SUMMARY OF THE INVENTION Example embodiments of the present invention provide a PAC cluster on a medium, such as a high density optical disc, and apparatus and methods for recording data to and reproducing data from the medium using a PAC cluster.
FIG. 5 illustrates a configuration of an �Unknown PAC Rules� field according to an example embodiment of the present invention;
DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS OF THE INVENTION Reference will now be made in detail to example embodiments of the present invention, which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
In an example embodiment, in addition to its ordinary and customary meaning, the term �physical access control (PAC)� may also include additional information being recorded on the disc for managing/controlling data recording and reproduction for an entire disc or a specific segment within a physical zone of the disc. The term �physical access control (PAC)� may be referred to as �PAC�, �PAC information�, and/or �PAC control information� for simplicity. In addition, a zone within the disc on which the PAC is recorded may be referred to as a �PAC zone� and the PAC being recording in the PAC zone in cluster units may be referred to as a �PAC cluster� for simplicity. Furthermore, a PAC according to example embodiments of the present invention may include an �unknown rule�, which may restrict read/write of data for the entire disc or a specific segment, for a drive having a specifically unknown PAC_ID and including a drive of a previous version (for example, a �legacy� version�). A PAC having an �unknown rule� applied thereto may be referred to as an �Unknown PAC�. Similarly, a known specific PAC_ID recorded on the PAC may be referred to as a �known rule� and �PAC specific information� that is applied to the PAC may be referred to as a �Known PAC�.
As described above, the PAC zone may controls read/write of data for the entire disc or a specific segment and, therefore, may include an �unknown rule� for restricting the read/write functions of a drive. The area of the disc being controlled by the �unknown rule� may include a disc management area (DMA), a spare area, a user data area, and/or other relevant areas. More specifically, the user data area can be sectioned into segment areas defined on the disc, to which the �unknown rule� may be applied. Segments are discussed in more detail below.
An �unknown rule� may be used to ensure predictable operations of the disc, and may include controls for operation, such as reads, writes, and/or other similar operations, for linear replacement of a defective zone, logical overwrite of the high density optical write-once disc, and/or other similar operations. An area may be provided on the disc where the �unknown rule� is applicable, having segments for defining an entire disc, or a specific segment of the disc. Therefore, by defining an area a previous version drive (or legacy drive) is able to access by using the �unknown rule� of a PAC recorded in a PAC zone, a newer version of the optical disc can resolve any problems that may occur, but cannot be identified in a previous version, such as reducing unnecessary access operations of the previous version drive. Moreover, by defining an accessible area on a physical area of the disc for the previous version drive to access using a PAC, a data area having user data recorded thereon can be protected more robustly and/or unauthorized access (for example, hacking) of the disc may be prevented or reduced.
FIG. 3 illustrates a physical access control (PAC) recordable on a high density optical write-once disc according to an example embodiment of the present invention. Referring to FIG. 3, one PAC of one cluster size (32 frames or sectors) may include a header zone and/or a specific information zone specific to a particular disc drive (for example, optical disc drive). The PAC header zone may have 384 bytes allocated to a first frame of the PAC, for recording various kinds of PAC information, such as information on an �unknown PAC rule� and segments, and another area of the PAC zone may have information specific to the optical disc drive, also referred to as a �known rule�, recorded thereon.
A more detailed structure of the above-mentioned example PAC having information recorded thereon is described with reference to FIG. 4. A more detailed description of a field of the PAC will follow with reference to a drawing illustrating the specific field corresponding to the PAC. FIG. 4 illustrates a PAC in a high density optical write-once disc according to an example embodiment of the present invention. Referring to FIG. 4, the PAC may include a header portion (up to 384 bytes of the first frame) and an area having specific information specific to the drive recorded thereon. More specifically, the header portion may include 3 bytes of �PAC_ID�, 1 byte of �PAC format�, 4 bytes of �PAC Update Account�, 4 bytes of �Unknown PAC Rules�, 1 byte of �Entire_Disc_Flags�, 1 byte of �Number of Segments�, and/or 32 �segments (Segment�0�Segment�31) each having 8 bytes.
