● replace the replacement goal displacement district of address process and Data Update processing as being used for defective, use the position of selecting in the main data area (perhaps user data area) on recording medium.The example of this position is the appendix measuring point in the continuous recording scope (perhaps track).Replace the goal displacement district replaces the target area in address process and the Data Update processing as defective replacement.
● produce definite result of record data whether in order to make data recording/reproducing device, be adopted as the appendix recording technique and the orbit information that the provides information of continuous recording scope (perhaps about) about the place, an address on recording medium.That is to say, suppose to adopt to be generally appendix recording technique (packet writing technology or incremental record technology) that CD and DVD provide on being created in an address, whether use the orbit information that makes the supervisor status that is used for managing the recording medium that adopts the appendix recording method by data recording/reproducing device among definite result of record data as recording method.Usually, about the information of track or only comprise start address, end address and the appendix measuring point of continuous recording scope about the information of continuous recording scope.In the situation of this appendix recording method, data have been recorded in the district between start address and the address before being right after the appendix measuring point.On the other hand, also there are not record data in the district between appendix measuring point and end address.Therefore, can set up the record of recording medium and not recording status to mapping about the information of track, make data recording/reproducing device can produce about data at the destination address place definite result of record data whether.
In addition, according to the present invention, can have such as the recording medium of the dish of write-once type and to be used to manage the replacement address directorial area and the predistribution of replacing address information and to replace the district.In this case, in order to realize that defective is replaced address process and Data Update is handled, adopt following technology.
● to be provided for the replacement address information that managing data updates is handled with the identical form of form that has existed, be used for the replacement address information of managing defect replacement address process, and in addition, with with do not comprise that predistribution replaces the identical mode of recording medium in district, be used for the replacement address information that managing data updates handles and be used for managing defect replacing the replacement address information co-exist of address process in replacing the address directorial area.
● replace the replacement goal displacement district of address process and Data Update processing as being used for defective, use the position of selecting in the middle of a plurality of positions in predistribution replacement district.When predistribution replacement Qu Zhongwei stays available district, promptly when replace in defective address process and Data Update handle in all predistribution when replacing the district and running out, be chosen in the goal displacement position as an alternative, position in the main data area (perhaps user data area) on the recording medium.The example of this position is the appendix measuring point in continuous recording scope (perhaps track).
● with do not comprise that predistribution replaces the identical mode of recording medium in district, whether data recording/reproducing device uses orbit information in the appendix recording method information of continuous recording scope (perhaps about) among definite result of record data on producing about an address on recording medium.
As mentioned above, according to the present invention, the recording medium such as write-once discs can have the replacement address directorial area that is used to manage the replacement address information, and can not comprise predistribution replacement district.Replace address process and Data Update processing even in this case, can carry out defective.That is to say, can carry out defective by following step and replace address process and Data Update processing and do not need predistribution to replace the district:
Selected district in the main data area the appendix measuring point of use in the main data area is the goal displacement district as an alternative;
Produce about the place, address of appointment in data write request etc. whether among definite result of record data use about the information of track the information of continuous recording scope (perhaps about); With
Being mixed for managing defect in public block of information, replacement address replaces the replacement address information of address process and is used for the replacement address information that managing data updates is handled.
As a result, can obtain following effect.
The first, in using etc., no longer need to estimate in advance to replace the suitable dimension in district.No longer need to distribute the fact of replacing the district to mean effective utilization of main data area or user data area.
Second, utilize recording operation by using common file system to carry out, consider operation in the management information of disc recording file and renewal this document, the search distance of pick-up can be shortened to enough little value, be used for compensation and replace address function pick-up is moved to replacement goal displacement district.As an alternative, the management information of file can be recorded in the district that follows these data.Thus, can improve record performance.This technology is effective especially to following situation, and wherein replacing the goal displacement address is locational appendix measuring point on the direction that is located at backward, that separate with the current location of pick-up.That is to say, replace one maximum in the middle of the address that the goal displacement address is a plurality of appendix measuring point.
And, even because the address in the write request has formerly detected the fact of defective, must be from replacement goal displacement address read-outing data corresponding to the address of appointment this past data write request, but because the shorter search distance of pick-up, so also improved the reproduction performance.This technology is effective especially to following situation, and wherein replacing the goal displacement address is the appendix measuring point that is arranged in the continuous recording scope identical with assigned address (perhaps identical track).
On this, if according to about comprising that representative data writes the information of the appendix measuring point in the continuous recording scope of continuous recording scope of replacement target source address of address of appointment in the processing being different from, select to replace the replacement goal displacement address of address process, can remove the replacement address management information that causes owing to the generation of being upgraded by the continuous unnecessary data of application start in some environment, exist for renewal unnecessarily increases the problem of replacing address management information.
In addition, do not comprise that replacing the Write-once disc of distinguishing can realize the Data Update function, keep and the common once writing recording medium and the record and the reproduction compatibility of RAM and ROM type recording medium with original the same simultaneously.Therefore, the file system that is generally RAM type dish and ROM type dish and provides also can be used to Write-once optical disc and not need to revise hardware and physical format.
And according to above-mentioned the present invention, the recording medium such as write-once discs can have replacement address directorial area and the predistribution replacement district that is used to manage the replacement address information.In this case, become when being not enough to be used for defective replacement address process and Data Update processing, also can carry out these processing even the size in the district that stays in the district is replaced in predistribution.
When in predistribution replacement district, not staying available district, just, all predistribution is replaced and is distinguished when running out when replace address process and Data Update processing in defective in, the position in the main data area on the recording medium (or user data area) is elected as replaced the goal displacement position.Therefore, application waits the suitable dimension that needn't estimate to replace the district again.
In addition, also no longer need to distribute too large-sized replacement district according to the supposition that many excessive datas are upgraded.Therefore, can utilize the main data area expeditiously.
On this, select to replace the goal displacement district by putting according to the appendix in the replacement address process of using the main data area to carry out, can obtain and the aforesaid effect that does not have the identical performance improvement of the dish of replacing the district.
Much less, still in this case, comprise that the Write-once disc of replacing the district can realize the Data Update function, simultaneously and original the same the maintenance and the record-playback compatibility of the recording medium of common once writing recording medium and RAM and ROM type.Therefore, the file system that being generally general RAM type dish and ROM type dish provides can also be used to Write-once optical disc, and does not need to revise hardware and physical format.

1: the dish structure
At first, explain the CD that present embodiment provides.This CD can be realized by the CD-WORM that is called as so-called Blu-ray disc.Blu-ray disc belongs to the high density compact disc class.
The general physical parameter of the high density compact disc that this embodiment provides is explained as follows.
Explain the CD that this embodiment provides with the diameter of 120mm and the disc thickness of 1.2mm.That is to say that from the angle of outward appearance, the disc that present embodiment provides is similar to the dish of CD (read-only disk) system and the dish of DVD (Digital video disc) system.
As recoding/reproduction laser, use so-called blue laser.Have by use common 0.85 high NA optical system, the track space of common 0.32 micron little value is set, and the line density that the high value be generally 0.12 micron/every is set, about 23G byte of CD of diameter that can realize being used to having 12cm is to the storage of subscriber data capacity of 25G byte.
And, also developed two-layer dish.Two-layer dish is the CD with two recording layers.In the situation of two-layer dish, can realize the user data capacity of about 50G.
Fig. 1 is the synoptic diagram of layout (perhaps plot structure) that whole dish is shown.
Should be noted in the discussion above that in general system, can carry out format and handle with the layout shown in the layout shown in (a) that selectively realize Fig. 1 or Fig. 1 (b).
In either case, the recording areas of CD 1 is included in introducing district, the data field of intermediate circumference and the draw-out area of outermost circumference of inside circumference.
Introducing district, data field and draw-out area serves as record as described below and reproduces the district.Only reproduce the district at the pre-recorded information district PIC that introduces on distinguish the most inboard.The district that starts from introducing the management/control information district in district and end at the draw-out area is as only allowing data to write wherein once write-once district.
Only reproducing in district and the write-once district, the spirality track record forms wobble.Wobble is served as the rail of seeking in the rail processing of seeking of use laser spots and is indicated.Wobble becomes track record thus, and wherein data recording is read thereon or from it.
Should be noted in the discussion above that this embodiment adopts allows data to be recorded in CD on the groove.Yet scope of the present invention is not limited to the CD with this track record.For example, the present invention can also be applied to adopt the CD of convex region recording technique, and data are recorded in two convex regions between the adjacent groove thus.In addition, the present invention also can be applicable to adopt the CD of convex region/groove recording technique, and data are recorded on convex region and the groove thus.
In addition, the groove that is used as track record in CD has the shape by the swinging signal swing.Therefore, the disk drive that is used for this CD is from two marginal positions of the folded light beam detecting groove of the laser spots that is radiated groove.Then, by the fluctuation of the composition that fluctuates in the radial direction that is extracted in CD 1, can reproduce swinging signal as two marginal positions in the processing of moving laser spots along track record.
Modulate this swinging signal by information about the address of the record position on the track record.Information about the address comprises physical address and other additional information.Thus, producing the information about the address, disk drive can control address by the demodulation swinging signal, is recorded or reproduces at this address date.
Introducing district shown in Figure 1 is the district on the inboard of general 24mm radius.
The district that has the circumference of 22.2mm radius and have between the circumference of 23.1mm radius in introducing the district is pre-recorded information district PIC.
Pre-recorded information district PIC is used to store the swing state of an information reproduction as groove.Information reproduction comprises dish information, for example the information in the district on recoding/reproduction Power Supplies Condition, the CD 1 and be used for the information of copy protection.What should note is that these many information can also be recorded on the CD 1 as impressing pit (emboss pit) etc.
In some cases, not shown BCA (pulse cutting area (burst cutting area)) can be set up on the inboard of pre-recorded information district PIC.In BCA, be stored as CD 1 peculiar unique ID by burning (burn off) recording layer.This unique ID is that the record mark that produces with concentric circles is to form the record data of barcode format.
The district that has the circumference of 23.1mm radius and have between the circumference of 24.0mm radius in introducing the district is management/control information district.
Management/control information district has the fate form and writes district (OPC) and buffer zone to comprise control data zone, DMA (defect management), TDMA (temporary defect management area), test.
The control data zone that is included in management/control information district is used for record management/control information, such as disc-type, dish size, dish version, layer structure, channel bit length, BCA information, transfer rate, data field positional information, line speed record and recoding/reproduction laser power information etc.
Being included in test in management/control information district writes district (OPC) and is used for writing processing in that the test of carrying out is set in the data recording/reproducing condition in recoding/reproduction is handled the laser power of using.That is to say that it is the district that is used to adjust the recoding/reproduction condition that the district is write in test.
In the situation of common CD, the DMA that is included in management/control information district is used to write down the replacement address management information that is used for managing defect.In the disc system field, DMA is called defect management.Yet in the situation of the CD-WORM that present embodiment provides, DMA not only is used for the replacement address management information of recording defect but also management/control information of being used to write down the Data Update that is used to carry out CD.Therefore, DMA has the function of disc management area.
In addition, replace address process and carry out Data Update and become possibility by using, when new data more, also must upgrade the content of DMA in order to make.In order to upgrade the content of DMA, provide TDMA.
Replacement address management information is added and/or is recorded among the TDMA and constantly and is updated.
Last (up-to-date) replacement address management information that is recorded among the TDMA finally is sent to DMA.
To specifically describe DMA and TDMA in the back.
District on the circumference that has the radius in 24.0 to 58.0mm scope outside the introducing district is used as the data field.In fact user data is recorded to this data field and is reproduced from this data field.The start address ADdts of data field and end address ADdte are included in the data field positional information that is recorded in the aforementioned control data zone.
In (a) of Fig. 1, be the figure that represents wherein in the data field, to provide the form of replacing district (or spare area).In this case, replace OSA (outer spare area) on the outermost circumference that the district is configured to ISA (inner spare area) on the inside circumference of data field and data field.That is to say that each of ISA and OSA all is that the replacement district that uses is to handle defective and to replace address process to upgrade the data that have been recorded on the CD in replacing address process.
ISA be have the predetermined quantity that starts from the reference position in the data field bunch the district of size.1 bunch size is 65,536 bytes.
On the other hand, OSA be have from the data field last position to the predetermined quantity of inboard bunch the district of size.The size of ISA and OSA is recorded among the above-mentioned DMA.
Be present in district as the centre of the data field that is clipped in the district between ISA and the OSA as user data area.Usually record user data up in this user data area and usually and read user data from this user data area.
Also be recorded among the above-mentioned DMA position of representing user data area according to the start address ADus and the end address ADue of user data area.
On the other hand, in (b) of Fig. 1, be to be illustrated in the figure that the form of replacing district (perhaps spare area) is not set in the data field.In this case, almost the whole district of data field all is used as user data area.Yet, can produce ATDMA (additional TDMA) in the end edge of data field.Should be noted in the discussion above that and in the situation of the layout shown in (a) of Fig. 1, can in OSA, produce ATDMA.
ATDMA is the district that additionally is provided to the TDMA in management/control information district.Run out if be used to upgrade the TDMA that replaces address management information, be used to upgrade the continuity that the ATDMA that replaces address management information can be used as TDA so.
In the situation of the form shown in (b) of Fig. 1, do not provide ISA and OSA.Therefore, in above-mentioned DMA, the size of ISA and OSA all is set to 0.
The position of user data area, just start address ADus is consistent with the start address ADdts of data field.If ATDMA is not provided, the end address ADdte of the end address ADue of user data area and data field is consistent so.On the other hand, if ATDMA is provided, the end address ADue of user data area is consistent with the address that was right after before AtDMA so.
