.In this case, shown in Fig. 5 B, at first, record ingress area (layer 0) (S254) is followed end of record (EOR) (layer 0) (S26).Then, obtain the posting field (S27) of layer in 0.In the example of Fig. 5 A, 5B, A is recorded to F from the address.The processing of step S27 is as posting field has or not determining step, posting field has or not decision means, posting field has or not arbitration functions to carry out.Then, write down (S28) with the zone in the layer 1 of the same radial location of posting field in logical erase pattern pair and the layer 0 (from address F ' to A ').The processing of step S28 as correspondence not posting field data filling step, correspondence not posting field data filling component, correspondence not the posting field data fill function and carry out.It more than is the section end process.Then, confirm whether to have dish to discharge request (S29), having dish to discharge under the situation of request (step S29 ' being ') discharge dish (S30), end process (S31) from the user.If dish is not discharged request (S29 ' denying '), wait for record request (S22) once more from the user.Here, there is situation to become new record to section from user's record request.On the other hand, not from user's section ending request, have dish to discharge under the situation of request in step S29 in step S24, the user does not need to exchange by the reproduction of read-only DVD driver, skip processing, with the state discharge dish of Fig. 5 A from step S25 to step S28.

In the information recording method for DVD-dual layer+RW (CD 2), follow the backstage to format the embodiment of handling with reference to Fig. 9 A～9F and Figure 10 explanation.The summary of present embodiment is described, DVD-dual layer+RW (CD 2) is formatd by the backstage, and in this format, receive under the situation from user's record request, interrupt format and handle the line data record of going forward side by side.In addition, specified data to layer 1 writes down as the formative dummy data record in backstage, do not carrying out under the situation of taking inventory the request of getting from the user, in the specified data record, having under the situation from user's record request, interrupting the record that the specified data record also carries out user's request.In addition, shown in Fig. 9 A, N is carried out in the data area cut apart, to each cut zone alternately recording layer 0, layer 1 by the formative dummy data in backstage record.Under situation about having from user's format interrupt request, the specified data record in the complete layer 1 writes down interim zone line, derivation.In addition, for the purpose of simplifying the description, suppose that record from the user is the address in the layer 0.

Fig. 9 A represents DVD-dual layer+RW (CD 2) has been begun formative state.Dotted line among the figure represents each recording layer is carried out continuously the record unit of dummy data record.In backstage format, only (initialization process) part of ingress area by record, become possibility from user's record.

Fig. 9 B has represented to write down the state of the data of user's request.In backstage format, have under the situation from user's record request, interrupt format and handle (dummy data record) and write down the data that have been requested.

Fig. 9 C is illustrated in and begins the formative state in backstage again after the user data record is finished.Dummy data record in the backstage format is to the cut zone of each regulation alternately recording layer 0 and layer 1.Here, do not carrying out the specified data record under the situation from user's access request, but the dummy data record in handling as format substitutes other function here.

The specified data that Fig. 9 D is illustrated in layer 1 writes down the state of receiving in (the dummy data record in the format) from user's record request.In Fig. 9 C, under the situation that the dummy data record of regulation in format record unit has been finished, with the zone of the journal next record unit of layer 0, layer 1.Here, in dummy data recording layer 1, receive under the situation from user's record request the data recording of interrupting the dummy data record and being requested.

Fig. 9 E is illustrated in the state that begins specified data record (the dummy data record in the format) after the user data record is finished again.

Fig. 9 F represents to receive the state from user's format interrupt request.In format was interrupted, at first write down than the not posting field of this zone near week in being present in dummy data in the final entry zone in the detection layers 0.Here, with the zone of dummy data recording layer 1.After dummy data record in the data area was finished, then interim zone line was write down in final entry zone (peripheral direction), and then record is derived in the export area.

In addition, as the predetermined data record, in the present embodiment, the dummy data record as in the format processing of backstage substitutes other processing, but in not carrying out the formative pen recorder in backstage, also can carry out the predetermined data record on the backstage.