The �PAC_ID� is a field that may include present PAC status and identification codes. For example, when the �PAC_ID� is recorded as �00 00 00h�, the �PAC_ID� may indicate that the present PAC is not used. In case of a re-writable high density optical disc, when the �PAC_ID� is recorded as �FF FF FFh�, the �PAC_ID� may act as a code indicating that the present PAC zone has been previously used but is available for additional use (i.e., usable once again). Moreover, by recording the �PAC_ID� in specific bits, such as �54 53 54h�, a �PAC_ID� can be used as a code for determining whether the present drive is capable of and/or permitted to have free and/or complete access to the disc. In other words, if the present drive is unable to acknowledge the �PAC_ID� applied as described above, then the present drive is determined to be incapable of acknowledging the inputted �PAC_ID� for some reason, such as mismatched versions. Thus, the �54 53 54h� bits may be used as a code requiring reference to information recorded on the �Unknown PAC Rules� field.
As described above, the �Unknown PAC Rules� field may be used as a field that designates an operation range of the drive that cannot acknowledge the present PAC, a more detailed description of which will follow with reference to FIG. 5. FIG. 5 illustrates a configuration of an �Unknown PAC Rules� field according to an example embodiment of the present invention. Referring to FIG. 5, control of and/or access to various areas on the disc may defined by an �Unknown PAC Rules� field, which may be expressed as 4 bytes (or 32 bits). In this example, the �Area� column in FIG. 5 represents the controllable/accessible areas on the disc, the �Number of bits� column represents the control bits, and the �Control type� column represents control types, such as read/write and/or other similar operations.
The controllable/accessible areas/zones of the �Unknown PAC Rules� field may include controls, such as write control of the �TDMA (excluding Temporary Disc Definition Structure (TDDS))�, write control of the �Spare Areas� within the data zones, write and read control of control data (CD) zones within the INFO zone, write and read control of a �Segment Area� when a �User Data Area� or a segment area is defined in the data zone, and/or write and read control of a �PAC cluster� within the INFO zone. By using fields, such as those defined above, a controllable area within the disc for a drive having an unknown PAC_ID can be designated using the �Unknown PAC Rules�. Therefore, the �Unknown PAC Rules� can be used for controlling access to the entire disc or a specific area within the physical zone of the disc, if there is a drive version mismatch or if the user wants to control access.
Returning to FIG. 4, a �PAC Update Count� field may be used to indicate a number of updates in the PAC (which may be initially set to �0�). The recorded number may be increased by one each time the PAC is re-written. The �Entire Disc Flag� field, shown in FIG. 4, may be used as a field applied to the entire area of the disc, regardless of the allocation of the segment area for the unknown PAC and may indicate whether re-initialization is allowed. In case of a high density optical write-once disc, re-initialization cannot be performed. In this case, the �Entire Disc Flag� field may be to indicate that the PAC is applicable to an entire area of the disc, and the �Number of Segments� field is a field representing a number of segment area the PAC is applicable to.
The �Number of Segments� field may indicate the number of segment areas being applied to the PAC. The segment may include a maximum number (for example, 32) of segments that can be allocated to one PAC. Information on the allocated segments may be written on fields of �Segment_0� to �Segment_31�, each which may include 8 bytes. The first physical sector number (PSN) of the first cluster in the segment area of the first 4 bytes may be recorded on each of the �Segment_0� field to the �Segment�31� field.
Segments are described in more detail with reference to FIG. 6. FIG. 6 illustrates segment zones in a high density optical disc according to an example embodiment of the present invention. Referring to FIG. 6, there can be a maximum number (for example, 32) of segment areas in succession starting from �segment 0� if required on a high density optical disc, for applying the PAC thereto. Up to the maximum number (for example, 32) of segments can be allocated starting from �segment 0� in an ascending order for management by one PAC, and even if there are a plurality of PACs, a total number of the segment areas managed by the PACs should not exceed the maximum number (for example, 32).
In this example, by writing a starting location of the allocated segment area as the first PSN of the first Cluster and the last location of the allocated segment area as the last PSN of the last Cluster on the �Segment� fields, the optical disc drive can determine locations of the segment areas. In this example, none of the plurality of segments allocated, and managed by one PAC overlap with one another, and the starting and last locations are designated at boundaries of clusters.
FIG. 7 illustrates a structure of a PAC zone in a high density optical write-once disc according to an example embodiment of the present invention. Referring to FIG. 7, a plurality of �Valid PACs�, each with one cluster size may be written on one PAC zone (a PAC zone of INFO2 or INFO1) of 32-cluster size, as required. A valid PAC may be a zone having various kinds of PAC information described above. A PAC that is not accessible by an optical disc drive, for reasons such as recording update, defect, and/or similar conditions, may be referred to as an �Invalid PAC�.
