Fig. 2 is the example of hybrid recording AV data and PC data in same dish.As shown in the drawing, posting field is divided into three zones (ingress area (Lead-in Zone), data area (Data Zone) and export area (Lead-out Zone)) from interior all side direction outer circumferential sides.The data area is divided into the zone of storage file management information, the AV data area of storing image data, the PC data area of the data beyond the storage AV data.The AV data area comprises the zone of the storage control information relevant with view data and the zone of storing image data (Video Object).
Here, about the dish layout (disc layout) of the posting field in the existing defect management mode, use Fig. 3 explanation main portions relevant with defect management.In this conventional example, as one for example shown in Figure 3, posting field is divided into ingress area, data area and export area from interior all side direction outer circumferential sides.The defect management information zone that has the described defect management information of record etc. in the ingress area.The data zone is carried out the record and the reproduction of data.The specific address that is called physical address is allocated in advance in whole sectors of data area.This data area is split into replaces zone 1 (below be called ' SA1 '), user data area (below be called ' UDA ') and replaces zone 2 (below be called ' SA2 ').UDA is the zone of preparing for storaging user data.Each sector that comprises among this UDA is assigned with logical address, and the user uses this logic address access CD, carries out the record and the reproduction of data.
Then, the substitute mode of the defect area in the simple declaration defect management.The replacement of the defect area in the defect management generally uses slip (slip) to replace and linear two kinds of replacing.
In slide replacing, when detecting defect area, replace this defect area and the zone of using the next one to continue.Therefore, every generation is slided when replacing, and the physical address of the position in logical address that data are subsidiary and expression zone slides one.
In linear the replacement, when detecting defect area, use physically the replacement zone of having guaranteed in advance away from the position of defect area.In addition, in linearity is replaced, exist away from defect area physically owing to replacing the destination, therefore compare with the replacement of sliding, access sometimes needs the time.
For example, in DVD-RAM, replace for being used to slide by initialization process (format is handled) the detected defective (initial imperfection or a defective) of dish, detected defective (secondary defect) is used linear the replacement in the record for the user data after the initialization process.That is, in DVD-RAM, using simultaneously slides replaces and linear the replacement.And the defect information of initial imperfection is registered in the initial imperfection tabulation (Primary Defect List, ' PDL '), and secondary defect is registered in the secondary defect tabulation (Secondary Defect List, ' PDL ').
In DVD+RW, only use linear the replacement, only have a kind of defect list.
Then, be described cutting apart of data area in this first embodiment.The defect management mode of the dividing method of data area and each subregion can be specified by last bed device 90 by the user.Here, as an example, as shown in Figure 4, the data area is divided into two subregions (being made as UDA1, UDA2), being appointed as UDA1 is the zone of not carrying out defect management, and UDA2 is the zone of carrying out defect management.Then, in UDA2, use linear the replacement, carry out defect management for defective and secondary defect.In addition, UDA2 just is configured in after the UDA1.In addition, the replacement zone (SA2) of detected defect area just is configured in after the UDA2 in UDA2.The size of SA2 is by the size decision of UDA2.
The final address that logical address (LBA) is set to from the start address of data area to UDA2 increases continuously.That is, in the front and back on the border of UDA1 and UDA2, logical address is continuous.
In addition, piece as the storage information relevant with the each several part zone, redefine defect management information (Defect Management Information, below be called ' DMI ') piece, zone as this DMI piece of record, defect management information zone (Defect ManagementInformation Area below is called ' DMA ') is set in ingress area.
In this first embodiment, the information relevant with UDA1 and UDA2 is stored in the DMI piece.Promptly, here, as shown in Figure 5, the DMI piece is from the starting successively by the distinguishing mark (Signature) of 3 bytes, the version number of 1 byte (Version number), the DMI of 4 bytes is New count (DMIupdate count) more, the UDA1 start address pointer of 4 bytes (UDA1 start Address pointer), the UDA1 end address pointer of 4 bytes (UDA1 end Address pointer), the UDA2 start address pointer of 4 bytes (UDA2 start Address pointer), the UDA2 end address pointer of 4 bytes (UDA2 end Address pointer), the SA2 size of 4 bytes (SA2 size), the replacement list-item of 4 bytes number (Number of Replacement List (RPL) entries), the RPL project 0 of 8 bytes (RPL entry 0), the RPL project 1 of 8 bytes (RPL entry 1), the RPL project N of 8 bytes (RPL entry N) constitutes.In addition, the BP among Fig. 5 is a byte pointer, and expression is from the byte number of the beginning of DMI piece.
