Embodiment
For complete understanding the present invention, its exemplary embodiment will be described with reference to the drawings.For convenience, disposable Blu-ray Disc will be as the example of the one-time write recording medium in the exemplary embodiment.
The data structure of recording medium
Fig. 1 and 2 has illustrated the data structure according to the Write once optical disc of the embodiment of the invention, and more specifically, interim disc management information.Being configured among the korean patent application No.2003-15634 of Write once optical disc as shown in Figure 1 described in detail.
As shown in the figure, the Write once optical disc in this example is the single-layer optical disc with a recording layer.This CD comprises the spare area (ISA0/ISA1) that is used for record data, because the defective in the main data area (for example, physical imperfection) can not write down these data in the main data area.The information that is used to manage with the defect part in the part replacement data district of spare area is recorded in temporary defect management area (TDMA).
Usually, relative with one-time write, CD-RW has limited defect management (DMA), and this is because of can repeatedly data being write DMA and wiping from it.Write once optical disc needs big quantity space with managing defect, and this is because only can the one-time write data and can not wipe.Therefore, TDMA is used for during using CD, recording defect management information when this information changes.In case finish CD, the final version of defect management information copied to DMA from the TDMA on the Write once optical disc.
With reference to figure 1, TDMA comprises TDMA1 that distributes to the introducing district with fixed size and the TDMA2 that distributes to spare area OSA0.TDMA2 has the size that the size with the spare area is associated.For example, the size of spare area OSA0 is N * 256 bunch, and wherein TDMA2 forms P bunch.The number of bunch P can be determined according to expression formula P=(N*256)/4.In each TDMA, write down temporary defect management information, interim disc definition structure (TDDS) and CD user mode information with temporary defect list (TDFL) form.
As mentioned above, when existing in the data field in the defect area, replace defective district, spare area (ISA0/OSA0).TDFL provides information to manage this process with tabular form.For example, the spare area of tabulation indication defect area and replacement defect area.According to one embodiment of present invention, from 1 to 4 bunch of variation of the size of TDFL is according to the quantity of information in TDFL.By contrast, according to an example of the present invention embodiment, the amount of space that gives TDDS is maintained fixed in cluster.According to this embodiment, this data block comprises TDDS and CD user mode information, and this will be below with reference to figure 2, and 5A-5B and 7A-7B describe in detail.From following detailed description as can be seen, according to the logging mode of Write once optical disc, CD user mode information can be journal information (for example, orbit information) or space bit map.
At first with reference to figure 2, the disc management information of existing CD-RW will be compared with the content that comprises in TDDS of the present invention.
In the situation of CD-RW, DDS consumes very little a part of CD, about 60 bytes of cluster (cluster has 32 sectors).The remaining area of this bunch is set by " zero padding ".But according to this embodiment of the invention, remaining area and the zone (60 bytes) that is used in the existing CD-RW are used as disc management information.Therefore, in TDDS of the present invention, journal is for Write once optical disc information specific and the DDS that is used in the existing CD-RW in a sector (2048 bytes).The logging mode designator that for example, can comprise the logging mode of recording medium in a plurality of possible logging modes of indication for the Write once optical disc information specific.This logging mode and logging mode designator will go through below.This information can also comprise the positional information of last TDFL.
As illustrated in fig. 1 and 2, CD user mode information (for example, being discussed below the journal information and the space bit map such as orbit information of the logging mode that depends on recording medium) is recorded in 31 sectors of residue of the cluster that comprises TDDS.As what select, can be in 31 sectors of the front of TDDS configuration CD user mode information, and, dispose TDDS on the 32nd sector last.CD user mode information changes the use of CD according to the user, and will be discussed in more detail below, but its provide can be used for by record/discriminating of unwritten area information comes the information of the other posting field of precise search.
Therefore, the TDDS that uses in the disclosure will constitute as mentioned above widely, and not be the project according to a specific criteria definition.
Logging mode and initial method
Fig. 3 has illustrated based on the CD initial method according to the logging mode of the embodiment of the invention.
As mentioned above, even the invention is intended to also support multiple recording method about Write once optical disc, and method is " sequential recordng mode " and " recorded at random pattern ".
" sequential recordng mode " is DAO (disposable CD) pattern that is used for the whole CD of disposable recording that adopted by the CD one-time write standard of prior art, and the logging mode that is used for the incremental record pattern of journal information on the continuous recording zone of CD.In sequential recordng mode of the present invention, but the number of the other posting field in CD is not limit in the incremental record pattern.The continuous recording of wherein journal data will be called as the track in the disclosure, and journal information can be called as orbit information.This orbit information will be discussed in more detail below.
