ABSTRACT:
Congested rewriting in the same area is to be evaded to suppress the tendency towards occurrence of defective areas. When a stream1has been recorded, the last written address, representing the last written position, is stored. When recording a stream2next, recording is started directly following the position indicated by the last written address for the stream1. The last written address, corresponding to the last address of the recording position, is stored. If the stream2is erased for recording a stream3, recording is started not at a position directly following the last written address of the stream1, but from a position directly following the last written address of the stream2. When the stream3has reached the end of a recording area, the next following data is recorded as from a position directly following the stream1.