The ASC sign indicating number (444D49h) of storage DMI is the ID of DMI piece as this piece of expression in the described distinguishing mark.The version number of this DMI piece of storage in the described version number.Described DMI more stores the number of times that the DMI piece is updated in the New count.The start address of storage UDA1 in the described UDA1 start address pointer, the end address of storage UDA1 in the pointer of described UDA1 end address.The start address of storage UDA1 in the described UDA2 start address pointer, the end address of storage UDA2 in the pointer of described UDA2 end address.The size of storage SA2 in the described SA2 size.The number of tabulation is replaced in storage in the described exchange list-item number (below be made as ' N_RPL ').Here, as an example, suppose to exist N to replace tabulation.Described RPL project 0, RPL project 1 ..., RPL project N (below be generically and collectively referred to as ' RPL project ') replaces tabulation, the address of the replacement that replace the address in storage defect zone and this defect area carried out.In the present embodiment, UDA1 is the zone of not carrying out defect management, does not therefore have the defect management information corresponding with UDA1.Thereby SA2 size, N_RPL and RPL project are the defect management informations corresponding with UDA2.
Then, use the processing when last bed device 90 receives the order (below be called ' formatting command ') of formatted requests of optical disc apparatus 20 that Fig. 6 explanation constitutes as previously mentioned.The process flow diagram of Fig. 6 is corresponding to a series of Processing Algorithm of being carried out by CPU40.In addition, suppose that CD 15 is blank discs.
When last bed device 90 received formatting command, the front end address of the program corresponding with the process flow diagram of Fig. 6 (below be called ' formatted program ') was set in the programmable counter of CPU40 the formatted program starting.
In initial step 301, obtain the dividing method of the data area that is set by the user and the information relevant with the defect management mode in each several part zone via last bed device 90.Here, as an example, as previously mentioned, the tentation data zone is split into two subregions (UDA1, UDA2), and UDA1 is the zone of not carrying out defect management, and UDA2 is the zone of carrying out defect management, uses linear the replacement among the UDA2.
In the step of following 303, based on the information partition data zone of having obtained.Then, decide the size of SA2 according to the size of UDA2.
In the step of following 305, each subregion is generated defect management information based on the information that has obtained.Here, generate aforesaid DMI piece.
In the step of following 307, the defect management information (DMI piece) that generates is recorded among the DMA of CD 15.
In the step of following 309, the initialization process of beginning CD 15 (format is handled).
In the step of following 311, judge whether the format processing is finished.If format is handled do not finish, then here be judged as negatively, and standby is finished dealing with up to format.In addition, in format is handled, carry out the detection of a defective for UDA2 and handle.Then, when defective was detected, decision was replaced the address and is registered in the replacement in the table, upgrades and replaces tabulation.After format was finished dealing with, being judged as here was sure, after the end process of having carried out regulation, and the processing when finishing to receive formatting command.
In addition, format handle also can be the necessary minimal information of record, dummy data be recorded in not access from the user time the so-called backstage format carried out handle.
Then, use the processing of Fig. 7 explanation when last bed device 90 receives the order (below be called ' record request order ') of record request.The process flow diagram of Fig. 7 is corresponding to a series of Processing Algorithm of being carried out by CPU40.In addition, suppose that CD 15 finished format and handled.
When last bed device 90 received the record request order, the front end address of the program corresponding with the process flow diagram of Fig. 7 (below be called ' first recording processing program ') was set in the programmable counter of CPU40 the starting of first recording processing program.
In initial step 401, obtain the subregion that comprises request address (below be also referred to as ' object part zone ').Here, UDA1 or UDA2 become the object part zone.
In the step of following 403, request address is transformed to recording address with reference to defect management information.
Here, when being UDA1, request address is added that the physical address behind the UDA1 start address pointer becomes recording address in the object part zone.
On the other hand, when the object part zone is UDA2, request address is added UDA1 start address pointer and is transformed to physical address, if this physical address is unregistered in replacing tabulation (RPL project), then physical address still is a recording address, replace in the tabulation if be registered in, then alternately destination-address becomes recording address.
In the step of following 405, indication is to the data recording in the represented zone of recording address.Thus, data (user data) are recorded in the CD 15 via scrambler 25, laser control circuit 24 and optical take-up apparatus 23.
In the step of following 407, the whether normal termination of the record of judgment data.If the not normal termination of the record of data, then here be judged as negatively, transfer to step 409.
In this step 409, judge whether the object part zone is the zone of carrying out defect management.If the object part zone is UDA2, then be the zone of carrying out defect management, therefore being judged as certainly here transferred to step 411.
