DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0035] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts. [0036] Although the most widely used and general terms are chosen, terms arbitrarily chosen by the present inventor(s) are also used. In such cases, the present invention should be understood in view of the meanings of the terms as defined by the inventor(s). In this regard, the present inventor(s) define the term “track” to mean a sequential recording range (SRR) of a write-once optical disc such as a BD-WO, i.e., an area for recording data/information on the disc. As such, “track” and “SRR” are used interchangeable herein and each represents a unit of recording (a recording-unit). Consequently, the term “track information” (“Track-Info”) or “SRR information” (SRRI) is defined by the present inventor(s) as a general term that indicates a used status of the write-once optical disc. A session has at least one track/SRR, i.e., at least one recording-unit. The term “session information” is used as a general term for indicating a recorded status of a specific block in order for the compatibility with a reproduction-only standard. [0037] The present invention provides a method and apparatus for recording track information applicable to a new high-density optical disc. The invention records session information within the track information without any allocation of an additional physical area. In addition, the invention does not limit the number of used open tracks and supports the maximum sixteen tracks. Therefore, compared to the related art in which the maximum two open tracks (in case of the DVD-R, “RZone”) exist, this invention utilizes the disc more efficiently and provides an optimum structure of the track information suitable for such disc management. [0038] FIG. 2 illustrates different types of tracks on a write-once optical disc such as a BD-WO, which are applicable to the present invention. As shown, the disc is divided into a plurality of tracks. In this example, each of Tracks #1 and #2 is an “open track” in which an additionally recordable area remains in the track. Each of Tracks #3 and #4 is a “closed track” or a “complete track” in which an additional recording is impossible because the track is fully filled. The last track, Track #5, is an “intermediate track” in which an additional recording is always possible. [0039] The closed tracks, Tracks #3 and #4, in which additional recording is impossible, begin as open tracks. As any remaining available area of Tracks #3 and #4 is zero-padded due to a specific command (e.g., a close command from the host), the status of the tracks is changed into the closed tracks after the zero padding (hatched portion). In this example, the remaining available area of Track #3 is zero-padded before the track is closed. In some cases, when an open track is changed into a closed track according to a close command, it is possible to change only the information on the type of the track without the zero padding. [0040] Each track includes a “start PSN of track” and also includes always a “Last Recorded Address” (LRA) without regard to the type of the track. The PSN is a physical sector number and is a general term indicating information on a specific location of the disc. In addition, the LRA is the last address in which data is actually recorded. Therefore, in case of Track #3, the location just before the zero padding becomes the LRA (LRA3). In more detail, in case a recording-unit is a cluster, e.g., in a BD-WO, a total of 32 sectors exist in one cluster. In this case, if data is recorded on some sectors within one cluster and the remaining sectors are zero padded, the location prior to the zero padding becomes the LRA. [0041] Further, a next writable address (NWA) calculated from the LRA is determined only at the open tracks (Tracks #1 and #2) and the intermediate track (Track #5) by a request of the host or the like and then the calculated NWA information is transmitted appropriately, e.g., to the host. Since additional recording is impossible at the closed tracks (Tracks #3 and #4), there is no NWA for Tracks #3 and #4 in this example. [0042] The present invention provides schemes of indicating various types of tracks as shown in FIG. 2 and indicating session information associated with the tracks. This will be explained by referring to FIGS. 3-6. [0043] FIG. 3 illustrates the structure of a write-once optical disc such as a BD-WO and a method of recording management information on the disc according to various embodiments of the present invention. The write-once optical disc of FIG. 3 relates to a single layer disc having only one recording layer. However, the present invention is not limited to such and the disc structures and methods of the present invention are equally applicable to a multi-layer disc such as a dual layer disc. [0044] As shown in FIG. 3, the disc includes a lead-in area, a data area and a lead-out area. Inner and outer spare areas ISA0 and OSA0 for replacing defective areas in order to manage physical defects are provided in the data area. Defect management areas DMA1˜DMA4 are provided in the lead-in and lead-out areas. A first temporary defect management area TDMA1 is provided in the lead-in area, and a second temporary defect management area TDMA2 is provided in the outer spare area OSAO. The TDMAs store defect management information temporarily, while the DMAs store the defect management information permanently. When the data area cannot be recorded any more or the disc is to be finalized, the information stored in the final TDMA is transferred to at least one DMA. Generally, each DMA stores the same information so that if one DMA fails or has defects, important management information is not lost and can be retrieved from the other DMAs. In general, in case of a rewritable optical disc, only a defect management area (DMA) of a limited size is provided because it is possible to repeatedly write/erase data to/from the DMA. Thus, the DMA of a larger size is not needed. However, in case of the write-once optical disc such as a BD-WO, an area where the data are recorded once cannot be used for rewriting. Therefore, for a write-once optical disc, a DMA of a larger size is needed for the defect management. [0045] The TDMA1 is allocated with a fixed size in the lead-in area and the TDMA2 is allocated with a size varying according to the size of the outer spare area OSAO. For example, if the size of the OSAO is (N�256) clusters where N is a positive integer, then the size (P) of the OSAO can be:
