Abstract:
An optical disc recording method of suppressing variations in the record quality due to variations in an initial strategy of a write strategy using many parameters corresponding to a next-generation large-capacity optical disc. Modulation conditions for recorded data on the optical disc are determined based on a real measurement thereof; an initial strategy that meets the modulation conditions is determined; an optical strategy is determined in which the record quality is best in the vicinity of the initial strategy; and data is recorded on the optical disc, using the optimal strategy.