In this step 411, decision is replaced the address and is registered in and replaces in the tabulation, upgrades and replaces tabulation.In addition, the logical address that is assigned to defect area is assigned to the replacement address of having replaced this defect area place.
In the step of following 413, carry out the replacement of data.
In the step of following 415, judge whether the object part zone is the zone of carrying out defect management.If the object part zone is UDA2, then be the zone of carrying out defect management, therefore being judged as certainly here transferred to step 419.
In the step of following 419, carry out verification (verify) and handle.For example, reproduce the zone of having write down data, ask error rate.
In the step of following 421,, judge whether to exist defective based on the result of checking treatment.For example, if more than the value of error rate for regulation, then being judged as certainly here transferred to step 423.
In this step 423, decision is replaced destination-address and is registered in and replaces in the tabulation, upgrades and replaces tabulation.
In the step of following 425, carry out the replacement of data.Then, finish first recording processing program.
In addition, in described step 415,, then be the zone of not carrying out defect management, so being judged as in the step 415 is negative, finishes first recording processing program if the object part zone is UDA1.In addition, in described step 421, if do not detect defective, then in the step 421 be judged as negative, finish first recording processing program,
And then, in described step 409,, then be the zone of not carrying out defect management if the object part zone is UDA1, being judged as in the step 409 is negative, transfers to step 427.In this step 427,90 couples of users carry out error reporting by last bed device.Then, finish first recording processing program.
In addition, in described step 407, if the record normal termination of data, then being judged as certainly in the step 407 transferred to step 415.
Thereby, under data are recorded in situation among the UDA1, do not carry out the replacement of defects detection and defect area, therefore can avoid damaging the real-time of data recording.In addition, under data are recorded in situation among the UDA2, carry out the replacement of defects detection and defect area, therefore can guarantee reliability of recording data.
From above explanation as can be known, in the optical disc apparatus 20 of this first embodiment, realize set parts and defect management parts by CPU40 and the program carried out by this CPU40.That is,, realize the defect management parts by step 407～425 of Fig. 7 by step 303 and the 305 realization set parts of Fig. 6.In addition, constitute recording-member by CPU40 and program, optical take-up apparatus 23, laser control circuit 24 and the scrambler 25 carried out by this CPU40.
In addition, can constitute at least a portion of each parts of realizing by processing, perhaps also can all constitute by hardware by hardware according to the program of CPU40.
In addition, in this first embodiment, be installed in formatted program described in the program in the flash memory 39 and described first recording processing program constitutes program of the present invention.Promptly, constitute the step of setting by program corresponding to the processing of the step 303 of Fig. 6 and 305, constitute the step that writes down by the program corresponding, constitute the step of carrying out defect management by the program corresponding with step 407～425 of Fig. 7 with the step 307 of Fig. 6.
Then, implement the step of setting in the defect management information setting method of the present invention, implement the step that writes down by the processing of the step 307 of Fig. 6 by the processing of the step 303 of Fig. 6 and 305.In addition, implement the step of carrying out defect management in the defect management method of the present invention by the processing of step 407～425 of Fig. 7.
As described above, according to the optical disc apparatus of this first embodiment, when receiving the formatting command for the CD 15 of blank, defect management information is set to each subregion in the partition data zone.Therefore, by the data area being divided into zone (UDA1) of not carrying out defect management and the zone (UDA2) of carrying out defect management, the information that writes down in can UDA1 can be guaranteed the continuity of data, and the information that writes down among the UDA2 can be guaranteed the reliability of data.For example, zone by UDA1 being made as record AV data (below be called ' AV data area '), UDA2 is made as the PC data area, in same dish, during the data of hybrid recording AV data and such purposes of PC data or different in kind, can carries out best record each data.Thereby, can be to same information recording carrier recording use or character different several data mutually suitably.
In addition, because defect management information is recorded in the CD 15, so when CD 15 is set up once more, can correctly discern the defect management mode in the each several part zone, the information that writes down among the UDA1 is guaranteed the continuity of data, and the information that writes down among the UDA2 is guaranteed the reliability of data.In addition, even use under the situation of different optical disc apparatus, also can guarantee interchangeability.
In addition, the defect management mode of the dividing method of data area and each subregion can at random be set by the user, therefore can realize the defect management corresponding to user's purposes.
