Patent ID: 7336580

Claim:
An optical recording method for recording data in an optical recording medium having a recording layer containing a phase change material at a plurality of linear recording velocities or a continuously changing linear recording velocity using a recording beam whose intensity is modulated in accordance with a recording waveform, the recording waveform including a direct current section having an intensity of Pbi and a recording pulse section for forming a record mark, the recording pulse section including at least three upward pulses, among which an upward pulse between a first upward pulse and a last upward pulse has an intensity of Pw, Pbi and Pw being set so as to satisfy PbiH/PbiL<1 and (PbiH/PwH)/(PbiL/PwL)<1 where PbiL and PwL are Pbi and Pw when data are to be recorded at a linear recording velocity V L selected from among the plurality of linear recording velocities or the continuously changing linear recording velocity and PbiH and PwH are Pbi and Pw when data are to be recorded at a linear recording velocity V H which satisfies 1.1≦V H /V L .