At the form shown in (a) of Fig. 1 or in the situation of the form shown in (b) of Fig. 1, the zone on the circumference of the radius data field outside, that have 58.0 to 58.5mm scope is the draw-out area.The draw-out area is the management/control information district with predetermined format, to comprise control data zone, DMA and buffer zone.More as being included in the control data zone of introducing in the district, the control data zone of draw-out area is used to store inhomogeneous management/control information.With identical symbol, more as being included in the DMA that introduces the district, the DMA of draw-out area is with the district of the management information of the management information of the ISA that notes down and OSA.
Fig. 2 is the figure of the typical structure in expression management/control information district.
As shown in FIG., except undefined part (part of reservation), introduce the district and comprise a plurality of districts, for example DMA2, OPC (district is write in test), TDMA and DMA1.On the other hand, except undefined part (reserve part), the draw-out area comprises a plurality of districts, for example DMA3 and DMA4.
Should be noted in the discussion above that not shown in the drawings above-mentioned control data zone.This is because in fact, for example, the part of control data zone is used as DMA.Because the structure of DMA is main points of the present invention, so not shown in the drawings control data zone.
As mentioned above, introduce district and draw-out area and comprise four DMA, promptly DMA1 is to DMA4.Each all is used as the district of the identical replacement of record address management information to DMA1 to DMA4.
Yet, provide TDMA to replace the district of address management information as being used for blotter, and each because Data Update or because defective is carried out when replacing address process, new replacement address management information is recorded in (if perhaps TDMA has used up then has been ATDMA) among the TDMA with being incremented and has been recorded in wherein information with renewal.
Therefore, for example, by finalization (finalize), do not use DMA up to CD 1.On the contrary, carry out to replace address process and add to new replacement address management information among the TDMA (perhaps ATDMA) and/or be recorded among the TDMA (, then being ATMDA) if perhaps TDMA uses up.When CD 1 was finally changed, the replacement address management information that is recorded in recently on the TDMA (or ATDMA) was sent to DMA, so that can carry out the replacement address process according to DMA.
2:DMA
Fig. 3 is that expression is recorded in the structural drawing of introducing the DMA in district and the draw-out area.
The figure shows general DMA with size of 32 bunches.Yet the size of DMA is not limited to 32 bunches.
Should be noted in the discussion above that 1 bunch is aforesaid 65,536 bytes.It bunch is least unit with the processing of data recording to the dish.Sector or Frame are the another kind of units with size of 2048 bytes.Therefore, bunch constitute by 32 sectors or 32 Frames.When the size of expression user data, the sector equals Frame.Yet the sector is a physical data unit, and Frame is a logical data unit.
Distribute the address for each sector.Physical sector address is called PSN (physical sector number), yet logical sector address is called LSN (logic sector number).
In typical structure shown in Figure 3, in scope 1 to 32, bunch number be assigned to per 4 bunches of numberings of 32 bunches as the position of each data among the indication DMA.Bunch to express the size of each data.In this case, each data has 4 bunches size.
In DMA, bunch number 1 to 4 sign is formed for writing down four bunches of section (segment) of DDS (dish definition structure), its specific descriptions dish.
With in the back by being described with reference to Figure 4 the content of DDS.In fact, because the size of DDS is one bunch, so in this section, write down four identical DDS.
Bunch numbers 5 to 8 signs are formed for writing down four bunches of section of DFL#1, and it is the first record area of DFL (defect list).The size that is stored in the data in this defect list is four bunches that form about the tabulation of the information of replacing the address.Be called as DOW clauses and subclauses or DFL clauses and subclauses about the information of replacing the address.Will be described later these clauses and subclauses.
Bunch numbers 9 to 12 signs are formed for writing down four bunches of section of DFL#2, and it is second record of defect list.
The second record area back be the 3rd and recording areas DFL#3 subsequently to DFL#6, each recording areas all has four bunches size.By four bunch the section DFL#7 of bunch number 29 to 32 signs as the 7th recording areas of defect list.
Obviously visiblely from top description be, the DMA with size of 32 bunches comprises the recording areas of seven defect lists, that is, DFL#1 is to DFL#7.
Allowing data recording therein in once the CD-WORM, this is the situation with CD 1 that present embodiment provides, and in order to write down the content of DMA, must carry out the processing that is called " finalization (finalize) ".In this case, in DFL#7, write down identical content at seven recording areas DFL#1.
Because the structure of defect list DFL is almost the same with the structure of TDFL (interim DFL) among the described TDMA in back, so omit explanation to the structure of defect list DFL.
Fig. 4 is the figure of data structure of content of DDS that is illustrated in the starting point place record of DMA shown in Figure 3.
As mentioned above, DDS has the size of bunch (=65,536 byte).
In the data structure of Fig. 4, byte 0 is the position of starting point of DDS with size of 65,536 bytes.The quantity that is included in the byte in each data content is shown in the byte number tabulation.
Two bytes by byte location 0 to 1 indication are used as the byte that is used for record " DS ", and it is that this bunch of indication is the DDS identifier of DDS.
The byte that is used as the DDS form numbering of the version that is used to write down the DDS form by a byte of byte location 2 indication.
Be used as the byte that is used to write down the number of times that DDS has been updated by four bytes of byte location 4 to 7 indication.The number of times that DDS has been updated is called DDS and upgrades number.Should be noted in the discussion above that in this embodiment, in finalization processing, replace address management information and additionally be written among the DMA itself, rather than be used to upgrade DMA.Before the DMA in being written to finalization processing, replace address management information and be stored among the TDMA.Thereby when final execution was finally changed processing, the TDDS of TDMA (interim DDS) comprised the number of times that TDDS has been updated.The number of times that above-mentioned DDS has been updated is the number of times that TDDS has been updated.
Four bytes by byte location 16 to 19 indications are used as the byte that is used to write down AD_DRV, and described AD_DRV is the beginning physical sector address in the driving district among the DMA.
Four bytes by byte location 24 to 27 indications are used as the byte that is used to write down AD_DFL, and described AD_DFL is the beginning physical sector address of defect list DFL among the DMA.
The byte that is used as the PSN (physical sector number or physical sector address) of the starting position of the user data area that is used for recorded data zone by four bytes of byte location 32 to 35 indications.The starting position of the user data area in the data field is the A Dus shown in Fig. 1.That is to say that these four bytes are used as and are used for the byte that the PSN (physical sector number) of the position with LSN (logic sector number) 0 indicated in record.
The byte of LSN that is used as the end position of the user data area that is used for recorded data zone by four bytes of byte location 36 to 39 indication.The end position of the user data area in the data field is the ADue shown in Fig. 1.
The byte that is used as the size of the ISA that is used for recorded data zone by four bytes of byte location 40 to 43 indications.In the situation of form shown in (b) of Fig. 1, the size of ISA is set to 0.
The byte that is used as the size of each OSA that is used for recorded data zone by four bytes of byte location 44 to 47 indications.In the situation of form shown in (b) of Fig. 1, the size of OSA is set to 0.
The byte that is used as the size of the ISA that is used for recorded data zone by four bytes of byte location 48 to 51 indications.This ISA is the ISA on the second layer of two-layer dish.
By a byte of byte location 52 indication be used as be used for the record sheet registration can be according to whether by using the byte of the spare area all mark (spare area full flag) that ISA or OSA upgrade.That is to say that the spare area all mark is used to represent that ISA and OSA are used up fully.
A byte by byte location 54 indications is used as the byte that is used for indicator identification marking (certification flag).Therefore, this byte is the discriminating state of CD 1.
The byte that is used as the address pointer that is used to write down last affirmation by four bytes of byte location 56 to 59 indication.
Byte location outside the above-mentioned byte location is retained (or undefined) and is all filled by code 00h.
In DMA, replace address management information and be recorded in the aforesaid data structure.Yet, as mentioned above, these kinds of information of record in the processing of finalizing disc 1.In this is handled, will be delivered to DMA from TDMA about the up-to-date information of replacing address administration.
Be recorded among the following TDMA and be updated frequently about the information of the information of defect processing and the relevant replacement address process of carrying out owing to Data Update.
3:TDMA
3-1:TDMA structure and TDMS updating block
The TDMA that provides in explanation management as shown in Figure 2, shown in Figure 1/control information district is described below.The spitting image of DMA, TDMA (interim DMA) is used to store about replacing the district of address information of managing.When in Data Update or defects detection, carry out when replacing address process, upgrade TDMA by incrementally writing down about the additional information of replacing address administration.
Fig. 5 A is the figure of the structure of expression TDMA to 5D.Shown in Fig. 5 A and 5B, the typical sizes of the TDMA that provides in management/control zone is 2048 bunches.
Fig. 5 C is the figure of structure of TDMA that expression has 2048 bunches size.Yet the structure shown in Fig. 5 C is corresponding to the form of replacing district ISA and OSA that comprises as shown in Fig. 1 (a).With in the back by being described with reference to Figure 16 TDMA structure corresponding to the form shown in Fig. 1 (b).
At preceding 2 bunches of TDMA starting point place, promptly bunch CL0 and CL1 have the function of TDMA indicator.
Bunch CL1 is the ATDMA indicator, and when information was recorded among the ATDMA (additional TDMA) for the first time, it was used to write down the structure that comprises the up-to-date TDDS (temporary disk (T-disk) definition structure) that will be described later.
Bunch CL0 is the DMA indicator, and when data were recorded among the DMA, it was used for the necessary information that reads from the up-to-date TDMS (temporary disk (T-disk) management structure) that will be described later with form record shown in Figure 3.
Utilize the structure that has been recorded among bunch CL1, this bunch indication can be read up-to-date TDMS from ATDMA.Utilize the necessary information be recorded among bunch CL0, this bunch indication CD 1 is finally changed, and is placed in the write-protect state and can reads up-to-date information about CD 1 from DMA.
Bunch CL2 to CL2047 is used to upgrade about the information of CD 1 with about replacing the address information of managing.
Comprise about the information of CD 1 with about the structure of replacing the address information of managing being called TDMS (temporary disk (T-disk) management structure), these information be recorded in bunch CL2 and subsequently bunch in.
Upgrade TDMS among the TDMS by incrementally additional information being recorded with the TDMS updating block, each all has the size that arrives individual bunch of N in scope 1 described TDMS updating block.In continuous recording pattern (sequentialrecording mode), the value of N is set to 4.In the situation of 2 layers of dish, the value of N is set to 8.
In the situation of the TDMS shown in Fig. 5 D, for example, the initial TDMS updating block that record has 1 bunch size in bunch CL2.Then, the 2nd TDMS updating block that record has 1 bunch size in bunch CL3.Subsequently, the 3rd TDMS updating block that record has 2 bunches size in bunch CL4.
Owing to must be updated about the information of CD 1 with about replacing the address information of managing, thus by every now and then as mentioned above the other TDMS updating block of incremental record in follow-up bunch, and upgrade TDMS continuously.Up-to-date TDMS updating block be recorded to be right after after as described below bunch bunch in: in this bunch, write down the and then TDMS updating block of front.
If the continuous recording pattern is set to the logging mode according to the Write-once disc of this embodiment, TDMS is made of three unit so, i.e. TDDS (temporary disk (T-disk) definition structure), TDFL (temporary defect list) and SRRI (continuous recording range information).These unit always are recorded among the identical TDMA.
As will be specifically described in the back, TDDS be used for the structure that essential record is used for the information of managing of TDMS, and TDFL illustrates the DOW of the replacement address information of representing reality and the tabulation of DFL clauses and subclauses.On the other hand, SRRI is SRR (continuous recording scope) management information that is recorded in the user data area.Continuous recording scope in this case is corresponding to being called the especially track of CD and DVD.
Fig. 6 A is the figure that represents the structure of TDMS updating block respectively to 6C.Each TDMS updating block comprises the TDDS of the size with 1 sector.TDDS be placed in by the TDMS updating block constitute bunch in last sector (perhaps last Frame) in.
If the TDMS updating block comprises TDFL, TDFL occupies required a plurality of sectors (perhaps a plurality of Frame) at TDMS updating block starting point place so.
If the TDMS updating block comprises SRRI, SRRI is placed on a plurality of sectors of end of TDMS updating block so.Particularly, SRRI occupied required a plurality of sectors (perhaps a plurality of Frame) before being right after TDDS.
Fig. 6 A is the figure that expression comprises the general TDMS updating block of SRRI and TDDS.This typical case TDMS updating block has 1 bunch general size, and last sector (perhaps last Frame 31) is used to write down TDDS.SRRI has the size of M sector.That is to say that M the sector that was right after before TDDS is used to write down SRRI.This M sector starts from Frame (31-M) and ends at Frame 30.
Because this general TDMS updating block does not comprise TDFL, so Frame 0 is filled the remainder according to 00h to Frame (30-M).
Fig. 6 B is the figure that expression comprises the general TDMS updating block of TDFL and TDDS.This general TDMS updating block has general K bunch size, and last sector is used to write down TDDS.In this case, last sector is the Frame 31 of bunch K.If TDFL has the size of N sector, be used to store TDFL in N sector of the section start of TDMS updating block so.This N sector is the Frame from bunch 0 Frame 0 to the scope of the Frame (x-1) of bunch K, and wherein symbol x is the integer that satisfies following equation:
x=mod(N/32)-1
Because this general TDMS updating block does not comprise SRRI, so Frame x is filled the remainder according to 00h to Frame 30.
Fig. 6 C is the figure that expression comprises the general TDMS updating block of TDFL, SRRI and TDDS.This general TDMS updating block has general K bunch size, and last sector is used to write down TDDS.In this case, last sector is the Frame 31 of bunch K.If TDFL has the size of N sector, be used to store TDFL in N sector of the section start of TDMS updating block so.This N sector is to bunch Frame of the scope of the Frame of (K-1) (x-1) from bunch 0 Frame 0.
SRRI has the size of M sector.That is to say, be right after TDDS M sector before and be used to write down SRRI.This M sector starts from the Frame (31-M) of bunch K and ends at the Frame 30 of bunch K.