In addition, in the above-described first embodiment, because UDA1 end address pointer and UDA2 end address pointer are continuous,, also can will add that to request address the address of UDA1 end address pointer is as physical address no matter therefore the object part zone is UDA1 or UDA2.Thereby, can simply logical address be transformed to physical address.In addition, if UDA1 end address pointer and UDA2 start address pointer are discontinuous, be under the situation of UDA2 then in the object part zone, need this discontinuous size of consideration to ask physical address.
In addition, because continuous at the front and back physical address on the border of UDA1 and UDA2, therefore in the interregional continuity of guaranteeing logical address of each several part, the user can come the specified portions zone according to logical address.
In addition, owing to there be not the replacement zone corresponding, therefore can effectively utilize the data area with the UDA1 that does not carry out defect management.
In addition and since with CD 15 initialization the time setting data zone cut apart with the each several part zone in the defect management mode, therefore the defect management in the data recording thereafter becomes easy.
In addition, in the above-described first embodiment, illustrated that the replacement zone of UDA2 just is configured in UDA2 situation afterwards, but be not limited to this.
" variation "
Use Fig. 8～Figure 10 that the variation of above-mentioned first embodiment is described.This variation is for example shown in Figure 8 as one, and the described SA2 in above-mentioned first embodiment is divided into two (being made as SA2-1, SA2-2), at the place ahead of UDA2 configuration SA2-1, at the rear of UDA2 configuration SA2-2.That is, cut apart the front and back that are configured in UDA2 as the SA2 in the replacement zone of UDA2, this point is different with first embodiment.
Have SA2-1 between UDA1 and the UDA2, but as shown in Figure 8, physical address (LBA) is set to from the start address of data area to be increased continuously in UDA1 and UDA2.Thereby in SA2-1, logical address is skipped.
In this case, as shown in Figure 9, the DMI piece is from the starting successively by the distinguishing mark (Signature) of 3 bytes, the version number of 1 byte (Version number), the DMI of 4 bytes is New count (DMIupdate count) more, the RPL piece of 2 bytes number (Number of RPL blocks), the reservation of 6 bytes (Reserved), the RPL piece 1 of 32 bytes (RPL block 1), the RPL piece 2 of 32 bytes (RPL block2), the RPL2 project 0 of 8 bytes (RPL2 entry 0), the RPL2 project 1 of 8 bytes (RPL2 entry1), the RPL2 project N of 8 bytes (RPL2 entry N) constitutes.
The ASC sign indicating number (444D49h) of storage DMI is the ID of DMI piece as this piece of expression in the described distinguishing mark.The version number of this DMI piece of storage in the described version number.Described DMI more stores the number of times that the DMI piece is updated in the New count.The number of storage RPL piece in the described RPL piece number.This RPL piece is the piece that redefines here, stores address information and the relevant information of defect management mode with the subregion.Therefore, only there is the number of subregion in the RPL piece.Here, owing to there are two subregions (UDA1, UDA2), therefore there are two RPL pieces.Thereby, storage ' 02h ' in this RPL piece number.In addition, the detailed form of back narration RPL piece.Described reservation is to be the zone of preengaging in the future, storage ' 00h '.The storage RPL piece corresponding in the described RPL piece 1 with UDA1.The storage RPL piece corresponding in the described RPL piece 2 with UDA2.Described RPL2 project 0, RPL2 project 1 ..., RPL2 project N (below be generically and collectively referred to as ' RPL2 project ') is respectively the replacement tabulation of UDA2, the address of the replacement that replace the address in storage defect zone and this defect area carried out.In addition, because UDA1 is the zone of not carrying out defect management, therefore there is not RPL1 project as the replacement tabulation of UDA1.In addition, the memory location of replacement tabulation changes according to the size of subregion number and graded area.
Here, described RPL piece is described.
This RPL piece is the piece of 32 bytes, as shown in figure 10, and with the common subregional information of form storage part.The RPL piece is from the starting successively by the distinguishing mark (Signature) of 3 bytes, the RPL piece of 1 byte number (RPL Block number), the UDA start address pointer of 4 bytes (UDA start Addresspointer), the UDA end address pointer of 4 bytes (UDA end Address pointer), the SA-1 size of 4 bytes (SA-1 size), the SA-2 size of 4 bytes (SA-2 size), the RPL item number of 4 bytes (Number of RPL entries), the position of the RPL project 0 of 2 bytes (Location of RPLentry 0), the reservation of 6 bytes (Reserved) constitutes.