An example structure of a TDDS including various types of information related to the status of the PAC zone will now be described. FIG. 8 illustrates a TDDS structure in a high density optical write-one disc according to an example embodiment of the present invention. Referring to FIG. 8, the TDDS of the high density optical write-once disc may include a �TDDS Identifier� field, a �TDDS Format� field, a �Location of LSN 0 of User Data Area� field indicating the location of a logical sector number (LSN) 0 in the user data area, a �PAC Status L0� field indicating the status information of the PAC, and/or a �PAC Status L1� field indicating the PAC status information for a dual layer disc.
The �PAC Status L0� field may include a total of 16 bits and may be used as a PAC2 zone of the INFO2 zone, as well as a field indicating the status of the PAC existing in the PAC1 zone of the INFO1 zone. If the disc is a dual layer disc, the �PAC Status L1� field may be to indicate which layer of a dual layer disc the PAC is recorded on.
As shown in FIG. 9B, a single �PAC Status L0� field may use a total of 128 bits (or 16 bytes) to indicate the PAC status within the PAC2 zone of the INFO2 zone and the PAC1 zone of the INFO1 zone. In case of a dual layer disc, a total of 256 bits (or 32 bytes) may be used, since a �PAC Status L1� field may further be included therein. Accordingly, 2 bits may be used to represent information included in one PAC zone. For example, among the 64 bits having the PAC2 status information on the PAC Status Bitmap, bits b63 and b62 may contain the status information on PAC #1 (location 1) of the PAC2 zone, and bits b61 and b60 bits may contain the status information on PAC #2 (location 2) of the PAC2 zone. Sequentially allocated in a similar method, bits b1 and b0 bits may contain the status information on PAC #32 (location 32) of the PAC2 zone. In other words, 2 bits may be allocated to a PAC, thereby indicating the PAC status of the PAC2 zone. Similarly, the status information on the PAC1 zone may also be represented on the PAC Status Bitmap using the same method.
FIG. 9C illustrates the PAC status of a corresponding PAC zone represented by 2 bits. Referring to the example of FIG. 9C, when the 2 bits indicating the PAC status are �00�, the corresponding PAC is not recorded. When the 2 bits are �01�, the PAC is not used in a high density optical write-once disc. In case of a high density optical re-writable disc, the �01� bits can either be used as PAC_ID=00 00 00h indicating that the corresponding PAC has not been recorded, or a PAC_ID=FF FF FFh indicating that the PAC has been previously used but can be re-used. In addition, when the 2 bits are �10�, either the corresponding PAC zone is a defective zone or the bits are used to indicate that the corresponding PAC is an invalid PAC. When the 2 bits are �11�, the bits may be used to indicate that the corresponding PAC is a valid PAC.
Accordingly, the next recordable PAC zone is the PAC zone indicated by �00�, which indicate the PAC status in the �PAC Status� field, and the location of the defective zone or the invalid PAC becomes a PAC zone indicated by �10�. Further, the location of the valid PAC is a PAC zone indicated by �11�. By using the above described method, the optical disc drive can acquire information on the location of a valid PAC, the location of a defective zone or an invalid PAC, the location of the next recordable PAC zone, among the PACs recorded on the PAC2 zone and the PAC1 zone, through the �PAC Status� field of the 16 bytes (or 32 bytes when using the dual layer disc) inserted in the TDDS area. A more detailed description will follow below.
FIG. 10B illustrates an example PAC zone being recorded in a �PAC Status� field of a TDDS indicating the PAC status information. More specifically, in the PAC2 zone of the INFO2 zone, PAC #1 (location 1) is a valid PAC and is recorded as �11� in the corresponding field of the �PAC Status� field and PAC #2 (location 2) is an invalid PAC and is recorded as �10� in the corresponding field. Being unrecorded, the rest of the zone is recorded as �00� on the corresponding field, thereby indicating unrecorded status. Meanwhile, in the PAC1 zone of the INFO1 zone, because an error may have occurred during recording (for example, due to a defect), PAC #1 (location 1) is identified as a defective zone and �10� is recorded on the corresponding field of the �PAC Status� field, and a next PAC #2 (location 2) is a valid PAC and �11� is recorded on the corresponding field. A next PAC #3 (location 3) is an invalid PAC and �10� is recorded on the corresponding field. The rest of the zone is unrecorded and �00� is recorded on the corresponding field.