If as shown in the figure, between TDFL and SRRI remaining area, this zone is filled the remainder according to 00h so.
Should be noted in the discussion above that constitute the TDMS updating block bunch quantity with the change in size of TDFL and SRRI.
Fig. 7 is the figure that represents wherein incrementally to have write down the state of additional TDMS updating block.For example, at first, incrementally record has the additional TDMS updating block #1 of 2 bunches size.Then, incrementally increase additional TDMS updating block #2, #3...#x...#y.
For example, supposing must renewal TDFL, SRRI or TDFL and SRRI.In order to upgrade TDFL, incrementally write down additional TDMS updating block with the structure shown in Fig. 6 B.In order to upgrade SRRI, incrementally record has the additional TDMS updating block of the structure that Fig. 6 A shows.In order to upgrade TDFL and SRRI, incrementally write down additional TDMS updating block with the structure shown in Fig. 6 C.If must upgrade SRRI rather than TDFL, for example, incrementally Ji Lu additional TDMS unit has form as shown in Figure 6A.
In state shown in Figure 7, TDMS updating block #y is up-to-date TDMS updating block.As shown in the drawing, the TDMS unit always comprises TDDS.Thereby the TDDS that is included among the TDMS updating block #y is effective up-to-date TDDS.
This up-to-date TDDS points to effective SRRI and effective TDFL.
TDMS updating block #y in this example writes down to upgrade SRRI with being incremented.Therefore, the up-to-date TDDS that is included among the TDMS updating block #y makes the SRRIn that is included among the TDMS updating block #y become effective SRRI.
And if the TDFLm that is included among the TDMS updating block #x is effective TDFL, the up-to-date TDDS that is included among the TDMS updating block #y makes the TDFLm that is included among the TDMS updating block #x become effective TDFL.
That is to say, Fig. 5 A in the TDMA shown in the 5D bunch CL2 and subsequently bunch in, every now and then in the TDMS updating block of incremental record, the TDDS that is included in the up-to-date TDMS updating block is effective up-to-date TDDS, points to effective SRRI and effective TDFL.
3-2:TDDS
Fig. 8 is the figure that expression is recorded in the structure of the TDDS (temporary disk (T-disk) definition structure) in last sector of aforesaid TDMS updating block.
That is to say that TDDS has the size of 1 sector that equals 2048 bytes.DDS has the content of the content that is similar in front the DDS among the DMA that describes with reference to figure 4.Have 1 bunch the size that equals 65,536 bytes although should be noted in the discussion above that DDS, as the explanation of earlier in respect of figures 4, only the byte location 0 to 59 of Frame 0 is defined as the actual content of DDS.That is to say that the actual content of DDS is recorded in first sector (perhaps first Frame) of this bunch.Given this, although TDDS has the only size of 1 sector, in TDDS, can hold the actual content of DDS.
As mentioned above, TDDS is in last sector of last bunch of TDMS updating block.Therefore, as shown in Figure 8, TDDS is recorded on the byte location 0 to 2047 of Frame 31.
The byte location 0 to 53 of TDDS is identical with the byte location of DDS.That is to say, when finalization, write down DDS, in the DDS of record, reflect the content of the byte location 0 to 53 of up-to-date TDDS.
Should be noted in the discussion above that the byte location 4 to 7 in the byte location 0 to 53 of DDS and TDDS is used to store the DDS-renewal number that earlier in respect of figures 4 is described.Yet in the situation of TDDS, the information that is stored in the byte location 4 to 7 is that TDDS produces counting.And, the defect list that is recorded in byte location 24 to 27 is begun PSN remain on 0, close processing (close processing) up to what carry out CD 1.Closing processing is the processing of forbidding that above-mentioned incremental record is handled.
In closing processing, the defect list that the TDDS that is recorded in byte location 4 to 7 produces counting and is recorded in byte location 24 and 27 begins PSN and is copied to byte location 4 to 7 and the byte location 24 to 27 that is written into the DDS the DMA respectively from up-to-date TDDS at finalization point.
Byte location 1,024 among the TDDS and byte location subsequently are used for being recorded in the non-registering information of DDS.Should be noted in the discussion above that in TDDS shown in Figure 8, some contents of byte location 1,024 and subsequently byte location deleted and only illustrate with this embodiment by the relevant content of interpretation process.
The logging mode that is used for recording disk 1 in a byte at byte location 1,024 place.
Four bytes at byte location 1,032 to 1,035 are used to write down wherein the last physical sector address PSN of the user data area of record data.
The size that is used to write down ATDMA in four bytes of byte location 1,040 to 1,043.
A PSN of first bunch who is used to write down TDFL in four bytes of byte location 1,120 to 1,123.
Thereafter per 4 bytes are used to store second to the 8th bunch of TDFL each a PSN.
A PSN of first bunch who uses TDFL is to the 8th bunch the PSN conduct of TDFL their indicator separately bunch to TDFL.As shown in Figure 7, indicator is used in reference to and shows effective TDFL.
A PSN who is used to write down SRRI in four bytes of byte location 1,184 to 1,187.The PSN of this SRRI points to SRRI and is used to indicate as shown in Figure 7 effective SRRI.
Four bytes of byte location 1,216 to 1,219 are used to write down next available PSN of ISA.
Four bytes of byte location 1,220 to 1,223 are used to write down next available PSN of OSA.
In replacing address process, use after ISA or the OSA, the PSN of next available sector in ISA or OSA be respectively stored in 4 bytes of byte location 1,220 to 1,223 or in 4 bytes of byte location 1,220 to 1,223 as renewal.
The byte of byte location 1,920 to 2,048 is used for storing driver ID.
3-3:TDFL
Below, the structure of explanation TDFL (interim DFL).As mentioned above, by in additional TDMS updating block, comprising that new TDFL upgrades TDFL.
In TDFL structure shown in Figure 9, bunch number/the data frame number be among the TDFL bunch numbering and by this bunch number sign bunch in the numbering of sector of 2,048 bytes.The Frame byte location is by the byte location in the Frame of data frame number sign.
64 bytes that start from the byte of byte location 0 are used to store TDFL (temporary defect list) header of the management information of describing TDFL.
The TDFL management information that is included in the TDFL header comprises that this bunch of indication is the entry number of the number of entries in TDFL bunch information, version number, TDFL renewal number (perhaps TDFL record/renewal number) and the message block of indicating TDFL.Clauses and subclauses are DOW (data rewrite) and DFL clauses and subclauses.
The byte of byte location 64 and byte location subsequently is used for the interim tabulation of storage defect.The interim tabulation of defective comprises a plurality of message block, and each all has the size of 8 bytes described message block.If N message block is included in the interim tabulation of this defective, the size of this tabulation thereby be N * 8 byte then.
Message block with size of 8 bytes is one and replaces the address breath, serves as DOW or DFL clauses and subclauses.
Basically, the DOW clauses and subclauses are replacement address informations identical with the DFL clauses and subclauses.Explain that for convenience the DFL clauses and subclauses are replacement address informations of defect area, and the DOW clauses and subclauses are to be used for the more replacement address information of new data.
Owing in fact handle DOW and DFL clauses and subclauses with identical replacement address process, thus these clauses and subclauses can with the message block coexistence in the interim tabulation of defective.
Thereby the interim tabulation of defective is the set of a plurality of DFL and DOW clauses and subclauses.The maximum quantity of DFL and DOW clauses and subclauses is 32,759 under the situation of one deck dish.
The temporary defect list terminal point that also has the size of 8 pieces is closelyed follow after the interim tabulation of defective.The end point of the interim tabulation of temporary defect list terminal point indication defective.Be filled data 0 with the district in the temporary defect list terminal point same cluster, up to the end of this bunch.
Figure 10 A is the figure of structure of the DOW clauses and subclauses of expression 8 bytes of serving as message block.Should be noted in the discussion above that the DFL clauses and subclauses have the form identical with the DOW clauses and subclauses.
Therefore, the DOW clauses and subclauses have 64 size.Four b63 are used for recording status 1 to b60.
28 position b59 are used to record to b32 and replace the target source address, promptly replace a PSN of target source bunch.Replacing the target source address is such address, and wherein supposition has just been write down data in this address at first, but replaces with the address of replacing the another location in the address process.Be used for substituting the address of replacing the target source address and be called as replacement goal displacement address.
Four position b31 are used to recording status 2 to b28.
28 position b27 are used to record to b0 and replace the goal displacement address,, replace a PSN of goal displacement bunch that is.
Implication with reference to the following description status 1 of figure 10B and 2.
The state 1 and the state 2 expression DOW clauses and subclauses (perhaps DFL clauses and subclauses) that all are set to " 0000 " are common replacement address informations.
In the situation of common replacement address information, these clauses and subclauses corresponding to performed, according to replacing the target source address and replace the replacement address process that handle bunch the goal displacement address, described replacement target source address and replace the goal displacement address and be recorded in the clauses and subclauses of replacing address information.That is to say, these clauses and subclauses corresponding to performed, according to the detection of defective new data or replace the replacement address process of address process more.
Under the situation of the form that comprises the replacement district that is provided with as shown in Fig. 1 (a), replacement goal displacement address is the address among ISA or the OSA basically.On the other hand, under the situation that does not comprise the form of replacing the district as shown in Fig. 1 (b), replacing the goal displacement address is selected address in user data area.
Should be noted in the discussion above that as will be described in the back, in some cases, even, also can carry out the replacement address process by using the zone in user data area for the form in the replacement district that is provided with shown in (a) that be included in Fig. 1.In these situations, replacing the goal displacement address is the address of selecting in user data area.
The state 1 and 2 that is set to " 0000 " and " 0001 " represents that respectively clauses and subclauses are included in burst (burst) piece and replace the start address of using in the address process.Be arranged on 1 and 2 of " 0000 " and " 0010 " state and represent that respectively clauses and subclauses are included in burst block and replace the end address of using in the address process.This processing is to the continuous bunch replacement address process of upward carrying out of a plurality of physics of being handled jointly.
That is to say, have 1 and 2 the clauses and subclauses that are arranged on " 000 " and " 0001 " state comprise respectively be used as one replace target source bunch and common a plurality of physics of handling continuous bunch a PSN of first bunch and be used as one replace goal displacement bunch and common a plurality of physics of handling continuous bunch a PSN of first bunch.
Have 1 and 2 the clauses and subclauses that are set to " 0000 " and " 0010 " state comprise respectively as one replace target source bunch and common a plurality of physics of handling continuous bunch last cluster a PSN and be used as one replace goal displacement bunch and common a plurality of physics of handling continuous bunch a PSN of last cluster.
By using above-mentioned two clauses and subclauses, the clauses and subclauses that promptly have respectively the state 1 that is set to " 000 " and " 0001 " and 2 with have respectively the state 1 that is set to " 0000 " and " 0010 " and 2 clauses and subclauses, can to each and a plurality of physics of being handled jointly in target source and the displacement as an alternative bunch continuous bunch carry out the replacement address process.That is to say, for to each and a plurality of physics of being handled jointly in target source as an alternative and the displacement bunch continuous bunch carrying out replace address process, needn't replace target source and replace goal displacement clauses and subclauses bunch are provided for every pair.On the contrary, only need to replace target source and displacement and bunch provide to replace the address data entries and to replace target source and displacement and bunch provide another to replace the address data entries for first for last.
DOW co-exists on the TDFL with identical form with the DFL clauses and subclauses.Yet, when the CD 1 according to present embodiment was placed on the device with data replacement address processing power, DOW and DFL clauses and subclauses all were interpreted as DFL clauses and subclauses, result, since the recovery time read bunch stand to replace normally address process, so keep reproduction compatibility.
In addition, must consideration not have the device that burst block is replaced the address processing capacity.Therefore, when writing DMA in the finalization time, promptly when when the finalization time writes the content of up-to-date TDFL among the DFL, must be according to they common replacement address data entries separately, finish burst block by expression and replace a plurality of bunches of address process and rebuild DFL.According to they common replacement address data entries separately, finish burst block by expression and replace a plurality of bunches of address process, each common replacement address information of all describing bunch that all replace the address informational clusters also can guarantee reproduction compatibility even make not having under the situation of device that burst block replaces the address processing capacity.
3-4:SRR and SRRI
Below, explain SRR (continuous recording scope) and SRRI (continuous recording range information).
Figure 11 A is the figure of the structure of expression SRR to 11C.SRR write area (perhaps continuous recording scope) uses this write area when adopting the continuous recording pattern in according to the Write-once disc of present embodiment.SRR has following characteristic<1 of the track that is similar on the CD〉to<5 〉.
<1〉with on the SRR of data recording in the address direction that increases.And SRR can only have the recorded data address that is called appendix measuring point (postscript-recording point).Also be called as NWA (next can write the address) or next can write PSN as the address of appendix measuring point.The appendix measuring point of SRR thus be remaining in SRR, as the start address in the district in district that can record data.
Shown in Figure 11 A, LRA (last recording address or last PSN) is the address of the last record among the SRR.In the explanation, the meaning of the address of record is the address of record data on it below.In this case, can be with the following NWA that represents:
NWA=(ip(LRA/32+1)*32+1)(LRA≠0)
The initial PSN (LRA=0) of NWA=SRR
Wherein ip (N) is the maximum integer less than N.
That is to say, if data are recorded among the SRR, then NWA be follow closely comprise LRA bunch after bunch start address (PSN).On the other hand, if there are not data to be recorded among the SRR, then NWA is set at the start address (PSN) of SRR.
<2〉SRR can have one of two states, that is to say, perhaps open mode or closed condition.
Figure 11 A is the figure of the SRR that opens of expression, and it is writeable SRR or the SRR with NWA.On the other hand, Figure 11 B is the figure of the SRR that closes of expression, and it is SRR that can not write or the SRR that does not have NWA.