The ASC sign indicating number (52504Ch) of storage DMI is the ID of RPL piece as this piece of expression in the described distinguishing mark.In the described RPL piece number this RPL piece of storage number.The RPL piece is number identical with UDA number, represents which subregion is corresponding to this RPL piece.The start address of the subregion of storage correspondence in the described UDA start address pointer.The end address of the subregion of storage correspondence in the pointer of described UDA end address.The size of storage SA-1 in the described SA-1 size.The size of storage SA-2 in the described SA-2 size.In addition, the size of the size of SA-1 and SA-2 is according to the size of the subregion of correspondence and determined.The number (N_RPL) of tabulation is replaced in storage in the described RPL item number.In the position of described RPL project 0 (below be called ' RPL positional information ') with the positional information of the initial RPL project the RPL project of tabulating as the replacement of corresponding subregion from off-set value (byte location) storage of the front end of DMI piece.Therefore, the starting position of the replacement in each several part zone tabulation can be determined according to the RPL positional information in the RPL piece.Described reservation is to be the zone of preengaging in the future, storage ' 00h '.
Here, because UDA1 is the zone of not carrying out defect management, therefore there are not SA-1 (being SA1-1 here) and SA-2 (being SA1-2 here).Thereby the RPL piece corresponding with UDA1 be storage ' 0 ' respectively in SA-1 size, SA-2 size, N_RPL and RPL positional information.
On the other hand, UDA2 is the zone of carrying out defect management, has SA-1 (being SA2-1 here), SA-2 (being SA2-2 here).Thereby, the value of the RPL piece corresponding store predetermined in SA-1 size, SA-2 size, N_RPL and RPL positional information with UDA2.Here, suppose to exist N to replace tabulation.That is N_RPL=N.In addition, owing to the replacement of UDA2 is tabulated from the 80th byte of DMI piece, so storage ' 80 ' in the RPL positional information.In addition, for example above-mentioned first embodiment does not exist under the situation of replacing the zone in the place ahead of UDA2 like this, and storage ' 0 ' gets final product in the SA-1 size.
In this variation, when last bed device 90 receives formatting command, described formatted program starting.But, in described step 303, decide the size of SA2-1 and SA2-2 according to the size of UDA2.
In addition, in this variation, from bed device 90 when receiving the record request order, the described first record request programming start.But in described step 403, when being UDA2 in the object part zone, the consideration logical address is skipped at SA2-1 asks physical address.
In addition, in described step 411 and 423, near the replacement zone of defect area, decision is replaced destination-address and also is registered in the replacement tabulation, and tabulation is replaced in renewal among selection SA2-1 and the SA2-2.
As described above, according to this variation, because as the replacement zone that is used to replace the defective in the UDA2, dispose SA2-1 in the place ahead of UDA2, dispose SA2-2 in the wings, therefore detected defective can be used replacement zone near among SA2-1 and the SA2-2 in UDA2.Thus, can shorten the tracking distance, and can further shorten and replace the access time of handling.
In addition, owing to be provided with the zone (RPL piece) of the defect management information of storage UDA1, therefore according to user's purposes, UDA1 also can carry out defect management, becomes than the general form of above-mentioned first embodiment.
In addition, between UDA1 and UDA2, exist and replace region S A2-1, but in UDA1 and UDA2, because logical address is continuous, therefore in the interregional continuity of guaranteeing logical address of each several part, the user can come the specified portions zone by logical address.
In addition, in above-mentioned variation, in DMI piece stored replace tabulation, but also can replace list storage in the different zone of territory DMI piece.
" second embodiment "
Then, use Figure 11～Figure 13 that second embodiment of the present invention is described.This second embodiment all carries out defect management as shown in figure 11 in any one of UDA1 and UDA2, this point is different with above-mentioned first embodiment.And region S A1 is replaced in configuration at the rear of UDA1, and decentralized configuration has a plurality of replacement region S A2 (to be made as SA2-1～SA2-4) here, in UDA2.Thereby the part of program stored is different with first embodiment in the flash memory 39, and the structure of optical disc apparatus etc. are same with described first embodiment.Therefore, following, be that the center describes with difference with first embodiment, simultaneously use prosign for the component part identical or equal with described first embodiment, simplify or omit its explanation.
Logical address (LBA) is set in UDA1 and UDA2 as shown in figure 11, increases continuously from the start address of data area.Thereby in SA1, SA2-1, SA2-2, SA2-3 and SA2-4, logical address is skipped.
