Patent ID: 7727706

Claim:
A recording method for a dye-based recordable optical recording medium comprising: recording shortest marks on a recording layer containing a dye formed on a substrate having a guide groove by the use of one pulse beam, and recording second shortest marks or still longer marks at a pulse power as high as or lower than that of the shortest marks by the use of one pulse beam of which two sites of the front edge and the rear edge of pulse are highly energized for a given length of time, wherein a ratio Pc/W 4 (Pc represents the exposure dose of a cooling pulse beam applied on the rear edge of pulse, and W 4 represents the power of irradiation beams other than those engaged in formation of marks) during recording of each of marks at a recording linear velocity of 12 m/s or more is set from more than 1.0 to 3.0.
