摘要 |
Congested rewriting in the same area is to be evaded to suppress the tendency towards occurrence of defective areas. When a stream 1 has been recorded, the last written address, representing the last written position, is stored. When recording a stream 2 next, recording is started directly following the position indicated by the last written address for the stream 1 . The last written address, corresponding to the last address of the recording position, is stored. If the stream 2 is erased for recording a stream 3 , recording is started not at a position directly following the last written address of the stream 1 , but from a position directly following the last written address of the stream 2 . When the stream 3 has reached the end of a recording area, the next following data is recorded as from a position directly following the stream 1.