In this case, the DMI piece is for example shown in Figure 12 as one, from the starting successively by the distinguishing mark (Signature) of 3 bytes, the version number of 1 byte (Verrsion number), the DMI of 4 bytes is New count (DMI update count) more, the RPL piece of 2 bytes number (Number of RPL blocks), the reservation of 6 bytes (Reserved), the RPL piece 1 of 64 bytes (RPL block 1), the RPL piece 2 of 64 bytes (RPL block 2), the RPL1 project 0 of 8 bytes (RPL1 entry 0), the RPL1 project 1 of 8 bytes (RPL2 entry 1), the RPL1 project N1 of 8 bytes (RPL2 entry N1), the RPL2 project 0 of 8 bytes (RPL2 entry 0), the RPL2 project 1 of 8 bytes (RPL2 entry1), the RPL2 project N2 of 8 bytes (RPL2 entry N2) constitutes.That is then RPL piece storage replacement tabulation in the DMI piece.
The ASC sign indicating number (444D49h) of storage DMI is the ID of DMI piece as this piece of expression in the described distinguishing mark.The version number of this DMI piece of storage in the described version number.Described DMI more stores the number of times that the DMI piece is updated in the New count.The number of storage RPL piece in the described RPL piece number, this RPL piece has been stored address information and the relevant information of defect management mode with the subregion.RPL piece in this second embodiment have with above-mentioned variation in the different data structure of piece that defines.Only there is the number of subregion in this RPL piece.Here, owing to there are two subregions (UDA1, UDA2), therefore there are two RPL pieces.Thereby, storage ' 02h ' in this RPL piece number.In addition, the detailed form of back narration RPL piece.Described reservation is to be the zone of preengaging in the future, storage ' 00h '.The storage RPL piece corresponding in the described RPL piece 2 with UDA2.Described RPL1 project 0, RPL1 project 1 ..., RPL1 project N1 (below be generically and collectively referred to as ' RPL1 project ') is respectively the replacement tabulation of UDA1, the address of the replacement that replace the address in storage defect zone and this defect area carried out.Described RPL2 project 0, RPL2 project 1 ..., RPL2 project N2 (below be generically and collectively referred to as ' RPL2 project ') is respectively the replacement tabulation of UDA2, the address of the replacement that replace the address in storage defect zone and this defect area carried out.In addition, the memory location of replacement tabulation changes according to the size of subregion number and graded area.
Here, described RPL piece is described.
This RPL piece is the piece of 64 bytes, as shown in figure 13, is made of with the part (BP=32～63) to the different format record of each RPL identifier with described later the part (BP=0～31) with common format record.The RPL piece is from the starting successively by the distinguishing mark (Signature) of 3 bytes, the RPL piece of 1 byte number (RPL Block number), the RPL identifier of 1 byte (RPL Block type), the reservation of 3 bytes (Reserved), the UDA start address pointer of 4 bytes (UDA start Addresspointer), the UDA end address pointer of 4 bytes (UDA end Address pointer), the RPL item number of 4 bytes (Number of Replacement List (RPL) entries), the position of the RPL project 0 of 2 bytes (Location of RPL entry 0), the reservation of 10 bytes (Reserved), the RPL piece particular data of 32 bytes (RPL Block specific data) constitutes.
The ASC sign indicating number (52504Ch) of storage DMI is the ID of RPL piece as this piece of expression in the described distinguishing mark.In the described RPL piece number this RPL piece of storage number.The RPL piece is number identical with UDA number, represents which subregion is corresponding to this RPL piece.The kind of this RPL piece of storage in the described RPL identifier.The start address of the subregion of storage correspondence in the described UDA start address pointer, the end address of the subregion of storage correspondence in the pointer of described UDA end address.The number (N_RPL) of tabulation is replaced in storage in the described RPL item number.In the position of described RPL project 0 (below be called ' RPL positional information ') with the positional information of the initial RPL project the RPL project of tabulating as the replacement of corresponding subregion from off-set value (byte location) storage of the front end of DMI piece.Thereby the starting position of the replacement tabulation in each several part zone can be determined according to the RPL positional information in the RPL piece.Described each reservation is the zone for preengaging in the future, storage ' 00h ' respectively.Described RPL piece particular data is with the detailed content of the applied defect management mode in subregion of the form of each RPL identifier decision being stored this RPL piece and representing.As an example, the having or not of the having or not of store defect management information (comprising having or not of each defective (defective, secondary defect)), substitute mode (linearly replace, slide replace etc.), the configuration of replacing the zone, verification (comprise with the relevant information in verification zone), replacement condition (comprising the determining defects benchmark), replace the information such as form of tabulating in this RPL piece particular data.
Therefore, here, be made as in UDA1 and use linear the replacement, only carry out defect management for a defective.In addition, be made as in UDA2 and use linear the replacement, carry out defect management for defective and secondary defect.These information are stored in the RPL piece when making defect management information.