<3〉on dish, distribute the processing of the SRR that opens to be called the processing that keeps SRR.On the other hand, the processing that the state of the SRR that opens is become closing state is called the processing of closing SRR.
<4〉may reside on the dish up to peaked a plurality of SRR of 7927.The SRR that is present on the dish can comprise that each all has the SRR of open mode up to 16.
<5〉SRR that can select data to be written into arbitrarily in any order.
According to the practical methods of using SRR, after file data being recorded on the CD 1, the directorial area by allocate file system on the direction of file data and the management information of file system recorded keep the SRR that opens in the treatment region.
Figure 11 (c) is that expression is with the figure of continuous recording pattern with the example layout of data recording dish thereon.
On CD 1,4, SRR, promptly SRR#1 exists to SRR#4.Each is the SRR that opens for SRR#1, SRR#3 and SRR#4, and SRR#2 is the SRR that closes.
Therefore, on any of next write address NWA1, NWA3 of SRR#1, SRR#3 and SRR#4 and NWA4, additional data can record on the CD 1 with being incremented respectively.
Above-mentioned TDMS updating block writes down to store additional SRRI, as the information that is used to manage these SRR with being incremented.
Figure 12 is the figure of the structure of expression SRRI.
As shown in the figure, SRRI has the size of scope 1 to 31 Frame.
Relative data frame number in the structure shown in Figure 12 is the numbering of Frame in the identification bunch, and as previously described, SRRI is placed in the locational TDMS updating block before the TDDS that is right after in last Frame 31 that is recorded in this unit.For example, suppose that SRRI has the size of M sector.In this case, SRRI is placed in Frame (31-M) on 30.Byte location in the Frame is the position of the byte in the Frame.
64 bytes that start from the byte of SRRI section start are used as the SRRI header of the management information that is used to describe SRRI.
Be included in SRRI management information in the SRRI header comprise indication bunch be SRRI bunch information, version number, SRRI upgrade number (perhaps SRRI record/renewals number) and indicate the entry number of the sum of SRR clauses and subclauses, they each all is the piece of the SRR information among the SRRI.
The byte of byte location 64 and byte position subsequently is used to store the tabulation of SRR clauses and subclauses.The tabulation of SRR clauses and subclauses comprises a plurality of SRR message block, they each all have the size of 8 bytes.If N message block is included in the tabulation of SRR clauses and subclauses, Lie Biao size thereby be N * 8 byte then.
The SRRI tabulation terminal point that also has the size of 8 bytes is closelyed follow after the interim tabulation of SRR clauses and subclauses.Follow after SRRI tabulation terminal point up to bunch the district of end be filled data 0.
Figure 13 A is the figure of the structure of expression SRRI header.
2 bytes at byte 0 and 1 place are used to write down the SRRI-ID (SRRI identifier) as the management information of SRRI.
1 byte at byte location 2 places is used to the SRRI form that record sheet is shown as the version number of SRRI.
The SRRI that 4 bytes at byte location 4 to 7 places are used to write down the number of times of representing that SRRI up to the present has been updated upgrades number.
Be used to write down the SRR entry number of the sum of the SRR clauses and subclauses among the expression SRRI in 4 bytes at byte location 12 to 15 places.
1 byte at byte location 16 places be used to record sheet be shown among the SRRI each all have open mode the quantity of opening SRR open the SRR number.
The byte that originates in the byte at 20 places, position is used to write down the tabulation of opening SRR numbering and opens the set of the numbering of SRR as among the SRRI all.
Figure 13 B is the figure of the structure of the expression tabulation of opening SRR numbering.Each opens the size that the SSR numbering has 2 bytes.Can comprise that opening SRR up to 16 numbers owing to open the tabulation of SRR numbering, so this tabulation has the size of 32 bytes.If open SSR numbering less than 16, open so that the SRR numbering does not occupy, be filled data 0 as the district of the remaining area of tabulation.With the order that reduces to opening the SRR number sorting in the tabulation.When the quantity of the SRR that opens increases or reduces, correspondingly adjust the content of tabulation.
As shown in figure 12, in SRRI, the tabulation of SRR clauses and subclauses is followed after this SRRI header.Figure 14 is the figure of the structure of expression SRR clauses and subclauses.Symbol i shown in the figure is the numbering of distributing to corresponding to the SRR clauses and subclauses of SRR.
Expression has 8 bytes or 64 s' size about the SRR clauses and subclauses of the SRR of the information of SRR, and it is described as follows.
4 position b63 are positions that be retained or undefined to b60.
28 position b59 are used to write down the start address that is present in the SRR#i in the user data area to b32, i.e. the PSN of the starting point of the starting cluster of SRR#i.
Position b31 is used to whether record indication SRR is the conversation start position of the initial SRR of session (session).Particularly, being set to a position b31 indication SRR of 1 is the initial SRR of session.That is to say that this session is from this SRR.
3 position b30 are positions that be retained or undefined to b28.
28 position b27 are used to write down the LRA (Ji Lu address at last) that is present in the SRR#i in the user data area, the i.e. PSN of the end of SRRI#i as shown in figure 11 to b0.
Comprise that the SRRI of aforesaid SRRI header and SRR clauses and subclauses is used to manage the address of the numbering of each SRR, the SRR that are present in the user data area, each SRR and the LRA of each SRR.In addition, as mentioned above, can calculate the NWA (next writeable address) that opens SRR from the LRA the SRR clauses and subclauses that provide for SRR are provided (Ji Lu address at last).
For example when SRR is retained,, so data are incrementally recorded in the district of the NWA that starts from SRR or SRR is closed if must upgrade the supervisor status of SRR.By in the TDMS of incremental record updating block, comprising SRRI, use SRRI to upgrade this state.
3-5: the replacement address process that is used to have the form of replacing the district
Below interpretation be used to comprise the basic replacement address process that the form in district is replaced in the predistribution of the form of ISA shown in Fig. 1 (a) and/or OSA.
As shown in figure 15, ISA (the inner district that is equipped with) and/or OSA (outer spare area) are distributed in the inboard and the outside of data field respectively, as the replacement district that is used to carry out the replacement address process that is used for defect cluster.
In addition, when existence writes data into the request of processing of the address of having write down, that is to say, the more request of the data of new record, each also uses ISA and/or OSA and acts on the replacement district of the actual data recording that will be written into to destination address.The address of having write down is the address of record data, otherwise unwritten address is the address of record data not on it.
The size of ISA and OSA is defined among DDS and the TDDS, and this described in the above.
When initialization, determine the size of ISA, and remaining unchanged thereafter.
The replacement address process of ISA and OSA is used in execution as described below.With Data Update as an example.For example suppose, exist with data write user data area bunch in the address of having write down in request, promptly be used for upgrading the request of the data that are recorded in bunch.In this case, because CD 1 is CD-WORM, data can not be written in such bunch of CD 1.Therefore, be written to the actual ISA of being recorded in of data of the address of having write down or OSA bunch in.Actual data recording is called as the replacement address process to the processing of the address of having write down.
Replace address process and managed into above-mentioned DOW clauses and subclauses.That is to say, record data bunch the address be listed in the DOW clauses and subclauses target source address as an alternative, and as record data in fact bunch, be included among ISA or the OSA bunch the address be listed in same DOW clauses and subclauses goal displacement address as an alternative.
That is to say, in the situation of Data Update, in fact the data that are used for replacing the data that write down are written to ISA or OSA, and the replacement target source that is used for Data Update and displacement position are managed the DOW clauses and subclauses on the TDFL that becomes to be recorded in TDMA.By this way, even CD 1 is a Write-once disc, in fact also can upgrade the data that are recorded on this CD 1, that is to say, more to wait for the file system of this operating system or this host computer system or this document system be attainable in the processing of new data.
Also, can also carry out above-mentioned replacement address process for the purpose of managing defect.In replacing address process, when the defect area that detects on CD, the data that be written to this defect area in fact be stored ISA or OSA bunch in.Then, in order to replace the purpose of address process management, list DFL clauses and subclauses.
In replacing address process, data by physical record start from increasing progressively lowest address place on the address direction bunch ISA bunch in.When all bunches of this ISA run out, as shown in figure 15 OSA bunch proceeded to replace address process.The actual ISA that writes data and OSA bunch are called as and replace the goal displacement position in replacing address process.
Say at will that with this form, the partly or completely district that can utilize OSA is as ATDMA (additional TDMA).
Should be noted in the discussion above that in the situation of the preferred embodiment in comprising the form of replacing the district as mentioned above, even after the replacement district all runs out, also can carry out the replacement address process by using user data area, this will be described later.
3-6: TDMA and ATDMA in the form of not replacing the district
Figure 16 represents neither to comprise that ISA does not comprise the figure of the dish layout of OSA yet.
Use special format command to produce and do not comprise the dish of replacing the district.Because CD 1 does not comprise common replacement district, so the parameter of this order can be distributed the address with appointment maximum storage capacity is set.Be set to be slightly less than the value of maximum storage capacity by parameter clearly, can expand the function of the disk drive that serves as data recording/reproducing device, so that stay next district as not to the district that wherein distributes the address at the end of user data area.In this embodiment, this district is called the standby treatment region that can be used as ATDMA.
In the situation that comprises the form of replacing the district, the synchronous TDMA indicator as providing at the TDMA section start uses 2 bunches of CL0 and CL1 as shown in Figure 5.On the other hand, in the situation that does not comprise the form of replacing the district, another bunch is added to the TDMA indicator to provide 3 bunches of CL0, CL1 and CL2.Bunch CL2 is called as the TDMA informational cluster.
In the initial recording processing of TDMA, at first, message block is recorded among bunch CL2 as TDMA information.Then, a TDMA is recorded in and follows in bunch CL3 of TDMA message block back.
When running out for the whole district of records management information TDMA, and additional information must be recorded in as the ATDMA of the continuity of TDMA and as among bunch CL1 of ATDMA indicator the time content of record TDMA informational cluster.
Figure 17 is the figure of the form of expression TDMA information.
As shown in the figure, TDMA information has the size that is formed for writing down about 2048 bytes of the structure of the information of ATDMA.
In bunch CL2 as the TDMA informational cluster among the TDMA, duplicate record has the TDMA information 32 times of the size of 2048 bytes (=1 Frame).

Light picker 51 comprises: laser diode, photodetector, object lens and optical system, these are not shown in the drawings.Laser diode is the device as the source that is used to produce laser beam.Photodetector is the parts that are used to detect by CD 1 beam reflected.Object lens are the parts as the output terminal of laser beam.Optical system is to be used for coming laser beam radiation to the recording surface of CD 1 and guide the parts of reflecting bundle to photodetector by object lens.
In light picker 51, support object lens as follows by double-shaft mechanism: this mechanism can follow the tracks of and focus direction on mobile object lens.
In addition, can be by the in the radial direction mobile overall optical pick-up 51 of thread mechanism 53 at CD 1.
The drive current as drive signal that produces by laser driver 63 drives the laser diode that is included in the light picker 51 with emission of lasering beam.
The photodetector that adopts in light picker 51 detects the information that is transmitted by CD 1 beam reflected, is directly proportional detected information translation in the electric signal of the light intensity of folded light beam and this electric signal is offered matrix circuit 54.
Matrix circuit 54 has the current/voltage-converted circuit, and it is used for becoming voltage by current conversion of the photodetector output that comprises a plurality of light sensation devices and is used to carry out the matrix processing/amplifying circuit that the matrix that produces essential signal is handled.Essential signal comprises high-frequency signal (perhaps reproducing data-signal) and the focus error signal and the trail-and-error signal of expression reproduction data, and they are used for servocontrol.
In addition, also produce push-pull signal as the signal relevant with the swing of groove.Should the signal relevant be the signal that is used for the swing of detecting groove with the swing of groove.
Should be noted in the discussion above that matrix circuit 54 can physically be integrated in the light picker 51.
Reproduction data-signal by matrix circuit 54 outputs is provided for read/write circuit 55.Also focus error signal and the trail-and-error signal that is produced by matrix circuit 54 is provided for servo circuit 61.The push-pull signal that is produced by matrix circuit 54 is provided for wobble circuit 58.
Read/write circuit 55 is the circuit that are used to carry out following processing, and described processing is such as the Binary Conversion of reproducing data-signal being handled and by adopting the PLL technology to produce to reproduce clock signal to produce the data of being read by light picker 51 etc.The data that produced are applied to modulation/demodulation circuit 56 then.
Modulation/demodulation circuit 56 comprises as the function element of the demoder in the reproduction processes with as the function element of the scrambler in the recording processing.
In reproduction processes, modulation/demodulation circuit 56 is realized as demodulation process decoding processing, that be used for the limited code of run length (run lenght) according to reproducing clock signal.
ECC encoder/decoder 57 is to be used for carrying out the parts that are used for adding error correcting code the ECC encoding process of the data that will be recorded on the CD 1 to and are used to correct the ECC decoding processing of the mistake that is included in the data of reproducing from CD 1.
When reproducing, be stored in the internal storage by modulation/demodulation circuit 56 demodulated data so as to stand that error detection/correction is handled and such as the processing handling of deinterleaving to produce final reproduction data.
According to the order that provides by system controller 60 internally storer read the reproduction data that the result as the decoding processing of being carried out by ECC encoder/decoder 57 obtains and be transferred to the device that is connected to this disk drive.The example that is connected to the device of disk drive is AV (audiovisual) system 120.
As mentioned above, the push-pull signal of the signal that the conduct that processing is exported by matrix circuit 54 in wobble circuit 58 is relevant with the swing state of groove.In wobble circuit 58, the push-pull signal that transmits ADIP information is demodulated to the data stream that comprises the ADIP address.Wobble circuit 58 offers address decoder 59 with this data stream then.
The data that address decoder 59 decoding receives thus to be producing the address, and then this address are offered system controller 60.
Address decoder 59 also handles clocking by using the swinging signal that is provided by wobble circuit 58 to carry out PLL, and this clock signal is offered other parts, for example as encoded clock signal writing time.