[0046] A temporary defect list information (TDFL) and a temporary disc definition structure information (TDDS) together can be recorded on each TDMA as one recording-unit (in case of the DB-WO, one cluster). Track information (Track-Info) of the disc and the TDDS can be also recorded together as one recording-unit. The TDMA can have one or more of such recording-units. [0047] Here, if a defect occurs within the data area, a process of replacing the defective area with the spare area is carried out, and the management information associated with this process is stored as the TDFL. In case of a single layer disc, the TDFL is recorded with the size of 1 cluster to 3 clusters according to the size of the defect list. [0048] Track-Info (or SRRI) is disc status information that indicates whether or not a specific area of the disc has been recorded. Specifically, Track-Info can be used to cases where the disc has a sequential or incremental recording. As shown in FIG. 3, one cluster of the TDMA can include Track-Info at Sectors 0-30, and a TDDS at Sector 31. But it is also possible to record the TDDS at the first sector (Sector 0) and to record Track-Info at the remaining sectors of the cluster. [0049] The structure of the track information (Track-Info) 30 in FIG. 3 will be now described in detail. First, the track information 30 generally includes three parts: (a) a header (31) for making the track information identifiable, (b) a list of track information (32) for directly indicating the track information, and (c) a track information list terminator (33) for indicating the termination of the track information. [0050] The header (“Track Info Header”) 31 is located at the head of the Track-Info 30 and includes a “Track Info structure Identifier” field 31 a for making the track information identifiable, a “Location info of open track” field 31 b for indicating a location of the open track(s) existing within the corresponding track information, a “Total number of sessions” field 31 c for indicating the total number of sessions, and a “Location info of session start (or end) track” field 31 d for indicating a location of the start or end track of the session(s). Therefore, it is possible to check the contents of the overall track information before the track information list is directly read out. As a result, it is possible to newly define and standardize necessary information in the header, except for the above fields. [0051] The list of track information (“List of Track Info”) 32 is recorded next to the header 31. If the list of track information is terminated, the track information list terminator (“Track Info List Terminator”) 33 indicates the termination of the track information. Specifically, the track information list terminator is a meaningful information indicating the termination location of the corresponding track information in case the track information is variable in size. For example, the track information of the present invention can be recorded within the maximum thirty-one sectors of a cluster (the TDDS is recorded at the remaining one sector of the cluster). However, in case the track information need not be recorded in the entire thirty-one sectors at a specific time (specifically, at an initial recording), necessary track information is recorded and the type of the track information is then represented through the track information list terminator 33. Therefore, any system confusion can be prevented and, if necessary, other useful management information can be recorded to the spare area(s). [0052] Accordingly, as the management information of the disc, the track information (SRR information) 30 includes the header 31, the list of track information (SRR entry list) 32 and the track information list terminator 33, and all these pieces of information are recorded collectively at every updating. Other information, as needed, can be recorded as part of the track information 30. [0053] The list of track information 32 will be described below in more detail. [0054] The list of track information (SRR entry list) 32 includes a plurality of entries 34, each entry corresponding to one track (one SRR) within the disc and assigned to 8 bytes. This entry 34 is also referred to herein as a track information entry or an SRR entry. Each track information entry 34 includes a first status area/field (Status1) 35, a first location area/field 36 for carrying first address information of the corresponding track, a second status area/field (Status2) 37, and a second location area/field 38 for carrying last address information in which data is recorded on the corresponding track. The first location field 36 carries the start PSN of the corresponding track, and the second location field 38 carries the LRA of the corresponding track. [0055] As an example, bits b63˜b60 are allocated to the first status field 35, bits b59˜b32 are allocated to the first location field 36, bits b31˜b28 are allocated to be the second status field 37, and bits b27˜b0 are allocated to the second location field 38. Depending upon the need and standardization, the present invention covers different sizes and other ways of allocation