Definitions
- the present invention relates to a write-once information recording medium capable of recording data only once in the same area, an information recording method, an information reproducing method, an information recording device, and an information reproducing device.
- An optical disk is an information recording medium having a sector structure.
- AV data such as audio and video has been digitized, and higher density and larger capacity optical discs have been developed.
- Optical discs can be broadly classified into three types according to their characteristics.
- One is a read-only disc in which data is recorded by the unevenness of the disc, and the user cannot record new data.
- Second, it is a write-once disc that can be recorded only once by providing an organic dye or the like as a recording film.
- a rewritable disc that can be recorded (rewritable) multiple times by providing a recording film with a phase change material or the like.
- write-once discs have become very popular in recent years because of their high compatibility with read-only discs and the fact that they can be manufactured relatively inexpensively for reasons of manufacturing facilities.
- DVD-R DigitAlveSasti1eDiscRecordable
- CD-R CompactRetDirecReordable
- write-once discs require not only the recorded data but also their management information to be rewritten, so the unique control of write-once discs is required.
- description will be made using an example of a DVD-R disc.
- 1A to 1C are explanatory diagrams for explaining a case where data is added to a DVD-R disc a plurality of times.
- FIG. 1A shows a data structure of a DVD-R disc 100 in which a user data area 102 for recording data specified by a user is in an unrecorded state.
- An RMA (RecoordIngManagementArea) located on the inner periphery is an area for managing the recording state of the user data area 102.
- RZone (ReservedZone).
- RZone # 1 is the only one recordable area.
- FIG. 1B shows a state where three additional recordable areas RZone # 1, RZone # 2, and RZone # 3 are secured.
- the shaded area indicates the area that has already been recorded.
- the RMA 101 manages a start address of each RZone and an LRA (LastRecoordDeads) indicating the last recording position in each RZone. To enable the disc of FIG.
- a border close process is required. This is done to avoid the restriction that the read-only device cannot access the unrecorded area on the disc.
- FIG. 1C shows the data structure after border close processing. Data is recorded so that there is no unrecorded area in RZ one, and a border area (B out) area 110 is recorded at the end of the border area. This area prevents a read-only device from accidentally accessing an unrecorded area. After the border area # 1 area recorded as described above, an area RZ one # 4 usable for the next recording is generated.
- FIG. 2 shows the data structure of RMA 101.
- the RMA 101 is an area for storing an RMD (RecordIngManagementDescriptor) that manages RZone information.
- the RMD is updated when a new RZone is reserved or when the disc is ejected from the recording device. Since the new RMD is updated to the subsequent area, the latest RMD 120 is recorded at the end of the recorded area (immediately before the unrecorded area).
- the latest RMD 120 includes disc identification information 121 for identifying the disc type, OP C (Optimum Power C a 1 ibration) information 122 for storing adjustment results such as recording power, and management information on borders. It includes border management information 123 to be stored and RZ one management information 124 to store management information on RZ one.
- the RZ one management information 124 stores information about each RZ one.
- the last RZ one number 125 stores the last RZ one number secured on the disk, so 3 indicating RZ one # 3 is stored.
- Reserved RZ one # 1 number 126 stores 1 indicating reserved RZ one # 1
- reserved RZ one # 2 number 127 stores 2 indicating reserved RZ one # 2.
- unclosed reservations RZ one is limited to a maximum of two.
- the RZ one # 1 start address 128 stores an address indicating the start position of the RZ one # 1 area.
- RZ one # 1 LRA 129 stores an address indicating the final position of the recorded area of RZ one # 1.
- FIG. 3 is a flowchart showing processing when a DVD-R disc, which is a conventional write-once information recording medium, is mounted on a recording device. Hereinafter, the contents of the processing will be described along the flow.
- the recording device determines that the mounted information recording medium is a DVD-R disc
- the recording device searches the end of the recorded area of the RMA area to obtain the latest RMD.
- the recording device sequentially determines whether the area is a recorded area or an unrecorded area based on a reproduction signal from a disc or the like, and searches for a boundary between the recorded area and the unrecorded area (S301).
- the recording apparatus determines that the last area of the recorded area is the latest RMD and executes a read process (S302). Based on the contents of the latest RMD area read from the disk, it is determined whether or not there is a reservation RZone that can be added to the contents of the latest RMD. If a recordable reservation RZone is detected, the process proceeds to (S304), and if no recordable reservation RZone is detected, the process proceeds to (S305) (S303).
- the recording device searches a subsequent area from the LRA of the reservation RZone.
- the LRA since the LRA may not be the true final recorded position as described above, the purpose is to acquire the true final recorded position by searching the subsequent area.
- the recording device internally stores, as a true LRA, the address of the area immediately before the boundary between the recorded area and the unrecorded area that was first detected in the area subsequent to the LRA. After that, the process proceeds to (S303) to determine whether or not there is any other additionally recordable reservation RZone (S304) (S304).
- the recording device that has completed the LRA search for all the reserved RZones finally performs the LRA search processing for the final RZone.
- the boundary between the recorded area and the unrecorded area is searched for in the same way as the processing in (S304), and the true LRA is detected and stored internally (S304). 305).
- the recording apparatus can write all the recordable ad- dresses on the disc. And store it inside the device.
- FIG. 4 is a flowchart showing a process of newly reserving an RZone for managing an additional writing position.
- an RZone reservation instruction and an area length of the RZone to be reserved have been received from a higher-level control means such as a personal computer.
- the recording device that has received the new RZone reservation instruction determines whether or not a predetermined number of reservable RZones (up to two for DVD-R discs) is not exceeded. If it is determined that reserving a new RZone exceeds the number of RZone that can be reserved, an error is terminated. If it is determined that the number of RZones that can be reserved even if a new RZone is reserved does not exceed the number of RZones that can be reserved, the process proceeds to (S402) and the reservation processing of the RZone is continued (S401).
