Abstract:
1. An optical disk recording method for performing recording of data on an optical disk by controlling an irradiation time (n+k)T of a writing optical beam to form a pit length corresponding to the data, where T: a time corresponding to a unit pit length; n: a multiple number (integer number) of the pit length to be formed relative to the unit pit length; and k: a correction quantity wherein the method comprises the steps of: recording data while varying a linear velocity multiplication factor of the optical disk; increasing a power of the writing optical beam as the linear velocity multiplication factor rises; changing a value of the correction quantity k in accordance with the linear velocity multiplication factor when the same is less than a predetermined critical linear velocity multiplication factor; and fixing a value of the correction quantity k when the linear velocity multiplication factor is not less than the predetermined critical linear velocity multiplication factor.