" recorded at random pattern " is to make it possible to the logging mode that freely writes down on the whole zone of CD.In other words, this pattern is not limited in the order of the posting field identifying recording layer of CD.Here, usage space position mapping (SBM) is as the recording status of CD user mode information with the indication CD.This SBM will be discussed in more detail below.
Because the present invention supports aforesaid a plurality of recording method, when at first using Write once optical disc, determine logging mode, and the initialization CD is a logging mode.In other words, user, disc manufacturer, or the logging mode of main frame (integrally being called main frame hereinafter) decision CD, and in the cura specialis zone of CD, logging mode is set.Especially, if the logging mode of main frame input CD, optical disc recording system is provided with a byte with the indication logging mode in TDDS, and form definite and the CD user mode information that logging mode is associated.For example, if logging mode is a logging mode in proper order, system is provided with logging mode and is " 0000 0000b ", and " orbit information " is set is user mode information.If logging mode is the recorded at random pattern, system is provided with logging mode and is " 0000 0001b ", and setting " SBM " is a user mode information.Therefore, when after when using CD, system according to the logging mode record data of determining, and upgrades the management information of one of corresponding user mode information as CD on CD.
Therefore, if finish initialization and be written into Write once optical disc, the logging mode of corresponding CD is at first judged by system, judges one that determines in a plurality of CD user mode information according to logging mode, and upgrades the user mode information of determining in the CD managing zone that is provided with in corresponding CD.
Hereinafter, will describe and the logging mode detailed structure and the recording method of " orbit information " and " SBM " of management that be associated, and be described in the method that writes down TDDS and TDFL among TDMA and the DMA afterwards.
The track kind
With reference to figure 4, described according to the track of the CD of the embodiment of the invention and the kind of physical arrangement.The continuous recording district of wherein journal data will be called as track in the disclosure.Fig. 4 has illustrated according to the present invention different types of primary track of the Write once optical disc of example embodiment.Say that more specifically Fig. 4 has illustrated that supposition use Write once optical disc a period of time has a plurality of continuous recordings district or the track of different conditions.As shown in Figure 4, track 1 and 2 is corresponding to open tracks, and they are when its first area storage data, and each all has the back region that can carry out addition record on it. Track 3 and 4 is corresponding to finishing or close closed orbit, and it is (track 4) that is full of fully or (track 3) of closing for further record.Shown in track 3, to close when track and to make when not allowing in track, to write down with unwritten zone, unwritten zone is with zero padding (shown in the dash area of Fig. 4), and changes into and finish track.Track 3 is different from track 4 in this.
Each track has the track (LRA) of last record, and ignores the track kind.LRA is the FA final address of record real data in track.Therefore, about track 3, the position before track 3 (or address) is the LRA (LRA3) of track 3 with zero padding.More specifically say, suppose that the unit that is used at the CD identifying recording layer is bunch, and in one bunch, have 32 sectors.If, remain the sector so with zero padding less than 32 sectors record data therein.Last sevtor address before filling is LRA.Open and intermediate orbit for each, but whether close closed orbit, but determine that designation data writes the next one write address (NWA) of next address wherein.Obtain NWA as the next sevtor address after the LRA from LRA.
The data structure of the orbit information on the recording medium
At first, the present invention does not limit the number of open tracks.Therefore, can there be a plurality of open tracks and finish track.The invention provides the data structure that on recording medium, is used for managing this effect with effective means.Shown in Fig. 5 A, the logging mode designator indication sequential recordng mode in TDDS, and CD user mode information is orbit information.The embodiment of this track information data structure will be described in detail with reference to figure 5B below.
As shown in the figure, journal, or say that more specifically orbit information comprises three parts: the designation data structure provides the header of orbit information; The track information list of orbit information and the full stop of ending of indication orbit information are provided.
Header is positioned at the front portion of orbit information, and comprises that the information of indication after identifier is orbit information " orbit information structural identifier ".The form of next designator " track information format " indication orbit information.It after this " level number (0 or 1) " field of recording layer of expression orbit information correspondence.Thus much example is for the Write once optical disc of a side, single recording layer, and CD can have a plurality of recording layers and/or be bilateral.
Header further comprises " track sum " field of the number of tracks in the data field of recording layer of expression orbit information correspondence and is illustrated in " open tracks sum " field of the number of open tracks in this data field.Before reading track information list, can confirm total orbit information.
Track record information list after header, and will be described in greater detail below.The track information list full stop is represented the ending of orbit information.Therefore, orbit information comprises header, track information list and the full stop of record continuously.
To the example embodiment of track information list be described in further detail.Track information list is included in clauses and subclauses of each track in the corresponding data district of CD.Each clauses and subclauses can be distributed to, for example, and 8 bytes.This track information entry comprises the address information of the last record of first address of track status information, respective rail and track.