As the push-pull signal signal relevant with the swing state of groove, that exported by matrix circuit 54 is the signal that is derived from pre-recorded information PIC.In wobble circuit 58, before being applied in to read/write circuit 55, push-pull signal stands bandpass filtering treatment, and it is carried out binary translation and handles to produce data bit stream.This data bit stream is provided for ECC encoder/decoder 57 then, and described ECC encoder/decoder 57 is used to carry out the ECC decoding and deinterleaves to be handled to extract the data of expression pre-recorded information.The pre-recorded information of being extracted is provided for system controller 60 then.
According to the pre-recorded information of being read, system controller 60 can be carried out the processing such as the processing of multiple processing and copy protection is set.
When record, receive the data that will be recorded from AV system 120.The data that buffering will be recorded in the storer that adopts in ECC encoder/decoder 57.
In this case, 57 pairs of the ECC encoder/decoders buffered data that will be recorded is carried out and is handled.This processing comprises the processing of the processing, interleaving treatment and the increase subcode that add error correcting code.
Before being provided for read/write circuit 55, the data of finishing the ECC encoding process are subjected to the demodulation process in modulation/demodulation circuit 56, such as the demodulation of adopting RLL (1-7) PP method.
In these encoding process of carrying out when record, the clock signal that produces from above-mentioned swinging signal is used as encoded clock signal, and it is as the reference signal.
After finishing these encoding process, the data that are recorded are provided for read/write circuit 55 so that stand to write down compensation deals, such as the fine setting of recording power to produce adjustment for the shape of the performance number of the bests of factors such as some shape that comprises recording layer characteristic, laser beam and line speed record and Laser Driven pulse.After finishing the record compensation deals, the data that be recorded are provided for laser driver 63 as the Laser Driven pulse.
Laser driver 63 transmits the Laser Driven pulse and produces laser beam to drive from diode for the laser diode that is applied in the light picker 51.By this way, in CD 1, produce the groove (pit) that is applicable to record data.
Should be noted in the discussion above that laser driver 63 comprises is used for by the monitoring laser output power laser output being controlled to be and environmental baseline, for example so-called APC (automated power control) circuit of the irrelevant fixed value of environment temperature.Detecting device is arranged in the light picker 51 with the watch-dog as the monitoring laser output power.System controller 60 provides each the desired value of laser output power that is used to write down with reproduction processes.The order of magnitude of laser output is controlled as and is used to write down or the desired value of reproduction processes.
Servo circuit 61 produces multiple servo drive signal to carry out servo processing from focus error signal and trail-and-error signal, wherein receives described focus error signal and trail-and-error signal from matrix circuit 54.Servo drive signal comprises focusing, tracking and thread servo drive signal.
Particularly, respectively according to the focusing that drives the double-shaft mechanism that in light picker 51, adopts respectively and the focus error signal and the trail-and-error signal of tracking coil, produce and focus on and follow the tracks of drive signal.Thereby tracking and focus servo loop are created as the loop that comprises light picker 51, matrix circuit 54, servo circuit 61 and double-shaft mechanism.
In addition, according to the track jump command that receives from system controller 60, servo circuit 61 turn-offs tracking servo loop and carries out the track jump by output jump drive signal and handle.
On this, according to thread rub-out signal and the visit operation control signal that receives from system controller 60, servo circuit 61 produces the thread drive signals, with drive thread mechanism 53.Obtain the low-frequency component of thread rub-out signal as the trail-and-error signal.Thread mechanism 53 has the mechanism that comprises transmission gear, thread motor and be used to keep the main shaft of light picker 51.According to the line drive signal, thread mechanism 53 drive thread motors are with the required distance of slip light picker 51.Should be noted in the discussion above that mechanism itself does not illustrate in the drawings.
Spindle servo circuit 62 control spindle motors 52 rotate with CLV.
Spindle servo circuit 62 obtains the clock signal of generation in PLL handles, be used for swinging signal, and more current rotational speed and predetermined CLV reference velocity are to produce spindle error signal as the information of the current rotational speed of relevant spindle motor 52.
In addition, the reproduction clock signal that produces when the data reproduction by the PLL circuit that is applied in the read/write circuit 55 is used as the reference clock signal of decoding processing, and the information of the current rotational speed of relevant spindle motor 52.Thus, by comprising this reproduction clock signal, can produce spindle error signal with predetermined CLV reference velocity.
Then, the main shaft drives signal that spindle servo circuit 62 outputs produce according to spindle error signal is to carry out the CLV rotation of spindle motor 62.
And, spindle servo circuit 62 also according to the main shaft startups/brake control signal that receives from system controller 60 produce the main shaft drives signal with execution start, stop, the processing of acceleration and deceleration spindle motor 52.
Control the multiple processing that realizes by aforesaid servo-drive system and recording/reproducing system by system control sytsem 60 according to microcomputer.
According to the order that receives from AV system 120, system controller 60 is carried out multiple processing.
For example, when receiving write command (perhaps write data order) from AV system 120, system controller 60 at first moves to the address that data will be written into light picker 51.Then, 56 pairs of data that receive from AV system 120 of ECC encoder/decoder 57 and modulation/demodulation circuit are carried out above-mentioned encoding process.The example of data is video and the voice datas that produce according to the several different methods such as MPEG2.Subsequently, as mentioned above, for physical record data on CD 1, read/write circuit 55 provides the Laser Driven pulse of expression data for laser driver 63.
On the other hand, for example, when receiving from AV system 120 when CD 1 is read the read command of the data such as MPEG2, system controller 60 is at first carried out to search and is handled, arrive destination address with mobile light picker 51, will be in this destination address from CD 1 sense data.That is to say that system controller 60 drives light picker 51 so that the destination address of visit appointment in seek command for servo circuit 61 output seek command.
Thereafter, necessity control of operation processing is arrived AV system 120 with the data transmission with specified portions.That is to say, from CD 1 sense data, in read/write circuit 55, modulation/demodulation circuit and ECC encoder/decoder 57, carry out the processing such as decoding and buffering processing, and the data transmission of being asked is arrived AV system 120.
Should be noted that, data recording is being reproduced the processing of data in CD 1 and from CD 1, and system controller 60 can be controlled to the visit of CD 1 and by the recoding/reproduction that uses the ADIP address of being detected by wobble circuit 58 and address decoder 59 and handle.
In addition, BCA be present on the CD 1 and the prerecorded information (PIC) on the CD 1 of being recorded in as only coming under the situation of reproducing the wobble of distinguishing, on the predetermined point of time when for example CD 1 is placed on the disk drive, system controller 60 is read unique ID from the BCA on the CD 1.
In this case, carry out with the predetermined data field PR of the target that is set to search processing and BCA and search the control of handling.That is to say, give an order with the most inboard circumference for servo circuit 61 by use light picker 51 visit CDs 1.
After a while, driving light picker 51 follows the tracks of to obtain the push-pull signal as the information that is transmitted by folded light beam to carry out to reproduce.Then, in wobble circuit 58, read/write circuit 55 and ECC encoder/decoder 57, carry out decoding processing, to produce as pre-recorded information and the BCA information of reproducing data.
According to BCA information and pre-recorded information, read these information from CD 1 as mentioned above, system controller 60 is carried out the processing such as processing that laser power is set and copy protection processing.
In structure shown in Figure 180, in system controller 60, adopt cache memory 60a.Use cache memory 60a to be used for maintenance information, for example TDDS, TDFL and/or SRRI read these information from the TDMA that is recorded on the CD 1, and the result need not visit CD 1 also can upgrade these information.
When the CD 1 that does not also have finalization was placed on the disk drive, for example, the parts of system controller 60 console panel drivers were read TDDS, TDFL and/or SRRI with the TDMA on being recorded in CD 1 and they are stored in the cache memory 60a.
After a while, when carrying out the replacement address process or owing to detected defective, update stored in SRRI and/or TDFL among the cache memory 60a with renewal and/or write data.
For example, the each execution replaced address process to write or new data and when upgrading SRRI and TDFL more in CD 1, can incrementally list the TDMS updating block in TDMA on being recorded in CD 1 or ATDMA in.Yet these are done, and the TDMA that is recorded on the CD 1 will run out in the time more early.
In order to address this problem, take a kind of method, thus, for example, when the LRA (Ji Lu address at last) that upgrades after the record data incrementally as the address of SRRI, update stored in the SRRI among the cache memory 60a, up to a certain number of times, and certain time point after that, by listing the TDMS updating block in the SRRI that is stored in the renewal among the cache memory 60a is recorded on the CD 1.
In addition, also there is the method that to expect, thus, the SRRI that is stored among the cache memory 60a is upgraded required number of times, usually up to ejecting CD 1 from disk drive, and, for example, be stored in up-to-date SRRI among the cache memory 60a and/or TDFL and be transmitted to TDMA on the CD 1 when when disk drive ejects CD 1.
By the way, the general structure of disk drive shown in Figure 180 is the structure that is connected to the disk drive of AV system 120.Yet disk drive provided by the invention can be connected on the device such as personal computer.
In addition, disk drive can be designed to be connected to the structure of device.In this case, different with structure shown in Figure 180, this disk drive comprises operating unit and display unit or the interface component that is used for the input and output data.That is to say, according to the operation of carrying out by the user data recording is reproduced data to dish and from CD 1, and need terminal as the terminal that is used for the input and output data.
Certainly, other typical structure is possible.For example, disk drive can be designed to a pen recorder or transcriber only.
5: the data recording/reproducing of not replacing the district is handled
5-1: data are write first example of processing
By with reference to process flow diagram shown in Figure 19, the following describes and explained the processing of in the processing of data recording to the CD 1, carrying out by the system controller 60 that in disk drive, adopts, described CD 1 is formatted not comprise the replacement district shown in Fig. 1 (b).
Should be noted in the discussion above that when the data of carrying out explained later and write when handling that CD 1 has been placed on the disk drive, and TDDS, TDFL and SRRI are sent to cache memory 60a from the TDMA that is placed on the CD 1 on the disk drive.
In addition, when from host apparatus, for example AV system 120 receives when writing the request of handling or reading to handle, and is the destination address of logical sector address (perhaps LSN) in that the request middle finger is tailor-made.Disk drive actuating logic/physical address translations is handled, logical sector address is changed into physical sector address (perhaps PSN).
Should be noted in the discussion above that the physical address of first sector in the user data area that is necessary to be recorded among the TDDS adds in the logical sector address in order to change into physical sector address by the logical sector address of main frame appointment.
Data with bunch unit record in CD 1.
Suppose by system controller 60 and receive the request that writes data into address N (perhaps logical sector address N, wherein N is 32 multiple) from the host apparatus such as AV system 120.
In this case, system controller 60 beginnings are by the processing of flowcharting shown in Figure 19.At first, at step F 101 and F102, with reference to the SRRI that is stored in SRRI among the cache memory 60a or recent renewal in cache memory 60a so as to be created in assigned address bunch in definite result of record data whether.
That is to say that in the processing that step F 101 is carried out, the SRR clauses and subclauses among the check SRRI are to find the SRRI clauses and subclauses of the SRR that comprises assigned address.
Particularly, at first, change into physical sector address N ' by the logical sector address N of host apparatus appointment.Then, physical sector address N ' and the address that is recorded in each SRR clauses and subclauses are checked in detail, to obtain to distribute to the SRR numbering that has corresponding to the SRR clauses and subclauses of the recording address of physical sector address N '.
Then, in the processing that next step F102 carries out, whether be used for writing the address and by the LRA of the SRR of the number-mark of distributing to the SRR clauses and subclauses that is obtained relatively of the request appointment of processing, be definite result of the address of having write down so that produce in the processing that next step F103 carries out about the address of the request appointment that is used for writing processing.That is to say, in the request LRA of the SRR of the address of appointment and SRR clauses and subclauses relatively, to produce about physical sector address N ' whether less than definite result of the NWA of SRR.Indicate the NWA of physical sector address N ' if determine the result, so the physical sector address N ' address that is confirmed as having write down less than SRR.As previously described, the NWA of SRR can obtain from the LRA of the SRR that described by the SRR clauses and subclauses.
Indicate physical sector address N ' to equal the NWA of SRR if determine the result, physical sector address N ' is confirmed as not being the address of having write down so.Because the NWA of SRR is appendix measuring point (postscript-recordingpoint), in this case, the flow process of processing proceeds to step F 104 from step F 103, and in this step F 104, data are written into physical sector address N '.
That is to say that in this case, the address of carrying out appointment in the write order that data write processing is not the address of having write down.Therefore, normally carry out data and write processing.Yet, if owing to the damage that causes on the CD 1 is caused or other reason causes makes a mistake in data are write, can alternatively carry out the replacement address process.
At first, in the processing that step F 104 is carried out, system controller 60 is carried out the control that writes data on the CD 1.Particularly, system controller 60 move pick-up 51 to the address of appointment with the data recording of visiting this address and will will be written into according to data write request in this address to CD 1.
Write processing if normally finish data, handle to proceed to step F 105, in this step F 105, update stored in SRRI among the cache memory 60a with the appendix record of reflection record data in the SRR from step F 104.Then, if necessary, just, upgrade the opportunity that is recorded in the SRRI on the CD 1, so also upgrade the SRRI of record on the CD 1 if exist.That is to say, the TDMS updating block is recorded on the CD 1.
At last, end up being write request and the processing carried out.
Should be noted in the discussion above that if the physical sector address N ' of appointment is sent to the device that sends write request with illegal parameter error so greater than the NWA of SRR in the write request.Yet the process flow diagram shown in Figure 19 is not represented the situation of the physical sector address N ' of appointment in the write request greater than the NWA of SRR.