for these fields of entries 34. [0056] The first and/or second status fields 35 and 37 carry status information including, but not limited to, the type of the corresponding track (track or SRR status) and session information relating to a session of the disc. As a result, the type of the corresponding track can be determined from the status information. The session information is information representing the location of a session where the corresponding track is located. In addition, the location of the corresponding track can be determined from the location fields 36 and 38. [0057] Accordingly, the system can check whether the specific area of the disc is a recordable area or a session closed area by accessing the track information entries. If a track information entry 34 is read out, the type of the corresponding track, the start location and the LRA of the track can be determined and/or verified accurately. Further, the session information within the track can be acquired. [0058] In this manner, the session information as well as the information on the types of the tracks are recorded together. Therefore, unlike the related art, the session information that the host or the user can utilize is represented without allocating an additional physical area on the disc, thereby improving greatly the efficiency of the disc use. The recording of the session information without any allocation of the physical area can be named as a “virtual session” or “session logical information”. [0059] FIG. 4 illustrates an example of the structure of a track information entry 34 within the track information of a write-once optical disc such as a BD-WO according to a first embodiment of the present invention. Referring to FIG. 4, in this example, a plurality of tracks (Tracks #1 to #8) exist on the disc. Each track is distinguished from each other by the track status information in the first status field (Status1) 35 that indicates the type of the corresponding track according to definitions. In addition, the second status field (Status2) 37 stores therein session status information indicating whether or not the corresponding track is the start of a session. That is, information indicating the location of a start of a session associated with the track is recorded as the session status information in the Status2. [0060] As an example, the track status information in the Status1 can be represented with “0000b” to indicate an open track, “0001b” to indicate an intermediate track, and “0010b” to indicate a closed track. Each session status information in the Status2 is distinguished from each other by allocating “1000b” to the respective session start tracks, and “0000b” to non-session start tracks, respectively. In FIG. 4, each of Sessions #1, #2 and #3 can be defined as the closed session that starts and ends with the closed track. Session #4 can be defined as the open session that starts with the open track (Track #7) and is not closed yet. According to the above definition, the recording on the closed session is impossible and only the reproduction of the corresponding session is possible. Further, the open session will be a recordable session. [0061] If a close session command to close a specific session is issued, the open tracks existing within the open sessions are all changed into the closed tracks and the information on the type of the tracks is also changed to indicate the closed status of the tracks. For example, although Track #2 of Session #1 is an open track at first, the zero padding (dummy padding) is applied to the recordable area of this track by the close command (e.g., a close track command or a close session command), thereby changing Track #2 into a closed track. As a result, Session #1 is changed from an open session to a closed session that ends with the closed track, Track #2. In a specific system, only the track status information on the type of the tracks can be changed into “0010b” to indicate a closed track without the zero padding applied to the track. [0062] In the example of FIG. 4, since all of Tracks #1 to #6 are closed tracks, their track status information in the Status1 indicates “0010b”. However, Tracks #1, #3 and #4 among them are respectively the start tracks of Sessions #1, #2 and #3, respectively, and as such, their session status information in the Status2 indicates “1000b”. Tracks #2, #5 and #6 are non-session start tracks, so that their session status information in the Status2 indicates “0000b”. Since Track #7 is an open track, its track status information in the Status1 indicates “0000b”. Track #7 is also the start track of Session #4, so that its session status information is “1000b”. Since Track #8 is an intermediate track, its track status information in the Status1 indicates “0001b”. In addition, since Track #8 is not the start track of a session, its session status information in the Status2 indicates “0000b”. In this case, Session #4 that is not closed can be defined as the open session. [0063] In the embodiment of FIG. 4, the session status information stored in the Status2 37 can be indicated with a single bit. For instance, a bit having a value “1” can mean a session start track, and a bit value “0” can mean a non session-start track, or vice versa. This one bit can be any bit allocated to the second status field 37. Similarly, any two adjacent bits can be allocated to indicate the track status information in the first status field 35. [0064] FIG. 5 illustrates an example of the structure of a track information entry 34 within the track information 30 of a write-once optical disc such as a BD-WO according to a second embodiment of the present invention. While the first embodiment in FIG. 4 distinguishes the respective tracks using only their start tracks, the second embodiment provides a method for variously distinguishing the tracks with