Patent ID: 7426166

Claim:
An information recording method of performing recording on an optical disk medium having a recording layer on which mark information is recorded by a laser beam emitted in accordance with a waveform based on a recording pulse sequence, said information recording method comprising the steps of: performing recording while varying a recording clock cycle T in accordance with a variation in a recording linear velocity such that a recording linear density becomes substantially constant; and when performing recording by using multiple pulses defined by an erase power Pe 1 and an erase power Pe 2 as an erasing pulse for forming a space part between mark parts, updating set values of the erase power Pe 1 and the erase power Pe 2 at predetermined intervals in accordance with the recording linear velocity such that the difference between the erase power Pe 1 and the erase power Pe 2 is increased in accordance with an increase in the recording linear velocity.