- the recording apparatus secures the area length of RZone specified by the higher-level control means in the first part of the final RZone. Also, the start position of the last RZone is updated so that it follows the area newly reserved as the reserved RZone.
- the recording device stores the newly reserved start address LRA of the RZone in the RMD information read from the disk and stored therein, and updates the start address of the final RZone (S402).
- the recording device records the RMD updated in (S402) in the head area of the unrecorded area in the RMA, that is, the area immediately after the latest RMD (S403).
- the recording device updates the contents of the RMD when receiving a new RZone reservation instruction.
- FIG. 5 is a flowchart showing a recording procedure for recording user data in the user data area 102 of the DVD-R disc described with reference to FIGS. 1A to 1C and 2.
- the control means of the upper such as a personal Combi Yuta
- the recording start Adoresu for recording user data as the control information c
- the recording device refers to the RMD information held internally, and the recording start address specified by the higher-level control means matches any of the recordable reserved RZ one or the last RZ one recordable address. It is determined whether or not to do.
- the appendable address means an address in an area immediately after the address already recorded. If the recording start address specified by the higher-level control means does not match any of the recordable addresses of the recordable RZ one, the processing ends as an error end. On the other hand, if the address matches any of the additionally recordable addresses of the RZ one that can be additionally recorded, the process proceeds to (S502) (S501).
- the recording device refers to the RMD information held internally and determines whether or not the recordable area for the specified recording length remains in the recordable RZ one that requires recording. I do. If there is a recordable area longer than the specified recording length, the process proceeds to (S503), and if there is no recordable area of the specified recording length, the process ends with an error (S502).
- the recording device receives the user data to be recorded from the higher-level control means, and records the user data transferred from the designated recording start address to the subsequent area (S503, S504).
- the recording device updates the RMD information stored in the internal memory of the device. What is updated here is the last recorded address (LRA) of the RZone where the user data was recorded (S506).
- LRA last recorded address
- the recording device performs recording in the area subsequent to the recordable position and updates the last recorded address of the recorded RZ one.
- the updated RMD information may be recorded on a disc.
- RMD information to be stored in the device at the time of ejection of the disc is recorded on the disc for reasons of performance due to the time required for recording and for suppressing consumption of the RMA area. You.
- FIG. 6 is a flowchart showing a processing procedure for closing the RZone of the DVD-R disc described in FIGS. 1A to 1C and FIG.
- a close instruction command and an RZone number to be closed are transmitted as control information from an upper control means such as a personal computer.
- the recording device Upon receiving the RZone close instruction from the higher-level control means, the recording device determines whether the specified RZone is in a recordable state. If it is determined that the additional recording is possible, the process proceeds to the processing step (S602), and the closing process is continued. If it is determined that it is not in the recordable state, the close processing ends with an error (S60 The recording device refers to the RMD information stored in the device, and receives the close instruction from the higher-level control means, the RZ one number. If the close instruction is determined to be the reserved RZ one, the process proceeds to the processing step (S603), and the final RZ one is determined. In this case, the processing step (S602) shifts to the processing step (S605).
- the recording device determines whether an unrecorded area exists in the RZone specified to be closed. If an unrecorded area exists, the process proceeds to a processing step (S604). If no unrecorded area exists, the process proceeds to a processing step (S605) (S603).
- Deleting RZone here means that if the closed RZone is a reserved RZone, 0 is set in the reserved RZone number area in the RZone management information. If the closed RZone is the final RZone, set the final RZone number area to a value obtained by adding one. For example, in FIG. 2, when the reservation RZone # 1 is closed, the reservation RZone # 1 number 126 is set to 0. As another example, if 3 is stored in the last RZone number 125, and the RZone number 3 is closed, the last RZone number 125 is set to 4.
- the closed RZone information is deleted from the RMD (S605).
- the recording device records the RMD updated in (S605) in the unrecorded area head area in the RMA on the disk, that is, the area immediately after the latest RMD (S606). As described above, the recording device performs the closing process of the RZone so that no unrecorded area remains in the RZone.

- the CPU 514 branches to a processing step (S1507) to shift to the user data recording process. If the recording process has failed, the process branches to a processing step (S1506) (S1505).
- the CPU 514 When the update of the recorded area position fails, the CPU 514 resets the succeeding area of the area where the recording failed as the recording target position in order to attempt recording in the area subsequent to the recorded area position storage area. If the loaded disc is a two-layer disc and the entire recorded area position storage area of the first layer is used, the top of the recorded area position storage area of the second layer is recorded. The target position is reset (S1506).

- the CPU 514 activates the user data recording process in the service circuit 509 and the ECC circuit 512, and receives the processing result after the recording process is completed (S1508).
- the CPU 514 determines the result of the received recording process, and if it determines that the recording has been completed normally, ends the process with normal termination. On the other hand, if it is determined that the recording has ended with an error, the processing ends with an error (S1509).
- the CPU 514 executes the processing step (S1501), so that before the user data is recorded in the user data area, the record of the user data is stored in at least one of the recorded data in the user data area. It functions as a judging means for judging whether or not to start from a predetermined position which is located backward from the end of the recorded area located rearmost in the user data area in the user data area.
- the CPU 514 executes the processing steps (S1502) to (S1509) so that the recording of the user data is performed at a predetermined distance away from the end of the recorded area located rearmost in the user data area. If it is determined to start from the position, the user data is recorded from the predetermined position, and the latest recorded area position indicating the position of the rearmost recorded area in the user data area is recorded.
