A write-once recordable blu-ray disc (BD-WO) is also under development. Unlike a rewritable disc, data can only be recorded once in the entire area of a write-once optical disc; and data cannot be physically overwritten in the write-once optical disc. Nevertheless, there may occur instances, where it would be desirable to edit or partially modify recorded data. For example, for simplicity of use of the host or the user, the virtual overwriting of the data may be desirable.
In one embodiment, the recording medium includes a user data area on which one or more recording ranges are allocated and a management area. The method of recording on the recording medium includes receiving an overwriting command to record data on a recorded area of a recording range. Each recording range is one of an open recording range having a recordable position and a closed recording range not having a recordable position. An open recording range is selected for recording the data from the one or more open recording ranges on the user data area, and the data is recorded starting from the recordable position of the selected open recording range.
The present invention also relates to an apparatus for recording data on a recording medium.
In one embodiment, the recording medium includes a user data area on which one or more recording ranges are allocated and a management area. The apparatus for recording data on the recording medium includes a recording unit for recording the data on the recording medium, and a controller. The controller receives an overwriting command to record the data on a recorded area of a recording range. Each recording range is one of an open recording range having a recordable position and a closed recording range, which does not have a recordable position. The controller selects an open recording range for recording the data from one or more of the open recording ranges on the user data area, and controls the recording unit to record the data starting from the recordable position of the selected open recording range.
The present invention is also directed to a recording medium.
In one embodiment, the recording medium includes a user data area on which one or more recording ranges are allocated and a management area on which management information for the recording ranges is recorded. Each recording range is one of an open recording range having a recordable position and a closed recording range not having a recordable position. An open recording range for recording data is selected from one or more open recording ranges on the user data area if an overwriting command to record the data is made to a recorded area of a recording range on the user data area. The data is recorded starting from the recordable position of the selected open recording range.
The present invention is further related to a method of reproducing data recorded on a recording medium.
In one embodiment, the recording medium includes a user data on which one or more recording ranges are allocated, and a management area. The method of reproducing data recorded on the recording medium includes receiving a reproducing command to reproduce a first data recorded on an area of a first recording range. Each recording range is one or an open recording range having a recordable position and a closed recording range not having a recordable position. The method of reproducing data recorded on the recording medium also includes reproducing second data replacing the first data. The second data recorded in a second recording range is overwritten data of the first data. The relationship between the first and second range is managed by management information in the management area.
Still further, the present invention relates to an apparatus for reproducing data recorded on a recording medium.
In one embodiment, the recording medium includes a user data area on which one or more recording ranges are allocated and a management area. The apparatus for reproducing data recorded on the recording medium includes a reproducing unit and a controller. The reproducing unit reproduces the data from the recording medium. The controller receives a reproducing command to reproduce a first data recorded on an area of a first recording range. Each recording is one of an open recording range having a recordable position and a closed recording range not having a recordable position. The controller controls the reproducing unit to reproduce a second data replacing the first data.
FIG. 3 illustrates an example of logical overwriting being performed on an open sequential recording range (SRR) in a write-once optical disc according to an embodiment of the present invention;
FIG. 4 illustrates an example of logical overwriting being performed on a closed SRR in a write-once recordable optical disc according to an embodiment of the present invention;
FIG. 5 illustrates a next write address (NWA) selecting method during logical overwriting in a sequential recording mode (SRM) of a write-once optical disc according to an embodiment of the present invention;
FIG. 6 illustrates a sequential recording range information (SRRI) structure for a sequential recording mode according to an embodiment of the present invention;
FIG. 7 illustrates a logical overwriting method for a random recording mode (RRM) according to an embodiment of the present invention; and
FIG. 2 illustrates a logical overwriting method for a write-once high density optical disc according to an embodiment of the present invention. As shown, the write-once high density optical disc includes a lead-in area, a data zone, and a lead-out area. The data zone includes an inner spare area (ISA), an outer spare area (OSA), and a user data area. The lead-in area is used as an area for recording diverse management information for recording/reproducing data on/from the optical disc. The lead-in area may be provided with a temporary disc management area (TDMA), which is an area for recording defect management information and recording management information for the optical disc. A separate additional TDMA within a spare may also be allocated for defects that may frequently occur during the use of the optical disc and for updating the recording management information.