Moreover, when representing the status information of the PAC zone being recorded on the TDDS, a PAC may be recorded on identical locations on the PAC2 zone and the PAC1 zone, and so only the information of either one of the PAC2 and PAC1 zones can be indicated. A more detailed description will follow with reference to FIG. 11B. Referring to FIG. 11B, 8 bytes may be used in the �PAC Status� field of the TDDS (or 16 bytes when using a dual layer disc), and the indication of the status information of only one of the PAC2 zone and the PAC1 zone is required. When the status information is indicated by using 2 bitmaps, as described in the example embodiment shown in FIG. 9B, the 2 bitmaps may contain the same information. The 2-bit information being recorded is shown in FIG. 11C, which is represented by using the same example method described in FIG. 9C.
The PAC zone recorded as shown in FIG. 11A may be recorded in the �PAC status� field, as shown in FIG. 11D. More specifically, referring to FIG. 11D, in the PAC2 zone or the PAC1 zone, zone 1 (location 1) is an error zone and �10� is recorded in the corresponding field, zone 2 (location 2) is a valid PAC and �11� is recorded in the corresponding field, zone 3 (location 3) is an error zone and �10� is recorded in the corresponding field, and zone 4 (location 4) is a valid PAC and �11� is recorded in the corresponding field. The rest of the zone is unrecorded and �00� is recorded on the corresponding field.
FIG. 12 illustrates a method for displaying PAC status information on a TDDS when the recorded PAC according to an example embodiment of the present invention is updated. Referring to FIG. 12 and, more particularly, to part (a), a PAC may be recorded on the PAC2 zone of the INFO2 zone and the PAC1 zone of the INFO1 zone, and the PAC status information may be recorded in the �PAC Status� field of the TDDS. An example of a field having a single valid PAC (PAC 1) is described. For a PAC recorded as described above, an update of the recorded single valid PAC information may be required. In this example, when the optical disc is a high density optical re-writable disc, the information can be re-written using an overwriting method. However, in case of a high density optical write-once disc, an overwriting method cannot be used.
Therefore, when using a high density optical write-once disc, the updated valid PAC may be recorded on a next zone subsequent to the PAC 1, as shown in part (b) of FIG. 12. Eventually, the previously recorded PAC 1 become an invalid PAC, and the corresponding status information is updated from �11�, which initially indicated that PAC 1 was a valid PAC, to �10�. Also, since the newly updated next valid PAC 1 is updated from an initially unrecorded zone to a valid PAC, the PAC status is updated from �00� to �11�.
Further, as shown in part (c) of FIG. 12, when recording a next valid PAC 2, a copy of the valid PAC 2 may be recorded in the PAC1 zone of the INFO 1 zone. At this point, an error may occur during the process of recording the valid PAC 2 in the PAC1 zone of the INFO1 zone. If an error occurs, the valid PAC 2 may be recorded on a next recordable zone subsequent to the error zone. Accordingly, by recording the valid PAC 2, the PAC status information representing the PAC2 zone may be updated from �00�, which initially indicated that PAC 2 was an unrecorded zone, to �11�. Moreover, since an error occurred during the process of recording the valid PAC 2, the PAC status information representing the PAC1 zone may be updated from �00� to �10�. Further, because the valid PAC 2 is recorded on a next recordable zone, the PAC-status information is updated from �00� to �11�.
Although not shown, when an error occurs in a zone, which is initially a valid PAC at the time of reading, the status information may be updated from �11� to �10�. Furthermore, the TDDS information may be continuously updated as required, within the TDMA, prior to disc closing. Further, s mentioned previously, if the TDMA is insufficient, an additional TDMA may be allocated.
FIG. 13 illustrates a TDDS in a high density optical write-once disc according to another example embodiment of the present invention. Referring to FIG. 13, the TDDS of the high density optical write-once disc may include a �TDDS Identifier� field, a �TDDS Format� field, a �Location of LSN 0 of User Data Area� field indicating the location of a logical sector number (LSN) 0 in the user data area, a �Last LSN of User Data Area� field indicating the last logical sector number (LSN) in the user data area, a �PAC Clusters Defect Status� field indicating an error status of a PAC, and/or a �PAC Allocated Space� field indicating the allocated status of the PAC zone. Further, in the TDDS having the above-described example structure, the �PAC Clusters Defect Status� field and the �PAC Allocated Space� field may be used to indicate various types of PAC status information, such as the location of a cluster having a defective cluster and a valid PAC allocated therein in the PAC zone.
