ABSTRACT:
A plurality type of adjustment data groups are stored in a memory for each of a plurality of adjustment items for adjusting a record signal waveform. The adjustment data group for each adjustment item is selected in accordance with identification information preset in accordance with a disk type and a record velocity magnification factor. The selected adjustment data groups are combined to form a record strategy. The record signal waveform is adjusted in accordance with the formed record strategy to record the record signal in an optical disk. It is possible to reduce the amount of adjustment data for the record signal waveform to be stored in the memory.