For example, as shown in FIG. 2, when a writing (or recording) command for data B of a recorded data A area within an SRR (SRR #n) is transmitted, the data B that is to be recorded in the data A area is either recorded at a next writable area, which is the NWA, of the SRR including the data A area or, alternatively, recorded in a spare area (e.g., the OSA). When the data is recorded in the NWA of the SRR including the data A area, a next writable area from the SRR (SRR #n) becomes NWA′. After performing the replacement recording of the data, as described above, information on the position of the area in which data was to be overwritten (i.e., data A area) and the replacement recorded area (i.e., the data B area of the user data area or the data B area of the spare area) is recorded in the TDMA as a LOW entry. The LOW entry is broadly categorized into two types: a Re-Allocated Defect (RAD) type and a Continuous Re-allocated Defect (CRD) type.
The LOW entry of the RAD type includes information on a logical overwriting performed in a single cluster. Each entry includes a first physical sector number (PSN) of a first cluster of the area in which logical overwriting is performed, and a first physical sector number (PSN) of a first cluster of the area in which replacement recording of the logical overwriting is performed. On the other hand, the LOW entry of the CRD type includes information on a logical overwriting performed in a plurality of consecutive clusters and, therefore, uses two entries. More specifically, one of the two entries includes a first PSN of a first cluster wherein logical overwriting is performed, and a first PSN of a first cluster wherein replacement recording of the logical overwriting is performed. The other entry includes a first PSN of a last cluster wherein logical overwriting is performed, and a first PSN of a last cluster wherein replacement recording of the logical overwriting is performed.
Therefore, when the optical disc logically overwritten, as described above, is reproduced in a later process, an optical disc drive refers to the entry information recorded in the TDMA and identifies the information of the logically overwritten area and the replacement recorded area, thereby being able to reproduce the replacement recorded data B area instead of the data A area. In the SRM type, it may be preferable to perform the replacement recording of the logical overwriting in the NWA of the user data area rather than the spare area. More specifically, in the recordable optical disc, the spare area is also used for replacement recording a defect area as a method of defect management. Therefore, when the spare area is to be used for the replacement recording of the logical overwriting, there lies a problem of having to ensure, in advance, a sufficient range of spare area, the usage of which is unclear, during the initialization of the optical disc. Thus, in order to avoid such problems, it may be preferable to perform replacement recording of the logical overwriting in the NWA of the user data area. When performing logical overwriting in the user data area using the SRM type, the logical overwriting can be performed when the SRR is open and when the SRR is closed.
FIG. 3 illustrates an example of logical overwriting being performed on an open SRR in a write-once optical disc according to an embodiment of the present invention. In the SRM, an open SRR refers to a non-recorded SRR or an SRR having some recordable area (i.e., unrecorded portion) remaining. Open SRRs have an NWA. A closed SRR refers to when a recordable area in an SRR no longer remains or exists, or to an SRR changed to a closed state, even though a unrecorded area or portion does exist, but is no longer allowed due to a request from the user or host. Therefore, an NWA does not exist for a closed SRR. Referring to FIG. 3, when an overwriting command for a recorded area is received for an open SRR, the replacement recording may be performed in any of the open SRRs. In other words, when a command for overwriting data B on a recorded data A area is received for an open SRR (SRR #n), the data B that is to be recorded on the data A area is either replacement recorded beginning at the NWA of the SRR including the data A area, or replacement recorded beginning at the NWA of any other open SRR.
FIG. 4 illustrates an example of logical overwriting being performed on a closed SRR in a write-once optical disc according to an embodiment of the present invention. Referring to FIG. 4, when the writing command given (or made) by the host is an overwriting command on a recorded area in a closed SRR, since the closed SRR does not include an NWA, the replacement recording is performed in an open SRR. At this point, when overwriting data on the recorded area of the closed SRR, the replacement recording may also be performed in a spare area. More specifically, the replacement recording is performed beginning at an NWA an open SRR or in a spare area such as the OSA. For a closed SRR, the replacement recording may be specifically performed in a spare area instead of the user data area.
As described above, the logical overwriting in a write-once high density optical disc in the SRM is performed at a NWA. In one embodiment, a maximum of 16 SRRs may be allocated, and a maximum of 16 NWAs may be included, accordingly. A method for selecting an NWA according to an embodiment of the present invention will now be described in detail with reference to FIG. 5.