A method for indicating PAC status information by using a �PAC Clusters Defect Status� field and/or a �PAC Allocated Space� field will now be described in detail. FIGS. 14A and 14B illustrate a method for recording a PAC zone and PAC status information in the high density optical write-once disc according to another example embodiment of the present invention. Referring to FIG. 14A, a total number (for example, 32) of PACs can be recorded in a single PAC zone. For each of the recorded PACs, in order to indicate the defects in the PAC clusters, 32 bits may be used in the �PAC Clusters Defect Status� field, as shown in FIG. 14B. 64 bits may be required in order to also indicate the status of the PAC1 zone having the copy of the original PAC recorded thereon, and 128 bits may be required for a dual layer disc.
More specifically, referring to FIG. 14B, a PAC defect status (PDS) N bit may be used to indicate the defect status of a corresponding cluster. �0� may be used to indicate that the PAC cluster N is not a defective area, and �1� may be used to indicate that PAC cluster N is a defective area. PDS 31 bit and PDS 30 bit may be sequentially allocated to indicate the status of PAC #1 zone and PAC #2 zone, respectively. 32 PDS bits may be provided to indicate a possible defect status within the single PAC zone. In addition, 32 bits may be used in the �PAC Allocated Space� field in order to indicate the allocated status of the PAC zone. Similarly, 64 bits may be used in order to indicate the status of the PAC1 zone having a copy of the original PAC recorded thereon and 128 bits may be needed for a dual layer disc.
The PAC status bit (PSB) N bit, shown in FIG. 14B, may be used to indicate the allocated status of the PAC zone. �0� may be used to indicate that the PAC cluster N is in a newly allocatable status (e.g., the corresponding PAC is unused), and �1� may be used to indicate that the PAC cluster N has already been used. As shown in the description of the PDS bit, the PSB bits may be sequentially allocated from PAC #1 to PAC #30. PSB 31 bit may be used to indicate the status of PAC #1 zone, PSB 30 may be used to indicate the status of PAC #2 zone, and so on.
FIGS. 15A and 15B illustrate an example of a PAC zone and PAC status information recorded in a high density optical write-once disc according to another example embodiment of the present invention. Referring to FIG. 15A, PAC #1, PAC #2, and PAC #3 are allocated in the TDDS. Referring to FIG. 15B, when the PAC #2 is a defective area, the PDS bit indicating the PAC #2 zone in the bitmap of the �PAC Clusters Defect Status� field is recorded as �1�. The PSB 31, PSB 30, and PSB 29 each indicating the PAC #1, PAC #2, and PAC #3 zones, respectively, in the bitmap of the �PAC Allocated Space� field indicating the allocation status are also recorded as �1�. Accordingly, through the above-described example TDDS information, an optical disc driver can identify the PAC #4 zone as the next recordable zone.
FIG. 16 illustrates a block diagram of an apparatus for recording and/or reproducing in a high density optical write-once disc according to an example embodiment of the present invention. Referring to FIG. 16, the optical recording/reproducing apparatus may include a recording/reproducing device 10 for performing recording/reproduction to/from the optical disc, and a host, or controller 20 for controlling the recording/reproducing device 10. In an example embodiment, the recording/reproducing device 10 may act as the �optical disc drive� discussed above in conjunction with many example embodiments of the present invention.
The microcomputer 16 in the recording/reproducing device 10 may then receive the writing instruction, determine if the area of the optical disc the host 20 desires to write is a defective area or not from the management information stored in the memory 15, and perform data writing according to the writing instruction from the host 20 on an area which is not the defective area. If it is determined that writing on an entire disc or on a particular area of the disc includes new features which a previous version of the recording/reproducing device is not provided with, leading the previous version of the recording/reproducing device to fail to sense, or if it is intended to restrict functions, such as writing or reproducing to/from a particular area of the disc according to restriction set by the user, the microcomputer 16 of the recording/reproducing device 10 may write control information of the area in the PAC zone on the disc as an �Unknown PAC rule�. The microcomputer 16 of the recording/reproducing device 10 may also write PAC information, such as the PAC_ID for a written state, and segment information which is control information on the particular area of the disc.
If the PAC_ID is not identifiable, the method determines that the recording and reproducing device having written the data on the disc has a version different from the version of the present recording and reproducing device, and the recording/reproduction is preformed according to the instruction from the host with reference to recording/reproduction restriction areas on the disc including the �Unknown PAC rule�. Accordingly, the microcomputer 16 provides the location information and data according to the instruction from the host to the servo 14 and the data-processor 13, so that the recording/reproduction is finished at a desired location on the optical disc through the pickup part 11.