When last bed device 90 receives formatting command, the formatted program starting identical with above-mentioned first embodiment.But, in described step 303, the size that decides SA1 according to size and the defect management mode of UDA1, the size that decides SA2-1～SA2-4 according to size and the defect management mode of UDA2.Here, therefore defect managed only in UDA1 is compared with the situation that secondary defect also manages, and the size of SA1 is littler.
In addition, in format is handled, carry out the detection management of a defective based on the RPL piece particular data of storage in the RPL piece 1 for UDA1.Then, when detecting defective, decision is replaced the destination and is registered in and replaces in the tabulation, upgrades and replaces tabulation.In addition, carry out the detection management of a defective based on the RPL piece particular data of storage in the RPL piece 2 for UDA2.Then, when detecting defective, decision is replaced the destination and is registered in and replaces in the tabulation, upgrades and replaces tabulation.
Then, use the processing of Figure 14 explanation when last bed device 90 receives the record request order.The process flow diagram of Figure 14 is corresponding to a series of Processing Algorithm of being carried out by CPU40.In addition, suppose that CD 15 finished format and handled.
When last bed device 90 received the record request order, the front end address of the program corresponding with the process flow diagram of Figure 14 (below be called ' second recording processing program ') was set in the programmable counter of CPU40 the starting of second recording processing program.
In step 501～503, carry out the processing identical with the processing of described step 401～403.But in described step 503, when being UDA2 in the object part zone, the consideration logical address is skipped in replacing the zone asks physical address.
In the step of following 504,, judge whether the RPL identifier is known with reference to defect management information.If the RPL identifier is known, then being judged as certainly here transferred to step 505.
In the step of following 505, indication is to the record of the data in the represented zone of recording address.
In the step of following 507, the whether normal termination of the record of judgment data.If the not normal termination of the record of data, then here be judged as negatively, transfer to step 509.
In this step 509,, judge whether the object part zone is the zone of carrying out for the replacement processing of secondary defect with reference to defect management information.If the object part zone is UDA2, then be the zone of carrying out for the defect management of second zone, therefore being judged as certainly here transferred to step 511.
In described step 511, because object part zone be UDA2, therefore select among SA2-1～SA2-4 replacement zone near defect area, decision is replaced destination-address and also is registered in and replaces in the tabulation, and upgrades replacement and tabulate.In addition, the logical address that defect area is distributed is assigned to the replacement address with this defect area replacement place.
In the step of following 513, carry out the replacement of data.
In then step 515,, judge that whether the object part zone is the zone of carrying out the checking treatment after the data recording with reference to defect management information.If the object part zone is UDA2, then be the zone of carrying out checking treatment, therefore being judged as certainly here transferred to step 517.
In this step 517, the replacement condition from defect management information in the extraction checking treatment etc.Here, for example based on the determinating reference of defective, decision uses error rate also to be to use the PI byte of ECC piece and one of them of PO byte.
In the step of following 519, carry out checking treatment.
In the step of following 521, the determinating reference that comprises in the RPL piece particular data based on storage in the RPL piece 2 judges whether defectiveness.For example, the judgement of defective is being used under the situation of error rate, if error rate more than setting, then being judged as certainly here transferred to step 523.
Therefore because object part zone be UDA2, select among SA2-1～SA2-4 the replacement zone near defect area in this step 523, decision is replaced destination-address and also is registered in and replaces in the tabulation, and upgrades replacement and tabulate.
In the step of following 525, carry out the replacement of data.Then, finish second recording processing program.
In addition, in described step 515,, then be the zone of not carrying out checking treatment, so being judged as in the step 515 is negative if the object part zone is UDA1, second recording processing program finishes.In addition, in described step 521, if defective is not detected, then be judged as negatively in the step 521, second recording processing program finishes.
And then, in described step 509,, then be not carry out the zone of handling, so being judged as in the step 509 is negative, transfers to step 527 for the replacement of secondary defect if the object part zone is UDA1.In addition, in this step 527,90 couples of users carry out error reporting by last bed device.Then, second recording processing program finishes.
In addition, in described step 507, if the record of data normally finishes, then being judged as certainly in the step 507 transferred to described step 515.
And then, in described step 504, if the unknown of RPL identifier, then here be judged as negatively, transfer to step 526.In this step 526, the record of forbidden data.Then, transfer to described step 527.