Here, with reference to the general flowchart explanation processing controls example relevant shown in Figure 10 with such operation of recording.Here, suppose the predetermined data of layer 1 is write down as the formative dummy data record in backstage, do not carrying out under the situation of taking inventory the request of getting from the user.In addition, for the purpose of simplifying the description, suppose that record from the user is the address in the layer 0.

At first, under having (S41) from the situation of user's formatted requests, the part (S42) of record ingress area, and to user notification (S43) finished in format, beginning backstage format (S44).The dummy data record of the data area in the format of backstage is called deicing (De-ice).Can carry out data recording randomly from the user after the format beginning of backstage.Then, judge the record request (S45) that whether has from the user.Under having (S45 ' being ') from the situation of user's record request, take a decision as to whether in the format of backstage (S46), under the situation in format (S46 ' being '), interrupt backstage format (S47), carry out requested data recording (S48).The processing of step S41～S48 is carried out as backstage formatting step, backstage format parts, backstage format function.

In the backstage format (S46 ' denying '), then the processing of step S47 is skipped.On the other hand, under not from the situation of user's record request (S45 ' deny '), whether judgement has the format interrupt request (S49) from the user.If do not format interrupt request (S49 ' denying '), then judge whether it is in the format of backstage (S50).Here, under the situation in the format of backstage (S50 ' being '), wait for record request (S45) once more from the user.On the other hand, in the backstage format (S50 ' deny '), then transfer to backstage format beginning processing.

Here, at first from the formative start address in backstage, retrieve the cut zone N (S51) that comprises this address.Then, whether there is not posting field (S52) the cut zone 1 to N-1 of judgement in layer 1.Here, (M is layer 1 a cut zone, exists in 0≤M＜N-1) under the situation of posting field not (S52 ' being '), and the backstage start address is changed to the not recording address (S53) of cut zone M, beginning backstage format (S54) at cut zone M.

On the other hand, do not exist in the cut zone 1 to N-1 in layer 1 under the situation of posting field not (S52 not), skips steps S53 also begins backstage format (S54) from the not posting field of cut zone N (layer 0).

In addition, under having (S49 ' being '), transfer to the format Interrupt Process from the situation of user's format interrupt request.Here, at first judge whether be in the format of backstage (S55),, then interrupt backstage format (S56) if in the format (S55 ' being ').If not the format in (S55 ' denying '), then step S56 is skipped.The processing of step S55, S56 is performed as operation of recording interrupt step, operation of recording interruption member, operation of recording interrupt function.

Then, obtain finally recording address (S57), retrieve in the cut zone before this address, have a not cut zone of posting field (S58).The processing of step S58 is as posting field has or not determining step, posting field has or not decision means, posting field has or not arbitration functions to carry out.Its result, whether have corresponding cut zone (S59), if corresponding cut zone (S59 ' being ') is arranged, then write down not posting field (S60) in this cut zone with dummy data if judging.The processing of step S60 as correspondence not posting field data filling step, correspondence not posting field data filling component, correspondence not the posting field data fill function and carry out.After the record in this zone is finished, retrieve other region memory once more in the cut zone of posting field (S58) not.Like this, repeating step S58 is to step S60, with the whole records of cut zone before the final recording address.Its result is not comprising under the situation of the cut zone of posting field not (S59 ' denying '), from the final interim zone line (S61) of recording address opening entry, and then, the export area record is derived (S62), finish format and handle (S63).

In addition, in the present embodiment, substitute this processing as the dummy data record in the format of backstage, but in not carrying out the formative pen recorder in backstage, also can carry out the predetermined data record on the backstage.

That is, in the DVD+RW as rewritable DVD dish, adopt the backstage format, i.e. the format of carrying out carrying out before writing down from user's data on the backstage is handled.In the backstage format,, only (initial treatment) part of ingress area and come user notification format to finish,, carried out record with dummy data in remaining areas less than time from user's access by record for formatted requests from the user.Thereby as present embodiment, predetermined data record can be in that the time from user's medium accesses carry out on the backstage yet.Like this, by carrying out the predetermined data record on the backstage in time not from user's medium accesses, can shorten that medium is discharged or section finishes the required time, and, owing in from user's record, do not carry out the predetermined data record, therefore can prevent the reduction of record performance.In addition, owing in record, have under the situation from user's medium accesses request for the specified data of so not posting field, interrupt the operation of recording of this predetermined data, so can not bring obstacle, can carry out for the operation of recording of the predetermined data of posting field not to original access action.