If the address that appointment in the request of processing is write in the definite result's indication that produces in the processing of carrying out in step F 103 is the address of having write down, the data that will be written on the CD 1 according to data write request can not be written in the address of appointment so.In this case, the flow process of processing proceeds to step F 106.
At first, in the processing that step F 106 is carried out, check that the TDMA that comprises ATDMA is to produce the definite result who whether has used up about the TDMA (and ATDMA) that is used for recorded information.If in comprising the TDMA of ATDMA, there is not effective and idle district, can not carry out the replacement address process more so.In this case, the flow process of processing proceeds to step F 107, and in this step F 107, for response request, error message is transferred to the device that sends data write request.
On the other hand, if in comprising the TDMA of ATDMA, still there is effective and idle district, in step F 108 and step subsequently, carry out the processing that updates stored in the data in the CD 1.
At first, in the processing that step F 108 is carried out, check SRR is to produce about NWA whether be present in definite result among the SRR.Checked SSR is the SRR that finds in the processing that step F 101 is carried out, and just, comprises the SRR that replaces the target source address.As mentioned above, the SRR that does not comprise NWA is the SRR that closes (close).That is to say, check that SRR is to produce the definite result who whether is still the SRR that opens (open) about target SRR.Determine the result by producing this with reference to the information of in the SRRI header, describing.
Open SRR if definite indicating target SRR as a result is still, the flow process of Chu Liing proceeds to step F 109 so, and in this step F 109, the data that will be written to CD 1 according to data write request are written in the district of the NWA that originates in SRR.
Then, the flow process of processing proceeds to step F 111, carries out necessary renewal in this step and handles.
That is to say,, need execution to replace address process for upgrading to handle so because the processing that data are write on the CD 1 is to upgrade the processing that records the data on the CD 1.Thus, must on TDFL, produce new DOW clauses and subclauses and list in.New DOW clauses and subclauses comprise physical sector address N ' and NWA, physical sector address N ' is directly appointment in the data write request, target source address as an alternative, because physical sector address N ' is the address of having write down, NWA has been used as the target of the data recording and processing of step F 109 execution, goal displacement address as an alternative.
In addition, because the data that will be written on the CD 1 according to data write request are written into SRR, so also must upgrade the SRR clauses and subclauses of SRR.
And, owing to upgraded TDFL and SRRI, need to upgrade TDDS.
Thus, in the processing that step F 111 is carried out, at first update stored in TDFL, SRRI and TDDS among the cache memory 60a.Then, according to the renewal of TDFL, SRRI and TDDS, produce and incrementally write down the TDMS updating block among the TDMA on CD 1 (perhaps ATDMA).
On the other hand, if the definite SRR of indicating target as a result that produces in step F 108 is the SRR that has closed, the flow process of processing proceeds to step F 110.The data that will be written to CD 1 then according to data write request are written in one the district of the maximum among the NWA that originates in the SRR that opens.That is to say that the data that will be written to CD 1 according to data write request are written to and originate in the district that opens the NWA among the SRR last that is present in the user data area.By last SRR, comprise and be present in the SRR that opens the maximum address among the SRR.
When finishing data recording and processing, the flow process of processing proceeds to step F 111, in this step F 111, carries out with above-mentioned identical renewal and handles.Particularly, at first, update stored in TDFL, SRRI and TDDS among the cache memory 60a.Then, according to the renewal of TDFL, SRRI and TDDS, produce and incrementally write down the TDMS updating block among the TDMA on CD 1 (perhaps ATDMA).
As mentioned above, the flowcharting shown in Figure 19 is in order to be the request of processing of address of the address of having write down and the performed replacement address process of new data more just at the right time in response to data are write.Yet, should be noted in the discussion above that in response to data are write be just at the right time the address in the defect area the address processing request and new data more also can be carried out the replacement address process in the same way.
For example, suppose, though in the request of the processing that data is write CD 1 specified address be not recorded bunch in the address, described be not recorded bunch be do not have data recording therein bunch, this bunch made and can not correctly data be write wherein by defective.In this case, the flow process of processing proceeds to step F 106 to carry out identical replacement address process in step F 106 with step subsequently from step F 103.
Yet, in the situation of the replacement address process performed, by upgrading TDFL by the new DFL clauses and subclauses of TDMS updating block establishment that incrementally write down in the mode identical with the DOW clauses and subclauses for this defect cluster.
5-2: data are write second example of processing
By the way, in the processing that the step F 109 of process flow diagram shown in Figure 19 is carried out, carry out to relate to and comprise that data write the replacement address process in the district among the SRR of address specified in the processing.Usually, this replacement address process can not brought problem.In fact, replace address process and can have such advantage: the position of physically approaching to replace the target source position can be elected as and replace the goal displacement position.Following benefit has been brought in this replacement goal displacement position: can shorten from replacing the search distance with aftertreatment of goal displacement position sense data.Yet for some application of carrying out in the host apparatus such as AV system 120, in some cases, problem may be brought in the replacement goal displacement position among the SRR identical with replacing the goal displacement position.
At first, this problem interpretation is as follows.
Figure 20 represents to open SRR#1 and SRR#2 respectively and is chosen in NWA among the SRR identical with replacing the goal displacement address to avoid defective and to upgrade the processing of the data that write down.
Especially, Figure 20 (a) expression is as the dash area among the SRR#1 of the defective in this SRR.Suppose, become NWA in certain time point address AD 0, and host apparatus send with data Dta be written to address AD 0 place bunch in the request of processing.In this case, because what originate in address AD 0 bunch is defect cluster, replace address process so carry out.That is to say that the data DTa that will be written to this defect cluster must be present in bunch scope among the SRR#1, as bunch scope that originates in address AD 1 as shown in the figure by actual being written to.In this case, be present among the SRR#1, be called as the replacement goal displacement district that replaces address process as bunch scope that originates in bunch scope of address AD 1.
After data DTa was written to aforesaid bunch of scope, NWA was displaced to address AD 2.Therefore, renewal is as the LRA LRA (Ji Lu address at last), that write down in the SRR of SRR#1 clauses and subclauses of SRR#1.
Disk drive upgrades aforesaid SRRI.Yet in this case, some application that move in host apparatus may not need up-to-date NWA.Therefore, this application can send write order and not NWA be updated to address AD 2.In addition, just waiting for the order of carrying out on will the command queue in disk drive at the write order of assigned address AD1, NWA is updated and can not cancels this write order.In this case, data can be written in the district that originates in address AD 1.
For example, suppose shown in Figure 20 (b) that after data DTa, other data DTb is written on the CD 1.Suppose irrelevantly current NWA be with NWA from the address AD consistent 0 displacement with previous NWA corresponding to the distance of the size of data DTa the result of arrival address AD1, this moment write data DTa same application send write order with other data DTb is written to originate in address AD 1 bunch.In this case, disk drive is carried out the processing by flowcharting shown in Figure 19.Yet, since data DTa by actual be written to originate in address AD 1 bunch, write processing so carry out the data of handling as Data Update.Therefore, data DTb be written to originate in address AD 2 bunch, it is actual NWA.After Data Update is handled, once more NWA is updated to address AD 3 and produces new DOW clauses and subclauses.
Yet still in this case, the application of carrying out in host apparatus does not need up-to-date NWA.Therefore, suppose irrelevantly once more current NWA be with NWA from the address AD consistent 1 displacement with previous NWA corresponding to the distance of the size of data DTb the result of arrival address AD2, identical application this moment send write order with other data are written to originate in address AD 2 bunch in.Therefore, in next request of data, specify address AD 2.
Still in this case, disk drive is carried out the data of handling as Data Update and is write processing, and it need replace address process.In this replaces address process, other data be written to originate in address AD 3 bunch, it is actual NWA, and after this Data Update is handled, produces new DOW.
That is to say that before sending the order that writes data among the SRR identical with the data that before write, some application may not need up-to-date NWA.When this application is sent when carrying out data and writing the data write order of the request of processing, disk drive is actual carries out the Data Update processing that the data that replace being asked are write processing, has consumed the district of the DOW clauses and subclauses that are used to write down new generation in vain.
By with reference to figure 21A, 21B and 22, following interpretation consider that the data of said circumstances write processing.
Figure 22 illustrates processing is write in expression by the data of system controller 60 execution process flow diagram.Yet, because step F 101 to F107 is identical with the step of the process flow diagram shown in Figure 19, so the description of these steps no longer repeats.
Writing by the data of flowcharting shown in Figure 22 in the situation of processing, if the address of appointment is the address of having write down and has the free area in TDMA or ATDMA in the data write request, in order to carry out the replacement address process, the flow process of processing proceeds to step F 108A.In this step, check SRR is to produce about NWA whether be included in definite result among the SRR that is different from the SRR that comprises address specified in the data write request.
Should be noted in the discussion above that at least 2 SRR are in open mode usually.Therefore, the definite result who produces in the processing that step F 108A carries out does not almost negate.Yet, be the single SRR that is in open mode if be included in the SRR of the address of appointment in the data write request, the definite result who produces in the processing that step F 108A carries out is negative so.In this case, the flow process of processing proceeds to step F 107, and in this step, the data of being represented by this flow process are write before the end of run of processing, send error message to the application of sending data write request.
On the other hand, if determine that results verification NWA is included among the SRR that is different from the SRR that comprises address specified in the data write request, the flow process of handling proceeds to step F 109A, and in this step, the data of wanting in data write request are written to other SRR in the district that originates in NWA.That is to say, carry out the replacement address process of using the district among other SRR and be used as the Data Update processing.Then, at next step F111, upgrade TDFL and TDDS according to replacing address process.Thereafter, renewal is used for the SRRI of the content of the SRR of goal displacement SRR as an alternative too.
For data write request, to write in the processing by the data of flowcharting shown in Figure 22, the address of appointment is the address of having write down in the data write request, and carries out thus and replace address process to upgrade the data that have been recorded on this address.Should be noted in the discussion above that because the address of appointment is address in the defect area in the data write request, so can also carry out the replacement address process in the same way.For example, suppose that promptly being used in the address that data are write appointment in the request of the processing on the CD 1 is address in Unrecorded bunch, this bunch made and can not correctly data be write wherein by defective.In this case, the flow process of processing continues from step F 103 to step F 106, carries out identical replacement address process in the goal displacement district as an alternative with the district among other SRR of use in step F 106 and step subsequently.
Figure 21 is illustrated respectively in above-mentioned data to write the figure that the data of carrying out in the processing are write the state of processing.The spitting image of Figure 20, each is the SRR that opens for SRR#1 and SRR#2.
In Figure 21 A, suppose in the dash area of SRR#1, to detect defect cluster and will be written to the data DTa of this defect cluster thereby be subjected to the replacement address process.If select the NWA of another SRR in replacement address process shown in Figure 22, then shown in Figure 21 A, data DTa will be written to for example address AD 11, and it is the NWA as the SRR#2 of another SRR.Therefore, in replacing address process, data DTa is stored in bunch scope that starts from address AD 11, and the NWA of SRR#2 is updated to address AD 12.That is, upgrade the LRA be recorded in as in the SRR clauses and subclauses of the SRR#2 of the LRA of SRR#2.
On the other hand, in this case, this uses supposition correctly, and the NWA among the SRR#1 also is not updated.If the request of the processing that does not need to obtain up-to-date NWA to the data DTb after the DTa being write on the CD 1 is sent in this application, this uses assigned address AD1, and it is assumed that the up-to-date NWA of SRR#1.Therefore, data DTb normally is written in the district that originates in AD1, and the NWA of SRR#1 is updated to address AD 2.
That is to say that this application does not suppose mistakenly that NWA has by the situation of front by the example explained with reference to Figure 20.Therefore, can solve the problem that generation caused by unessential DOW clauses and subclauses.
Should be noted in the discussion above that in this case under situation about not known by this application, the NWA of SRR#2 can be updated.If carry out the replacement address process by data being write among the SRR that is different from as the SRR of the source target of data write request, in essence, the information about target SRR is correctly inferred in this application in advance.This is not influence the correct deduction of being carried out by this application because upgrade the processing of the NWA of other SRR#2, and this infers the deduction of conduct about the information of target SRR#1.
5-3: data are read to handle
Below, by the process flow diagram shown in reference Figure 23, describe below and explained by the processing of system controller 60 execution to reproduce data from the CD 1 that is placed on the disk drive.
Suppose that system controller 60 receives the request from the processing of an address read-outing data from the host apparatus such as AV system 120, wherein be this address of logical sector address N in that this request middle finger is tailor-made.
In this request, the processing that system controller 60 starts by flowcharting shown in Figure 23.
As shown in the figure, process flow diagram starts from step F 201, in this step, whether system controller 60 is definite result of the address of having write down with reference to the SRRI of the SRR that is included in logical sector address N specified in the request so that produce in the processing that next step F202 carries out about the address of appointment.Particularly, at first, be converted into physical sector address N ' by the logical sector address N of host apparatus appointment.By will be recorded among the TDDS, as the initial physical sector address and the logical sector address N addition of the initial physical sector address of user data area, can in address translation, find physical sector address N '.Then, from physical sector address N ', obtain the SRR numbering and by the SRR clauses and subclauses of this number-mark.The SRR clauses and subclauses indicate whether write down data on physical sector address N '.
If do not have record data on the address of appointment, then the flow process of Chu Liing proceeds to step F 203 from step F 202, and in step F 203, sending error message to host apparatus is misaddress with the specified address of notice host apparatus.
On the other hand, if data have been write down in the address in appointment, then the flow process of Chu Liing proceeds to step F 204 from step F 202, in step F 204, search comprises whether the DOW or the DFL clauses and subclauses of the specified address of target source address are the definite results who has finished definite result of the address of replacing address process so that produce conduct in the processing that next step F205 carries out about specified address as an alternative in TDFL.