As seen from the above description, in the optical disc apparatus 20 of this second embodiment,, realize set parts and defect management parts by CPU40 and the program carried out by this CPU40.That is,, realize the defect management parts by step 507～525 of Figure 14 by step 303 and the 305 realization set parts of Fig. 6.In addition, constitute recording-member by CPU40 and program, optical take-up apparatus 23, laser control circuit 24 and the scrambler 25 carried out by this CPU.
In addition, can constitute by hardware according at least a portion of each parts of the processing realization of program, perhaps also can all constitute by hardware by CPU40.
In addition, in this second embodiment, constitute program of the present invention by formatted program described in the program of installing in the flash memory 39 and described second logging program.Promptly, constitute the step of setting by the program corresponding with the processing of the step 303 of Fig. 6 and 305, constitute the step that writes down by the program corresponding with the step 307 of Fig. 6, constitute the step of judging by the program corresponding with the step 504 of Figure 14, step by the program realization permissions records corresponding with the step 505 of Figure 14 constitutes the step of carrying out defect management by the program corresponding with step 507～525 of Figure 14.
Then, the step of setting in the defect management information setting method of the present invention is implemented in step 303 by Fig. 6 and 305 processing, is implemented the step that writes down by the processing of the step 307 of Fig. 6.In addition, implement the step of carrying out defect management in the defect management method of the present invention by the processing of step 507～525 of Figure 14.
In addition, implement the step of judging in the recording method of the present invention, implement the step of permissions records by the processing of step 505 by the processing of the step 504 of Figure 14.
As described above,,, therefore UDA1 and UDA2 are used different defect management mutually in UDA1 and UDA2, can be suitable for the defect management in each several part zone because the RPL piece is set respectively according to the optical disc apparatus of this second embodiment.That is,, therefore can carry out more complicated defect management owing to have each defect management information independently to a plurality of subregions.For example, by with UDA1 as the AV data area, UDA2 as the PC data area, in the time of will being recorded in the CD 15 as the data mixing of purposes AV data and the PC data or different in kind, can be carried out best record to each data.Thereby, can be suitably in same information recording carrier recording use or the character data of different a plurality of kinds mutually.
In addition, owing to determine to replace the size in zone according to the defect management mode, so can place the zone that produces waste.
In addition, because defect management information comprises the identifier of the data structure that is used to discern this defect management information, therefore can store information to each defect management mode the best.Thereby, can mix subregion of carrying out simple defect management and the subregion of carrying out complicated defect management.
In addition, because a plurality of subregions have independently determining defects benchmark respectively, therefore can be suitable for the defects detection in each several part zone.
In addition, because a plurality of replacement region S of decentralized configuration A2 (, is made as SA2-1～SA2-4) here, therefore in UDA2, can uses than the replacement zone of above-mentioned variation near defect area, and can further shorten and replace the access time of handling in UDA2.
In addition, between UDA1 and UDA2, exist and replace region S A1, but in UDA2, have a plurality of replacement region S A2, but continuous owing to logical address in UDA1 and UDA2, therefore in the interregional continuity of guaranteeing logical address of each several part, the user can come the specified portions zone by logical address.
That is,, therefore can be suitable for the configuration in the replacement zone of defect management mode because the each several part zone independently has the zone of replacement respectively.For example, under the data conditions of user or the different in kind as AV data and PC data of hybrid recording in the same dish, can avoid in the AV data area, making and replace the zone waste, and in the PC data area, replace the zone near configuration as far as possible.
In addition, because the defect management information of each subregion is recorded in the CD,, also can correctly discerns the defect management mode in each several part zone, and can guarantee interchangeability even therefore insert other optical disc apparatus.In addition, even under the situation that begins logical address midway of data area,, therefore can easily tackle owing to stored the start address of UDA1.
In addition, before data recording, judge whether RPL identifier (identifier) is known, under the RPL identifier was known situation, therefore permissions records can carry out suitable defect management based on defect management information.Thereby, as a result of, can be in same information recording carrier recording use or character data of different a plurality of kinds mutually suitably.
In addition, in the above-described 2nd embodiment, also can change the size of replacing tabulation for each RPL identifier.
In addition,, and when the dish initialization, replace defective one time by sliding in advance, can avoid using the defective that in UDA1, produces for example by UDA1 being made as the AV data area.In this case, regional as an alternative, as long as the size of a defective can replacing anticipation is arranged.And, do not carry out secondary and replace by in UDA1, being set at, the defects detection in the record of AV data can be do not carried out, and the real-time of data recording can be guaranteed.On the other hand, by being set at UDA2, and replacing by linearity and to carry out the replacement of secondary defect, can guarantee reliability of recording data as the PC data area.
