Read-only recording medium, reproduction apparatus and reproduction method |
摘要 |
<p>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.</p> |