FIG. 5 illustrates an NWA selecting method during logical overwriting in a sequential recording mode of a write-once optical disc according to an embodiment of the present invention. Referring to FIG. 5, a plurality of sequential recording ranges (SRRs) may be allocated in the user data area of the write-once high density optical disc. And, in this embodiment, a maximum of 16 SRRs may be allocated. Each of the open SRRs includes an NWA indicating a next writable area.
According to this embodiment, for the plurality of NWAs that may exist, when a writing command requests data to be overwritten on a recorded area, replacement recording is performed in the open SRR containing the data to be overwritten. More specifically, when an NWA exists within an SRR (SRR #n) to which a data overwriting command has been given (or made), replacement recording is performed at the NWA of this open SRR (SRR #n). If the SRRs to which the overwriting command has been given (or made) is unavailable, for example, if the open SRR has been changed (or modified) to closed SRR, the replacement recording is performed at a NWA of a neighboring SRR.
Therefore, when the SRR (SRR #n) to be over-written is a closed SRR, replacement recording is performed in a previous open SRR (SRR #n−1) or a next open SRR (SRR #n+1) of the SRR (SRR #n). Also, the SRR area may be unavailable because the unrecorded portion may be inadequate and insufficient for the replacement recording. In other words, the remaining recordable area of the SRR (SRR #n) or the neighboring SRR (SRR #n+1 or SRR #n−1), may be insufficient, and so replacement recording may not be performed at a single time.
In an embodiment of the present invention, when the remaining recordable area of the SRR or the neighboring SRRs is insufficient to perform replacement recording, the replacement recording is then performed in an open SRR nearest the SRR #n having sufficient recordable (or writable) area. When replacement recording of the data is performed as described above, continuity of the replacement recorded area may be ensured. Furthermore, waste in the re-allocated defect (RAD) entry or the continuous re-allocated defect (CRD) entry, in which the addresses of the overwriting area and the replacement recording area is recorded, can be prevented.
Meanwhile, in another embodiment of the present invention, when the remaining recordable area for the SRR or the neighboring SRR is insufficient to perform replacement recording, replacement recording may be performed in the insufficient area and replacement recording of the remaining data may be continued in a next neighboring open SRR. When using the above-described method, a plurality of RAD or CRD entries may exist in order to indicate replacement recording information of a logical overwriting. Furthermore, in yet another embodiment of the present invention, replacement recording of the logical overwriting is sequentially performed starting from the first open SRR. More specifically, regardless of which SRR the logical overwriting is associated, the replacement recording is performed starting from the first open SRR.
When the optical disc drive performs replacement recording on the neighboring SRR or starting from the first open SRR, the information on the first open SRR can be obtained by referring to sequential recording range information (SRRI) that is recorded in the TDMA. This will be described in detail with reference to FIG. 6. FIG. 6 illustrates an SRRI structure according to an embodiment of the present invention. Referring to FIG. 6, the SRRI recorded in the TDMA includes a �SRRI Header� field, a �List of SRR entries� field, and a �SRRI Terminator� field.
The �SRRI Header� field includes a �SRRI identifier=�SR�� field, a �number of SRR entries� field, a �number of Open SRRs� field, and a �List of Open SRR numbers� field. Herein, the number of SRR entries, which will be described in a later process, is recorded in the �number of SRR entries� field. The number of open SRRs is recorded in the �number of Open SRRs field�, and a number list of the open SRRs is recorded in the �List of Open SRR numbers� field. In the �List of SRR entries� field, a list of the Open SRR numbers is recorded. Herein, a number list of a maximum of 16 allocatable open SRRs is recorded. When the number of allocated open SRRs is lower than �16�, then �0� is recorded in an unused Open SRR field. The SRR numbers are aligned by a decreasing (or descending) order. Therefore, the optical disc drive refers to the �List of Open SRR numbers� field when performing logical overwriting so as to search and find a replacement recordable SRR. More specifically, referring to FIG. 6, when the logical overwriting is to be performed in a recorded area of a 9th SRR (SRR #9), the data may be replacement recorded on the 9th SRR, or replacement recording may be performed on a neighboring (Le., the closest) SRR, which is the 8th SRR or the 10th SRR, or replacement recording may be performed starting from the 1st SRR.