Kind-opening of track status information indication track, close or the centre, and can represent, shown in Fig. 3 B by 4 bits.In this embodiment of the present invention, wherein can carry out the open tracks of addition record and indicate, and wherein not allow the track of finishing of addition record to indicate by " 1000b " as track status information by " 0000b " as track status information.Track status information is represented as above-mentioned specific bit, with the track information list entries that helps classification as will describe below in the disclosure.
In the example of Fig. 5 B, first address information of clauses and subclauses is " the beginning physical sector number (PSN) of track " fields.This field provides the sevtor address of first sector that forms track.The address information of last record is the LRA of track in the example of Fig. 5 B.Therefore, if read clauses and subclauses, can determine the kind of track, the LRA of starting position and track.
Track status information in each clauses and subclauses comprises that also session begins bit (for example, one of bit in the track status information in each clauses and subclauses can begin bit as session).Whether session status indication track is first track in the session.Here, the track gathering is called as session in groups.
Space bit map structure and recording method
Fig. 6 schematically illustrates the wherein direction of the zones of different of recording disk.This explains that the understanding for the data structure of following SBM about Fig. 7 A and 7B is helpful.
Though Fig. 1 has illustrated the example of single-layer optical disc, BD-WO can have a plurality of recording layers.Usually, the aspect according to single-layer optical disc of the present invention can be applied to bilayer.For the purpose of explaining, Fig. 6 has schematically illustrated Write once optical disc, such as a plurality of layers in each zone among the BD-WO.
In the BD-WO of Fig. 6, can exist first and second the record layer by layer 0 and the layer 1 (being called " L0 " and " L1 " hereinafter).Each recording layer comprises inner area, inner spare area, user area, outer spare area and outside area.In the situation of double-layer CD, the inner area of the first recording layer L0 becomes introduces the district, and the inner area of the second recording layer L1 becomes the draw-out area.But in the situation of single-layer optical disc, outside area will be to read the district.
Fig. 6 has illustrated that circumference uses the first recording layer L0 to outer circumferential internally, and only uses its outer spare area OSA0 from the outer circumferential to the inner periphery.From the outer circumferential to the inner periphery, use the second recording layer L1, and only internally circumference use its inner spare area ISA1 to outer circumferential.Therefore, determine the starting position that each is regional according to the service orientation in zone.But this is only corresponding to the service efficiency of CD, and if each regional service orientation change, the starting position in zone also changes.
In each regional service orientation of CD and starting position as defined above in the situation, will describe the method for the SBM that indication changes according to the user mode of CD in detail.
Shown in Fig. 7 A, logging mode designator indication recorded at random pattern and CD user mode information among the TDDS are SMB.Fig. 7 B has illustrated the example of the data structure of SBM.As shown in the figure, SBM comprises three steps: make it possible to discern the header of SBM, be used for the SBM full stop of directly indicating the SBM information of SBM and being used to notify the ending of SBM.
Header is the SBM except discerning this information field, also comprises recording layer information field and format version field.Recording layer information field indication SBM and which recording layer (for example, level number 0 or 1) are relevant.Which format version format version field indication SBM meets.
Shown in Fig. 4 B, prepare SBM information for the zone of each division of CD, and determine whether to upgrade SBM according to the needs of user, disc manufacturer or main frame (set be called main frame) hereinafter.Specifically, SBM information comprises each regional start position information (a beginning bunch PSN), the length information of respective regions, the bit mapped data that each is regional.In an example embodiment, start position information and length information are set, and only the updated space map information is once.This method is called as SBM opening/closing function, and is used for the multiple request of effective processing host.And, in the situation of BD-WO, if environment for use corresponding to real time record, is not carried out defect management.In this case, be regardless of and join the spare area, and do not need to upgrade the SBM of respective regions.
And in a particular case, only conduct is wherein managed by SBM the user area of user data, and does not upgrade SBM to change into other zone.All upgrading SBM because if no matter when change management information, will be useful according to the operation of this embodiment, need be to the frequent updating of SBM.This embodiment can prevent to use fast the available TDMA zone on the light CD.Therefore, only use the SBM of SBM opening/closing function executing user data area to upgrade if desired, and do not upgrade remaining area, start position information and length information that other is regional are set to particular value, for example, are made as " zero " value.
As mentioned above, by each renewal of SBM, the new SBM+TDDS data block of record in TDMA, wherein SBM provides the accumulation indication of the recording status of CD.Same, by each renewal of SBM, upgrade TDDS; Particularly, the reposition of indication SBM.
