ABSTRACT:
An optical disk recording method comprising steps of a) performing recording onto the optical disk with a ZCLV method by using zone parameter storage means for storing at least one zone division time and CLV of each zone in a track formed on the optical disk, as zone parameters, for each of a plurality of recording modes and optical disk type determination means for determining the type of the optical disk before recording; b) performing optimization of the recording velocity by detecting, before recording, servo signal fluctuation by accessing the optical disk, by determining maximum recording velocity defined by the speed of a rotational motor rotating the optical disk, and by calculating a changing point of the recording velocity; and c) limiting the speed of the rotational motor, when the servo signal fluctuation at the surface of the optical disk exceeds a reference level and determining the relation between the zone division time and the CLV of each zone.
