ABSTRACT:
A laser-beam-scanned optical disc includes an information recording area and an information management area. The information management area stores recording management information having portions corresponding to respective integer multiples of a normal velocity relating to scanning of the disc. Each of the portions of the recording management information contains a first information piece representative of a recording strategy for recording of information on the information recording area and a second information piece representative of a recording laser power for recording of information on the information recording area.