A list of SRR entries is recorded in the �List of SRR entries� field, of the SRRI. Herein, the SRR entries are sequentially allocated and recorded starting from �1�. At this point, 8 bytes are allocated in an SRR entry, wherein certain information is recorded. The SRR entry includes a �Start PSN of the SRR #n� field, a �Session start� field, and a �LRA in the SRR #n� field. More specifically, a physical sector number (PSN) of a starting position (or area) of SRR #n is allocated in the size of 28 bits and recorded in the �Start PSN of the SRR #n� field. The �Session start� field is the size of 1 bit, and a last recorded area (LRA) of SRR #n is recorded in the �LRA in the SRR #n� field, which has a size of 28 bits.
Thus, the optical disc drive can identify the position information of a recorded area of the corresponding SRR by using the information included in the SRR entry. The NWA indicating the next writable area may be determined by using the �LRA in the SRR #n� field information. Namely, by using the physical sector number (PSN) recorded in the �LRA in the SRR #n�, the first sector of the next cluster becomes the NWA. If �0� is already recorded in the �LRA in the SRR #n� field, this indicates that data is not recorded in SRR #n. Therefore, the sector recorded in the �Start PSN of the SRR #n� field becomes the NWA.
As described above, recording of data in the recordable high density optical disc can be broadly categorized into an SRM type and an RRM type. In the RRM type, the recording of data is performed randomly on all non-recorded clusters. In the above-described RRM type, information on the recorded status for the clusters in the user data area is reflected in a space bit map (SBM). More specifically, the SBM includes bits matching one-to-one with the clusters of the user data area so as to indicate the recording status of the corresponding area. The method for logical overwriting data in the RRM type will now be described with reference to FIG. 7.
FIG. 7 illustrates a logical overwriting method in an RRM type of recordable optical disc according to an embodiment of the present invention. Referring to FIG. 7, in the RRM type, when an overwriting command is transmitted from the host for overwriting data on a recorded area, the data that is intended to be recorded in the recorded area is replacement recorded in, for example, a spare area. Due to the characteristic of the RRM type, since the data is randomly recorded in the clusters in the user data area, performing replacement recording of the logical overwriting in the user data area may not beefficient. Therefore, in the RRM type, the data of the logical overwriting may be replacement recorded in the spare area such as the OSA. At this point, the spare area may also be used as a replacement area for a defect area, and so the size of the spare area may be sufficiently assigned and allocated during an initialization of the optical disc.
FIG. 8 illustrates a block diagram of an optical recording and reproducing apparatus according to the present invention. Referring to FIG. 8, the optical recording and/or reproducing apparatus includes a recording/reproducing device 10 for performing recording/reproduction on the optical disc, and a host, or controller 20 for controlling the recording/reproducing device 10. (Herein, the recording/reproducing device 10 is often referred to as an �optical disc drive�, and both terms will be used in the description of the present invention).
In the optical recording and/or reproducing apparatus, process steps of an embodiment of the method for recording data on the recordable optical disc will now be described. Upon inserting the recordable optical disc into the optical recording and/or reproducing apparatus, management information is read from the optical disc and stored in the memory 15 of the recording/reproducing device 10. Herein, if the user desires to write on a particular area of the optical disc, the host 20, which responds to a writing command indicating this desire, provides information on a desired writing position to the recording/reproducing device 10, along with a set of data that is to be written.
While performing writing of data as described above, when overwriting is to be performed in accordance with the user command, the data that is to be recorded (or written) on the overlapping (or overwriting) area is replacement recorded in another area within the data zone, such as the user data area or the spare area, as described above with respect to one of the embodiments of the present invention. Then, corresponding information including RAD and CRD entries that are created during this process are recorded in the TDMA within the lead-in area. For this, the microcomputer 16 provides the position information of the replacement recorded area and the data according to the command of the host to the servo unit 14 and the data-processor 13, so that the recording or replacement recording is completed at a desired position on the optical disc through the pickup unit 11.
As described above, the method and apparatus for overwriting data on the recordable high density optical disc according to the present invention has the following advantages. By providing an efficient method for overwriting data in accordance with a recording mode of the write-once high density optical disc, when overwriting data on a recorded area within the optical disc, the write-once high density optical disc can be more efficiently managed and reproduced.