If it is not to finish the address of replacing address process that the definite result who produces in the processing that next step F205 carries out indicates specified address, this is by comprising that by not existing the DOW of the physical sector address N ' of target source address and the fact of DFL clauses and subclauses confirm as an alternative, then the flow process of Chu Liing proceeds to step F 206 from step F 205, in step F 206, from specified address read-outing data, and be sent to host apparatus such as AV system 120.Then, finish the execution of the processing represented by this flow process.
Therefore, in normal reproduction is handled, from the user data area sense data.
On the other hand, if it is to finish the address of replacing address process that the definite result who produces in the processing that next step F205 carries out indicates specified address, this is by comprising that by DOW and DFL clauses and subclauses the fact of the physical sector address N ' of target source address confirms as an alternative, then the flow process of Chu Liing proceeds to step F 207 from step F 205, in step F 207, replacement goal displacement address read-outing data from be included in DOW or DFL clauses and subclauses, and be sent to host apparatus such as AV system 120.Then, finish the carrying out of the processing represented by this flow process.
Therefore, even after data are updated, send in the situation of conduct to the data read request of the request of the reproduction of institute's data updated,, can correctly reproduce up-to-date data and be sent to host apparatus by carrying out above-mentioned processing.
5-4:ATDMA detects processing
By the flow process shown in reference Figure 24, the following describes and be explained as follows processing, described processing is carried out to check existing of ATDMA when the CD 1 with form shown in Figure 16 is placed on the disk drive by system controller 60.
Suppose have as shown in figure 16, comprise ATDMA and do not comprise that the CD 1 of the form of replacing the district has been placed on the disk drive.
Process flow diagram shown in Figure 24 starts from step F 301, in this step, the CD 1 that system controller 60 is placed from disk drive reproduces the TDMA indicator that is included in the TDMA the form shown in Figure 16, so that produce the definite result who whether comprises the ATDMA indicator about bunch CL1 in the processing that next step F302 carries out.
If bunch CL1 does not comprise the ATDMA indicator, then the flow process of Chu Liing proceeds to step F 303 from step F 302, in step F 303, in order to read TDMA information about the information of the ATDMA of CD 1 from a bunch CL2 from the TDMA information acquisition.Information about ATDMA is reference position and the size of ATDMA.Then, at next step F304, obtain up-to-date TDMS from TDMA.
That is to say that bunch CL1 that does not comprise the ATDMA indicator also indicates up-to-date TDMS to be present among the TDMA and do not have data to be recorded among the ATDMA.Therefore, read up-to-date TDMS from TDMA.TDDS, the SRRI and the TDFL that obtain from up-to-date TDMS are sent to cache memory 60a, make to read TDDS, SRRI and TDFL from cache memory 60a in subsequently record and reproduction processes.
Should be noted in the discussion above that data recording/reproducing device may not read TDMA information from a bunch CL2.In this case, can not discern the existence of ATDMA.Yet the reference position of ATDMA has the value greater than the value that is recorded in the last logical address among the TDDS, as the last logical address (the perhaps last LSN of user data area) of user data area.And, logical address and do not have variation corresponding to the relation between the physical address of logical address, and do not carry out from this part sense data and data are write the processing of this part.Therefore, kept the compatibility of recoding/reproduction.
CD 1 can be placed on the data recording/reproducing device that can not discern ATDMA.In this case, when TDMA had been updated to its end, data recording/reproducing device can not upgrade TDMA again and may carry out the processing of closing CD 1 thus, that is to say, stops the processing of further writing processing.
On the other hand, if the definite result who produces in the processing that step F 302 is carried out indicates the ATDMA indicator to be recorded among bunch CL1, then the flow process of Chu Liing proceeds to step F 305, and in this step, system controller 60 identifies the center of ATDMA indicator bunch.
Then, the flow process of processing proceeds to step F 306, and in this step, system controller 60 produces the definite result who whether exists about ATDMA.Indicate ATDMA to exist if determine the result, the flow process of Chu Liing proceeds to step F 309 so, in this step, obtains the size of the TDMA among the OSA (outer spare area) or the size of OSA, to obtain the size of ATDMA.Before explaining TDMA information shown in Figure 17, the size of the TDMA among the OSA and the size of OSA have been mentioned.Find the start address of ATDMA then from LAA (the last ADIP address of data field).From ATDMA obtain up-to-date TDMS thereafter.
That is to say that the up-to-date TDMS of ATDMA indicator indication that is recorded among bunch CL1 is present among the ATDMA, so that can obtain up-to-date TDMS from ATDMA.TDDS, the SRRI and the TDFL that obtain from up-to-date TDMS are transmitted to cache memory 60a, so that can read TDDS, SRRI and TDFL from cache memory 60a in subsequently record and reproduction processes.
Should be noted in the discussion above that value that some data recording/reproducing devices can the ATDMA indicator of detection record in bunch CL1 and the parameter between the up-to-date TDMS do not match, and therefore can stop data to write processing.Yet, even in the situation of this data recording/reproducing device, also kept the compatibility of minimum recoding/reproduction.
If the definite result who produces in the processing that step F 306 is carried out indicates ATDMA to exist, as ATDMA indicator among bunch CL1 confirmed by being recorded in, but the size of ATDMA is not set also, if and all information also have been recorded among the DMA, the flow process of handling proceeds to step F 307, in this step, the whole district of the TDMA on the CD 1 is confirmed as being used for recorded information fully.That is to say, determine that CD 1 finished finalization processing.Given this, in the processing that next step F308 carries out, obtain to comprise the up-to-date DMS of DDS, SRRI and DFL and to send cache memory 60a to from DMA, so that can in subsequently record and reproduction processes, read DDS, SRRI and DFL from cache memory 60a.
6: comprise the data recording/reproducing processing of replacing the district
6-1: data are write first example of processing
Below, by with reference to process flow diagram shown in Figure 25, the following describes the data of having explained by the embodiment execution that is used to have the CD 1 that comprises the form of replacing the district shown in Fig. 1 (a) and write processing.
Should be noted that, still in this case, write the time point of processing will carrying out following data, CD 1 has been placed on the disk drive, and from the TDMA that is recorded on the CD 1 TDDS, TDFL and SRRI is copied to cache memory 60a.
And, when disk drive receives data write request and/or data when reading to ask clearly from the host apparatus such as AV system 120, before data are write and/or are read to handle disk drive will as data write and/or the address of the target reading to handle, logical sector address (LSN) specified in request changes into physical sector address (PSN), and with have aforesaid CD 1 same way as that does not comprise the form of replacing the district and in bunch unit, carry out data and write and/or read processing.
Suppose that the system controller 60 that adopts receives from the host apparatus such as AV system 120 and specify the data write request address, address N (perhaps logical sector address N, wherein N is 32 multiple) of writing the target of processing as data in disk drive.
In this case, system controller 60 opens the beginning and writes processing by the data of flowcharting shown in Figure 25.As shown in the figure, process flow diagram starts from step F 401, in this step, reads the SRRI of recent renewal from cache memory 60a.Then, in the processing that next step F402 carries out, check that SRRI is the address of having write down or definite result of Unrecorded address to produce about specified address, that is to say, place, specified address bunch in whether write down data.The address of having write down is the address of record data on it, and Unrecorded address is the address that does not also have record data on it.
That is to say, in the processing that step F 401 is carried out, search comprises the SRR clauses and subclauses of the SRR of assigned address in SRRI, and in the processing that next step F402 carries out, the result of search is used to produce the definite result who whether has the SRR clauses and subclauses of the SRR that comprises assigned address about SRRI.
Particularly, at first, in the processing that step F 401 is carried out, be converted into physical sector address N ' by the logical sector address N of host apparatus appointment.Then, the address of describing in physical sector address N ' and the SRR clauses and subclauses is compared, with obtain SRR number and by this number sign, as SRR clauses and subclauses corresponding to the SRR clauses and subclauses of physical sector address N '.
Then, in the processing that next step F402 carries out, corresponding to the physical sector address N ' of the logical sector address N of appointment in the data write request and be included in the SRR clauses and subclauses that obtained, corresponding SRR LRA relatively.Data whether have been write down on the physical sector address N ' of the logical sector address N of SRR clauses and subclauses indication appointment in corresponding to data write request.That is to say, write down data on the physical sector address N ' less than the logical sector address N of physical sector address N ' indication appointment in of the NWA of SRR corresponding to data write request.Can find NWA among the LRA from be recorded in the SRR clauses and subclauses.
If the physical sector address N ' corresponding to the logical sector address N of appointment in the data write request equals to indicate the NWA of appendix measuring point, then physical sector address N ' indication does not also have record data on physical sector address N '.In this case, to proceeding to step F 404, in step F 404, data are written to physical sector address N ' to the flow process of processing from step F 403.
That is to say that in this case, to write the address of appointment in the write order of processing be not the address of having write down carrying out data.Therefore, normally carry out data and write processing.Yet,, can carry out the replacement address process so on the contrary if produce mistake in the processing owing to the damage on the CD 1 or other reason cause writing in data.
At first, in the processing that step F 404 is carried out, the control that system controller 60 is carried out on the assigned address that writes data into CD 1.Particularly, system controller 60 moves to specified address to visit this address and record data with pick-up 51, and in this address, these data are written on the CD 1.
Write processing if normally finish data, handle to proceed to step F 405,, be stored in SRRI among the cache memory 60a and be updated with reflection data appendix is recorded among the SRR in this step from step F 404.Then, if desired, that is to say, upgrade the chance that is recorded in the SRRI on the CD 1, so also upgrade the SRRI that is recorded on the CD 1 if exist.That is to say that the TDMS updating block is recorded on the CD 1.
At last, end up being the performed processing of write request.
Should be noted in the discussion above that if the physical sector address N ' of appointment transmits illegal parameter error to the device that sends write request so greater than the NWA of SRR in the write request.Yet process flow diagram shown in Figure 25 does not illustrate the situation of the physical sector address N ' of appointment in the write request greater than the NWA of SRR.
If specified address was the address of having write down during the definite result who produces in the processing that step F 403 is carried out indicated the request of writing processing, the data that will be written to CD 1 so according to data write request can not be written to specified address.In this case, the flow process of processing proceeds to step F 406.
At first, in the processing that step F 406 is carried out, check that the TDMA that comprises ATDMA is to produce the definite result who whether all has been used for recorded information about TDMA (and ATDMA).If the replacement address process can not be carried out so again in effectively not more and free area at the TDMA that comprises ATDMA.In this case, the flow process of processing proceeds to step F 407, in this step, sends error message in response to this request to the device that sends data write request.
On the other hand, if in comprising the TDMA of ATDMA, still exist effectively and the free area, then the flow process of Chu Liing proceeds to step F 408, in this step, produce about whether there being the definite result who replaces the district, that is, as the enough big enough free areas that are included in ISA or OSA that are used for carrying out the district that replaces address process.
Can produce this definite result by reference current effective TDDS.As the front by with reference to as described in the figure 8,4 bytes at byte location 1216 to 1219 places of TDDS are used to be recorded in the address of next available sector among the ISA, and 4 bytes at byte location 1220 to 1223 places of TDDS are used to be recorded in the address of next available sector among the OSA.From the address of being write down, can determine the state of the available area among ISA and the OSA.As an alternative, the spare area all mark that can also write down with reference to byte location 52 places at TDDS is to produce this definite result.By as described in DDS shown in Figure 4, use the spare area all mark to be used up fully as the front with indication ISA and OSA.That is to say, replace the time point that the district runs out, the spare area all mark is set at all.
If the definite result who in the processing that step F 408 is carried out, produces indicate exist be included among ISA or the OSA, as the enough free areas that are used to carry out the enough big district that replaces address process, the flow process of Chu Liing proceeds to step F 409 so.
In this case, adopt to originate in as an alternative the ISA in goal displacement district or the district of the next record address among the OSA, replace address process, can write down according to data write request and will be written to data on the CD 1 by carrying out.
The flow process of Chu Liing proceeds to step F 410 then, in this step, carries out necessary renewal and handles.
That is to say, write processing owing to carried out the data of handling as Data Update, therefore by carrying out aforesaid replacement address process, record will be written to the data of CD 1 according to data write request.Therefore, must in TDFL, list new DOW clauses and subclauses in.Particularly, be necessary to produce describe target source address as an alternative, corresponding to the physical sector address N ' of the logical sector address of appointment in the data write request and as an alternative the goal displacement address, comprise that data that the conduct among ISA or the OSA is carried out in step F 409 write the DOW clauses and subclauses of address in district in the realistic objective district of processing.Therefore, the physical sector address N ' that serves as the replacement target source address of DOW clauses and subclauses is the address of having write down previous data on it.
As mentioned above, by upgrading described TDFL in the above-listed DOW of the making new advances clauses and subclauses of TDFL.And, owing to upgraded TDFL, so TDDS also has been updated.
That is to say, in the processing that step F 410 is carried out, at first, update stored in TDFL and TDDS among the cache memory 60a.Then, produce according to the TDMS updating block of the renewal of TDFL and TDDS and incrementally be recorded among the TDMA or ATDMA on the CD 1.
On the other hand, if the definite result's indication that produces does not have enough free areas in ISA or OSA,, carry out the replacement address process of using user data area so in the processing that step F 408 is carried out as being used to carry out the enough big district that replaces address process.
In this case, the flow process of processing proceeds to step F 411, produces the definite result who whether comprises NWA about target SRR in this step.Target SRR is SRR that finds in the processing that step F 401 is carried out or the SRR that comprises above-mentioned replacement target source address.That is to say that in this step, in order to produce the definite result who opens about target SRR or close, system controller 60 is with reference to the information in the SRRI header.
If should determine that the result indicated SRR to open, the flow process of Chu Liing proceeds to step F 412 so, and in this step, the data that will be written on the CD 1 according to data write request are recorded in the district that originates in NWA.Then, the flow process of processing proceeds to step F 414, in this step, carries out required renewal and handles.
