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.