The orbit information update method
When upgrade CD user mode information and can be the design parameter of setting up according to system or system designer.But the example that triggers the time of upgrading will be discussed in more detail below.
When in sequential recordng mode, producing new-track or closing closed orbit,, can upgrade orbit information because newly produce orbit information.Similarly, but when during recorded at random, changing new posting field, renewal SBM.When ejecting CD from driver or being cut to the power supply of driver, stop using CD at least temporarily.In these times, upgrade orbit information.
TDMA and DMA recording method
Fig. 8 and 9 has illustrated the example embodiment according to method for recording information among TDMA of the present invention and the DMA respectively.Fig. 8 has illustrated the information at CD operating period interocclusal record TDDS, the method for the TDFL among CD user mode information and the TDMA, and if Fig. 9 illustrated finish information that CD conversion writes down in TDMA finally or current version be DMA.
Fig. 8 has only illustrated the situation of TDMA1, and it exists in introducing the district.But, clearly carrying out among the TDMA that the present invention can exist in other zone of CD, TDFL and TDDS are recorded among the TDMA by following method.
With the generation journal and the management TDFL of defect area, and ignore recording layer, and it has variable-size.In other words, when because the cause of the increase of defect area record through bunch 1 the time, the size of TDFL can be increased to 8 bunches from 1.When using multilayer BD-WO, consider the number that whole CD capacity obtains bunch (for example, for 4 bunches of single-recordng-layer CDs, and for 8 bunches of double record layer CDs).
Afterwards, will have the TDDS of fixed size for pluratity of recording layers record and management separately.That is, after TDFL as shown in Figure 8, replace the TDDS of record for each recording layer.The fact that this writes down separately in each recording layer corresponding to " orbit information " and " SBM " quilt with the TDDS record.And, in TDDS, feasible " positional information of up-to-date TDFL (4 byte) " and " up-to-date TDDS positional information (4 byte) " that writes down other recording layer therein in range of distribution.No matter when upgrade TDDS, upgrade above-mentioned information.Therefore, by reading the TDDS information (ignoring recording layer) of last record, can confirm all information on corresponding CD, for example, the video disc recording pattern of other recording layer, up-to-date user mode information (orbit information or SBM), up-to-date TDFL positional information, up-to-date TDDS positional information is to realize effective management of CD.
Fig. 9 has illustrated the only data recording of the situation of the DMA1 of existence and DMA2 in introducing the district.But, executive logging method among the DMA that can also in other zone of CD, exist clearly.
At first, record among the DMA can not (when becoming full, TDMA or spare area may take place) or can carry out when further record when the user finishes CD alternatively.Last TDDS (having CD user mode information)/TDFL during the content that in DMA, writes down among the TDMA.This information is converted into the DDS/DFL information of DMA.Therefore, record TDDS/TDFL information in DDS/DFL is just as not changing recorded content.DDS/DFL means the final entry of CD among the DMA, and has structure identical with TDDS/TDFL and content.
According to the present invention, by following method record DDS and DFL.
The DMA of an example embodiment comprises 64 bunches in the situation of pluratity of recording layers according to the present invention.8 guiding bunch zones that are provided for writing down DDS information, and 54 remaining bunch of zones that are provided for writing down DFL information.
DDS in DMA has the structure identical with TDDS.Bunch 1 sector, top 1 at DDS, the zone of the identical information that is provided for writing down and in BD-RE, uses, be used for writing down only be used in BD-WO information (for example, the video disc recording pattern of other recording layer, up-to-date user mode information (orbit information or SBM), up-to-date TDFL positional information, up-to-date TDDS positional information etc.).In 31 residue sectors, will be recorded in separately in each recording layer with logging mode " orbit information " or " SBM " that is defined as CD user mode information that be associated.
And, with the order execution sequence record of the TDDS (TDDS of L1) of the TDDS (TDDS of L0) of first recording layer and second recording layer, and carry out duplicate record with the order of the TDDS (TDDS of L0) of the TDDS (TDDS of L1) of second recording layer and first recording layer afterwards.This recording method is for the practical structures of CD counting, and with respect to because the cause of the direction (that is horizontal direction) of cut and the probability that damages dma information is prepared in the CD.
And, because the DFL among the DMA has and the last identical content of TDFL, and use maximum 8 bunches of record TDFL, can carry out its duplicate record with the required number of times of system.At this moment, the number of times maximum of repetition is 7.
As mentioned above, according to of the present invention on Write once optical disc the method for records management information make it possible to carry out selectivity record according to the CD user mode information (" orbit information " and " SBM ") of the logging mode of determining, and make it possible to effective recorded information in TDMA and DMA, and can realize that therefore the CD of effective and stepping uses.