In this case, by using the district among the target SRR to carry out the replacement address process.Thus, upgrade TDFL and upgrade SRRI by the DOW clauses and subclauses being added to TDFL by upgrading the SRR clauses and subclauses.Then, therefore TDDS also has been updated.That is to say, in the processing that step F 414 is carried out, at first, update stored in TDFL, SRRI and TDDS among the cache memory 60a.Then, produce according to TDMS updating block, SRRI and the TDDS of the renewal of TDFL and incrementally be recorded among the TDMA or ATDMA on the CD 1.
On the other hand, if the definite SRR of indicating target as a result that produces in the processing that step F 411 is carried out closes, the flow process of Chu Liing proceeds to step F 413 so.In this step, to be written to data on the CD 1 according to data write request and be recorded in the district of the maximum NWA among the NWA that starts from opening SRR.
When finishing the processing of record data, the flow process of processing proceeds to step F 414, in this step, carries out above-mentioned required renewal and handles.That is to say, in the processing that step F 414 is carried out, at first, update stored in TDFL, SRRI and TDDS among the cache memory 60a.Then, produce according to TDMS updating block, SRRI and the TDDS of the renewal of TDFL and incrementally be recorded among the TDMA or ATDMA on the CD 1.
As mentioned above, flowcharting shown in Figure 25 is in response to just in time being the request of processing of address of the address of having write down and the performed replacement address process of new data more to writing data into.Yet, should be noted in the discussion above that in response to write data into just in time be the address in the defect area the address processing request and new data more can also be carried out the replacement address process in an identical manner.
For example, supposing, even be address in Unrecorded bunch for data being write address specified in the request of the processing on the CD 1, but bunch is defective, makes and data correctly can not be write wherein.In this case, the flow process of processing proceeds to step F 406 from step F 403, carries out identical replacement address process in this step and subsequently step.
Yet,,, upgrade TDFL by listing new DFL clauses and subclauses in the mode identical with the DOW clauses and subclauses by the TDMS updating block of incremental record carrying out in the situation of replacing address process for this defect cluster.
6-2: data write processing second example
Below, by being described with reference to process flow diagram shown in Figure 26, other typical data write processing.More the data of explaining by the process flow diagram among reference Figure 22 as the front are write processing, and this other typical data is write to deal with and should be used in the problem that the fact caused that does not need to obtain NWA before the request of sending the processing of data recording to the CD 1.
Figure 26 shows processing is write in expression by the data of system controller 60 execution process flow diagram.Yet, because step F 401 to F410 is identical with step in the process flow diagram shown in Figure 25, so the description of these steps no longer repeats.
Write in the situation of processing in the data of flowcharting shown in Figure 26, if the address of appointment is the address of having write down in the data write request, the free area is present among TDMA or the ATDMA, and in ISA or OSA, there is not the free area, in order to use user data area to carry out the replacement address process, the flow process of processing proceeds to step F 411A so.In this step, check SRR is to produce about NWA whether be included in definite result among the SRR that is different from the SRR that comprises address specified in the data write request.
Should be noted in the discussion above that at least two SRR are in open mode usually.Therefore the definite result who produces in the processing that step F 411A carries out does not almost negate.Yet, be unique SRR that is in open mode if be included in the SRR of the address of appointment in the data write request, the definite result who produces in the processing that step F 411A carries out negates so.In this case, the flow process of processing proceeds to step F 407, in this step, before writing the end of run of processing by the data of this flowcharting, sends error message to the application of sending data write request.
If determine that the result determines that NWA is included in and is different among the SRR that comprises the SRR of the address of appointment in the data write request, the flow process of Chu Liing proceeds to step F 412A so, in this step, the data that will be written to CD 1 according to data write request are written among other SRR in the district that originates in NWA.That is to say, carry out as Data Update replacement address process that handle, that use the district among other SRR.Then, at next step F414, upgrade TDFL and TDDS according to replacing address process.Thereafter, the SRRI of the content of the SRR of goal displacement SRR also is updated with sample as an alternative.
In write data flowcharting shown in Figure 26, that be directed to data write request was handled, the address of appointment was the address of having write down in the data write request, and therefore carried out and replace address process to upgrade the data that have been recorded on this address.Should be noted in the discussion above that the address for appointment in data write request is the situation of the address of defect area, also can carry out the replacement address process in an identical manner.For example, suppose that even the address of appointment is address in not writing down bunch in the request of data being write the processing on the CD 1, this bunch is defective, makes correctly data to be write wherein.In this case, the flow process of handling proceeds to step F 406 from step F 403, to use ISA or OSA to carry out identical replacement address process, if perhaps in ISA or OSA, no longer there is the free area, in step F 406 and step subsequently, use and carry out identical replacement address process as the district among other SRR of interface target displacement zone.
When consuming to use to carry out and replace destination address when handling, carry out the processing of front by explaining with reference to Figure 21 as the district among the SRR of interface target displacement zone owing to ISA and OSA are write processing by these data.Therefore, can solve 20 described as earlier in respect of figures, owing to will use the incorrect supposition done supposition as NWA, and the problem that produces unnecessary DOW clauses and subclauses lavishly that causes.
6-3: data are read to handle
Comprising for the form of CD 1 wherein that the data of the situation in the replacement goal displacement district among ISA and the OSA are read to handle reads to handle identical with the data of flowcharting shown in Figure 23.
7: the effect of embodiment
As mentioned above, this embodiment realizes data recording to the replacement address function that has on the dish that does not comprise the form of replacing the district.In situation, can realize having high efficiency with the replacement address function of data recording to the CD with the CD that comprises the form of replacing the district.
That is to say, for the defective of expanding in Write-once disc and the data recording/reproducing device is replaced address function and Data Update function, these functions of realization as described below.
The form with the DFL clauses and subclauses of replacing the replacement address information in the address process as defective is identical basically for the form of the DOW clauses and subclauses of the replacement address information in handling as Data Update.
The DOW and the DFL clauses and subclauses that are used separately as the replacement address information in Data Update processing and the defective replacement address process all are recorded in TDFL upward as the information bar on the TDFL that co-exists in the management information that is used for storage defect replacement address process.
Replace the replacement goal displacement district of address process and Data Update processing as defective, not only can use the defective on the CD 1 to replace the district, also can use the track (perhaps SRR) that is present in the user data area, as the track that comprises the NWA that may be selected to be the appendix measuring point (perhaps SRR).
Replace address function and Data Update function by expanding aforesaid defective, can not realize that also Data Update is handled and defective is replaced address process even do not exist to replace to distinguish.
And, in the situation that comprises the form of replacing the district, be reduced to when no longer being enough to store the value of data even replace the memory capacity in district, also can carry out Data Update processing and defective and replace address process.
In addition, if will be placed on the Data Update function according to the CD 1 of embodiment does not have on the device of expansion, this device is explained the DOW clauses and subclauses as the replacement address information in the Data Update processing, these clauses and subclauses are as the DFL clauses and subclauses of replacing the replacement address information in the address process as defective, and the replacement goal displacement district read data of appointment in replacing address information.That is to say, owing to carried out conventional Request Processing, be placed on device, in having the device that the Data Update function is not expanded, also keep reproduction compatibility even finish the CD 1 of the operation of the replacement address function that is used for Data Update.
And the NWA as the appendix measuring point that can select to be present among the SRR replaces the replacement goal displacement address of address process as being used for Data Update processing and defective.
By selecting NWA, it is present among the SRR as the appendix measuring point, instead the replacement goal displacement address of the address in the replacement district among ISA or the OSA.
First aspect, adopt recording processing by using common file system to carry out, consider processing in the management information of disc recording file and renewal this document, the search distance of pick-up can be shortened enough little value, is used for compensation and replaces address process pick-up is moved to replacement goal displacement district.As an alternative, the management information of file can be recorded in the district that follows data.Therefore, can improve record performance.
In this case, selected last appendix measuring point as replacement goal displacement address is considered to effectively replace the goal displacement address.So last appendix measuring point elected as the replacement goal displacement address in the processing of in the step F 413 of the step F 110 of process flow diagram shown in Figure 19 or process flow diagram shown in Figure 25, carrying out.
Second aspect is being read in the processing of piece from replace the goal displacement address owing to detected defective in recording processing, because the short distance of searching of pick-up has been improved the reproduction performance.In this case, appendix measuring point in the SRR identical with replacing the target source address, selected goal displacement as an alternative address is considered to effectively replace the goal displacement address.In the processing that the step F 412 of the step F 109 of process flow diagram shown in Figure 19 or process flow diagram shown in Figure 25 is carried out, the selected goal displacement as an alternative of appendix measuring point address in the SRR identical, such with replacing the target source address.
In addition, if will be present in be different among the SRR that comprises the SRR that replaces the target source address, select goal displacement address as an alternative as the appendix measuring point of the NWA of another SRR, then can eliminate since in some environment by the problem that unnecessarily increases the DOW clauses and subclauses that generation caused of using the continuous unnecessary Data Update of initiating.Data in the flowcharting shown in Figure 22 or 26 are write in the processing, will be present in be different among the SRR that comprises the SRR that replaces the target source address, select goal displacement address as an alternative as the appendix measuring point of the NWA of another SRR.
Should be noted in the discussion above that then the physical record data are suitable under the following conditions if carried out by the data of the flowcharting shown in Figure 22 or 26 and write processing:
For the application that operates on the host apparatus, on CD 1, distribute at least two SRR that open, and will be different from appendix measuring point among the SRR of the SRR with defect area or experience Data Update and select address as the data that are used for the replacement goal displacement address of defective or are updated.
In addition, in the situation of form that distribute not replace the district, in using etc., needn't pre-estimate the size in suitable replacement district again.Needn't reallocate and replace effective utilization that the fact of distinguishing means user data area.
Even in the form situation of distribute replacing the district, all distribution are replaced the district and the district of user data area can be selected distinguish as an alternative once using up in addition.Therefore, needn't in application, pre-estimate the size in suitable replacement district.The fact that needn't estimate the size in suitable replacement district again means needn't distribute excessive replacement district, makes and can use the data field expeditiously.
In addition, in the situation of this embodiment, in order to make disk drive or data recording/reproducing device produce about the address on the CD 1 is the address in the district that write down or definite result of the address in Unrecorded district, in the appendix recording method, the SRRI (continuous recording range information) that disk drive or data recording/reproducing device use the address of having write down for management or Unrecorded address to provide.The district that has write down is the district that has write down data, and Unrecorded district is the district that does not have record data.Usually, orbit information, for example SRRI comprises three parts, that is, and the NWA of start address, end address and SRR (new write address or appendix record) point.
In the appendix recording method of using SRR (perhaps track), must be always in originating in as the district of the NWA of the appendix measuring point of SRR record data.This is to be confirmed as the district of record data because of the district that is present in the start address of SRR and be right after between the address before the appendix measuring point of SRR, and simultaneously, the district between the end address of appendix measuring point and SRR is confirmed as also not having the district of record data.Therefore, by adopting the appendix recording method, in the situation of the CD 1 that comprises the data that write down thereon, by obtaining about being present in the information of all SRR on the CD 1, disk drive can produce about write or read command in the address of appointment be the address of having write down or definite result of unwritten address.
In addition, in order to improve the reliability of replacing address management information, must increase and upgrade the number of times of replacing address management information.If being used as the size that is used to upgrade the TDMA that replaces address management information only is 2048 bunches, need so to distribute to make and to upgrade the Geng Da district that replaces address management information.
Should be noted in the discussion above that the form shown in Fig. 1 (a) has been introduced allows to replace the structure that a part that the district is provided with is set to ATDMA (additional temporary defect management area) when initialization.Yet,, replace the CD of distinguishing 1 not comprising shown in Fig. 1 (b) so this method can not be applied to not having because this method adopts the distribution in the replacement district that is called OSA as prerequisite.
Therefore, in the situation that does not comprise the form of replacing the district shown in Fig. 1 (b), be used in the method in the district of the multiple optical disc information on the management CD 1 as branch, adopt the technology that allows ATDMA, it is to be independent of the directorial area of replacing the district, is dispensed on the position in the decline of user data area.
In the situation of the Write-once disc of blu-ray type, carry out special formatting command and do not comprise the CD of replacing the district to produce.
Because the format parameter of this special order does not comprise the parameter of specifying common replacement district, so by specifying the maximum storage capacity that covers all addresses distributed to come formatting optical disc.Yet, by clearly specifying the value be slightly smaller than maximum storage capacity, can expand the function of disk drive, so that provide generation not have performance in the end of user data area to the district of its addresses distributed as memory capacity.
That is to say that in the situation of this embodiment, this district is used as the standby replacement address directorial area that is called ATDMA.
And, at this moment, disk drive also be provided with increase be called as the TDMA indicator expand to TDMA begin locate and in the TDMA indicator record about the information of ATDMA and the function of out of Memory.
The TDMA indicator has by disk drive with high-efficiency operation to find the function of the position that is used to write down up-to-date TDMS.In the processing of detection dish shown in Figure 24, disk drive is usually with reference to this TDMA indicator, to obtain the information about ATDMA when the detection dish.Thus, disk drive can be handled the ATDMA of the situation of not replacing district's existence.
From top explanation obviously as seen, even in the situation that the form of replacing the district is not provided and even providing in the situation of the form of replacing the district, the compatibility that this embodiment can keep record and reproduce, and do not change the physical format of Write-once disc and physical layout and limitation function not basically.
And, by keeping record and the reproduction compatibility with traditional Write-once disc, RAM type dish and ROM type dish as it is, can realize in not comprising the Write-once disc of replacing the district that data write function.
Therefore, the file system that being generally RAM type dish and ROM type dish usually provides can also be used to Write-once optical disc, and does not need to change hardware and physical format.
In addition, those skilled in the art should be understandable that, drop within claims or its scope of equal value according to them, can carry out multiple modification, combination, sub-portfolio and replacement according to design requirement and other factors.