the indications of a session start track, a session end track, a one track-one session, and a non-session start/end track. According to the second embodiment, the session status information recorded within the track information of the present invention can be defined in various manners. In addition, if the session information is needed as standardized information, the session information can be distinguished through its subdivision. [0065] The structure and use of the track information entry 34 in FIG. 5 is identical to those shown in FIG. 4 as discussed above, except for the second status field 37. In the second embodiment, the second status field (Status2) 37 stores session status information that can indicate four different statuses of the corresponding track associated with the entry 34. Accordingly, the structure and use of the second status field 37 will now be provided and the discussion of the identical parts will be omitted. [0066] Referring to FIG. 5, Tracks #1, #4 and #7 are respectively the start tracks of Sessions #1, #3 and #4 and thus, their session status information in the Status2 37 indicates “1000b”. Tracks #2 and #6 are respectively the session end tracks of Sessions #1 and #3, so that their session status information in the Status2 37 indicates “1001b”. Track #3 is the session start/end track so that its session status information in the Status2 37 is “0001b”. This means one track-one session (one track for one session) so that the one track is both the start and end track. Tracks #5 and #8 are middle tracks (non-session start/end tracks), so that their session status information in the Status2 37 indicates “0000b”. Accordingly, in case that each session ends with the closed track, it can be defined as the closed sessions (e.g., Sessions #1, #2 and #3). In case each session does not end with the close track or does not have the session end track, it can be defined as the open session (e.g., Session #4). [0067] In the embodiment of FIG. 5, a different number of bits can be allocated to indicate the session status information stored in the Status2 37. Similarly, any two adjacent bits can be allocated to indicate the track status information in the first status field 35. [0068] FIG. 6 illustrates an example of the structure of a track information entry 34 within the track information 30 of a write-once optical disc such as a BD-WO according to a third embodiment of the present invention. The structure and use of the track information entry 34 in FIG. 6 is identical to those shown in FIG. 4 as discussed above, except for the structure and use of the first and second fields 35 and 37. The structure and use of other fields 36 and 38 are identical to those of FIG. 4. [0069] In the embodiment of FIG. 6, the first status field (Status1) 35 is reserved and the second status field (Status2) 37 stores therein the session status information. The session status information can be indicated with a single bit. For instance, in the Status2, a bit having a value “1” can mean a session start track and a bit value “0” can mean a non session-start track. Any single bit of the Status2 can carry this session status information. For instance, the first bit (b31) of the Status2 37 can carry the session status information. Any unused bits of the Status2 can be reserved for any other use. [0070] In another variation, the Status2 in FIG. 6 can store therein both the session status information and the track status information, and the Status1 can be reserved for any other use. In this case, as an example, the first bit (b31) of the Status2 can carry the session status information, and the remaining three bits (b30-b28) of the Status2 can carry the track status information as discussed above in FIG. 4. [0071] FIG. 7 illustrates a method for updating the track information of the write-once disc of FIGS. 3-6 according to an embodiment of the present invention. [0072] Here, since the write-once optical disc has a special characteristic of one-time recording, the status information indicating the recorded status of a specific area in the disc is always necessary. Therefore, the “updating of the track information” means the system or the user is allowed to use the track information by updating the track information each time the disc status is changed according to the recording on the disc. [0073] Accordingly, when a new track is created or an existing track is closed, new track information is created so that the updating of the track information is necessary and performed. In addition, when the disc is ejected or the power is turned off, the use of the disc is paused. Therefore, in this case, the updating of the track information is also necessary and performed since the track information of a final status must be updated in order to accurately check the recorded status of the disc in the next use of the disc. [0074] According to the method of FIG. 7, the track information of a previous stage and the current track information to be updated are cumulatively recorded together, and a list of track information is sorted and recorded in a specific sequence on the disc. Specifically, in order to record an (n+1)-th track information during the updating process, a previously recorded (n)-th track information is first checked. Then, the (n)-th recorded track information and the current (n+1)-th track information are considered as one list of the track information, such that they are sorted and recorded in a specific sequence. In the same manner, in order to record an (n+2)-th track information to be updated, the previously recorded (n+1)-th track information is first checked. Then, the recorded (n+1)-th track information and the current (n+2)-th track information to be updated are considered as one list of the track information, so that they are sorted and recorded in a desired sequence. [0075] As