In addition, for example, in the format of the backstage of DVD+RW, even format state midway also can take out medium.Among the DVD+RW, when taking out, medium carries out the formative Interrupt Process in backstage temporarily, but in this Interrupt Process, under the situation that will obtain with the exchange of existing read-only DVD driver, the not posting field between posting field of record becomes by after the continuous recording state with the dummy data record discontinuously on medium, from the interim derivation of final address record of posting field.Here, the information recording carrier with a plurality of recording layers is being carried out also considering to take out medium midway in this format in the formative information record carrier in backstage.At this moment, in order to guarantee to exchange, except the situation with DVD+RW is the format Interrupt Process of example narration, also need other the not posting field of recording layer is carried out the record of predetermined data with the reproduction of a read driver.Thereby,,, also can keep exchanging taking-up dish simultaneously by the reproduction of a read driver in this format even the CD 2 with a plurality of recording layers is being carried out under the formative situation in backstage according to the present invention midway.

In addition, usually, in the format of backstage, carry out the record of dummy data in the medium week continuously.Thereby, CD 2 with a plurality of recording layers is being carried out under the formative situation in backstage, suppose from being assigned with the first recording layer opening entry dummy data of minimum logical address, carry out the dummy data record of next record layer in the moment that the format of this recording layer has been finished.But, in the such record order in the format of backstage, consider in format to keep taking out medium simultaneously by the exchange of a read driver midway, then produce the time consuming rough sledding of the formative Interrupt Process in backstage.This is to need to carry out the predetermined data record owing to reckoning without in the format Interrupt Process.For example, data area for described first recording layer, format under the situation of interruption under the state that dummy data record that format causes has been finished at Zone Full roughly, in order to keep exchange, also have to write down roughly Zone Full with described specified data for other the data area of recording layer by a read driver.This respect, the data area of a plurality of recording layers is divided into a plurality of zones respectively, between a plurality of recording layers, alternately carry out record for these cut zone, thereby carry out handling for the format of described information recording carrier on the backstage, if will be made as the moment of in handling, receiving for the predetermined timing that posting field not writes down from user's backstage format interrupt request for the backstage format of CD 2, then in the dummy data record in the format of backstage, with the data area of a plurality of recording layers by each cut zone record that hockets, thereby under the situation that the format interrupt request is arranged, can reduce the zone of recording prescribed data, and can finish the format Interrupt Process with the short time.

Figure 11 A～11D be illustrated in such method carried out the formative situation in backstage and the situation of having carried out continuously from layer 0 under, need the difference of the scope of specified data record in the format Interrupt Process.

Figure 11 A carries out the formative situation in backstage continuously from layer 0 beginning.Here, suppose to receive format interrupt request from the user in the moment of the data area of roughly having write down layer 0 comprehensively.At this moment, shown in Figure 11 B, for to layer 0 in the layer 1 of the same radial location of posting field in the data area carry out record, must roughly carry out record to the data area of layer 1 comprehensively, the format Interrupt Process needs long-time.

On the other hand, Figure 11 C backstage format example of representing to carry out in the present embodiment.Here, the data zone is carried out 7 cut apart (dashed region among the figure), in each cut zone data area of recording layer 0 and layer 1 alternately.Thereby the progress situation of the record in the layer 0 is slower than the situation of Figure 11 A.Here, suppose to receive format interrupt request from the user in the moment shown in Figure 11 C.In this case, shown in Figure 11 D, format the zone that to write down in the Interrupt Process (with the not posting field in the layer 1 of the same radial location of posting field in the layer 0) as can be known and compare very little with the situation of Figure 11 B.Thereby, in the format of backstage, coil under the situation of discharge, according to present embodiment, can finish to format Interrupt Process the short time.

In addition, described embodiment all is to be illustrated as the application examples to the OTP mode, but can use too for the PTP mode.
