摘要： A data-arranging method similar to that of a RAM disk is adopted for a ROM disk to make the ROM disk highly compatible with the RAM disk. According to this method, buffer areas are allocated as a data run-in and a data run-out respectively preceding and succeeding a RUB (Recording Unit Block) used as a recording/reproduction unit. In addition, at locations separated from each other in the buffer areas by a distance equal in length to a sync-data gap in successive frames in the RUB, pieces of sync data (SA) are provided so that the sync data always appears at equal intervals in a signal reproduced from the ROM disk, providing a feature advantageous to establishment and protection of synchronization. It is thus possible to implement a ROM disk that is highly compatible with the RAM disk and advantageous to a synchronization system.

摘要： The present invention is directed to a data recordable optical disc (2), wherein buffer areas for random access (Data Run-in DRi, Data Run-out DRo) for random access are respectively disposed before and after respective blocks (BLK, BLK1, BLK2), whereby when recording of new block is started, the block is recorded in the state where respective buffer areas overlap with each other with respect to new block and existing block so that no gap takes place. Signal patterns for Phase Locked Loop (PLL) at the time of data reproduction, Auto Gain Control (AGC), and automatic adjustment of light source power, synchronization pattern, and/or signal patterns used for generation of reproduction clock, and detection of block reproduction end, etc. are recorded within the buffer area.