an example only, the sorting can be according to the track status information indicating the type of the track, and then further based on the first address information (Start PSN) of the track. Other sorting schemes are possible. [0076] Herein, in case the sorting of the list of the track information according to the above example is applied to the present invention, the sorted status at the (n+2)-th updating is now discussed. First, the open track whose information on the type of the track is “0000b” is sorted. Next, only one intermediate track whose information on the type of the track is “0001b” is sorted and the general closed track whose information on the type of the track is “0010b” is sorted. In case the type of one track is equal to the type of the comparing track, the track whose first address information of the track is most leading is sorted preferentially. However, with regard to the sorting, a bit arrangement allocated as the information on the type of the track and a reference of the sorting are a matter of selection and a variety of methods can be applied according to the system or designer. [0077] The method of updating the track information according to the present invention, in which the sorting is performed including the previous track information, has an advantage in that all tracks existing within the disc are sorted according to the type of the tracks. Therefore, the desired information on the type of the tracks can be easily acquired. In addition, all track information of the previous stages can be checked at a time by referring to the latest track information updated last, thereby reducing the access time. [0078] FIG. 8 illustrates a recording/reproducing apparatus in which the present method of recording, managing and/or updating the disc status information of the disc as discussed above is implemented. The present methods and disc structures, however, can be implemented in other types of devices or systems. [0079] As shown in FIG. 8, the apparatus of the present invention includes a recording/reproducing part 10 for recording/reproducing information on/from an optical disc such as a write-once optical disc, e.g., BD-WO, and a control part 20 for controlling the recording/reproducing part 10. The control part 20 issues a command for recording or reproducing information on or from a specific area of the recording/reproducing part 10. Specifically, the recording/reproducing part 10 includes: an interface unit 12 for allowing communication with external devices such as the control part 20; a pickup unit 11 for recording or reproducing data on or from the optical disc; a data-processor 13 for receiving a reproduction signal from the pickup unit 11 to restore it into a desired signal value, or for modulating a to-be-recorded signal into a signal to be recorded on the optical disc; a servo unit 14 for accurately reading out the signal from the optical disc, or controlling the pickup unit 11 to accurately record the signal on the optical disc; a memory 15 for temporarily storing information, including the management information, and data; and a microprocessor 16 for controlling the components of the recording/reproducing part 10. All the elements of the recording/reproducing apparatus are operatively coupled. [0080] Herein, the recording/reproducing process of the optical disc according to the present invention will be described in detail. First, if an optical disc such as a BD-WO is loaded into the recording/reproducing apparatus of FIG. 8, the latest track information recorded on a preset management area of the optical disc is read out and temporarily stored in the memory 15 of the recording/reproducing part 10. The microprocessor 16 controls the recording and updating of the track information and other management information. In addition, since the latest used status of the disc is recorded within the track information of the disc, the start address information of the specific track, the LRA and the session information of the specific portion within the disc are read out, and the recording or non-recording status and the start/end of the session in the specific area can be checked from the read-out information. This information can then be used to record/reproduce data on/from the optical disc. [0081] In case it is necessary to record or reproduce information on or from the specific area of the optical disc, the control part 20 transmits this information as the recording/reproducing command to the recording/reproducing part 10 together with the location information of the specific area where the recording is desired. After the microprocessor 16 of the recording/reproducing part 10 receives the recording command, the control part 20 can accurately check the recorded status of the specific area within the disc, where the recording is desired, from the track information stored in the memory 15. Accordingly, it is possible to perform the recording/reproducing command desired by the control part 20 or any other device. [0082] According to the method of recording the management information on the write-once optical disc of the present invention, the track information can be recorded on the write-once optical disc in which the physical defect management is performed. In addition, because the session information is recorded within the track information of the disc, allocation of an additional physical area is not needed and the compatibility with the existing reproduction-only standard can be maintained. Further, using the disc structure and the sorting method of the present invention, it is possible to efficiently update the track information. As a result, it is possible to efficiently manage the management information even in the write-once optical disc having a new and different physical structure. [0083] It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
