Patent ID: 8411545

Claim:
A recording apparatus comprising: a rotation driving portion that rotates and drives an optical disc master; and a recording portion that performs an information recording on the optical disc master, by performing a laser beam irradiation on the optical disc master, based on a recording waveform which has a land pulse of a first power, a recording waveform portion having a recording pulse of a second power higher than the first power, and a cooling pulse which has a third power lower than the first power and is inserted between the land pulse and the recording waveform portion, in which, when performing the recording on the optical disc master at a second speed higher than a first speed, compared to a case of performing the recording at the first speed, the recording portion does not change the length of a waveform portion including the recording waveform portion and the cooling pulse placed at both ends of the recording waveform portion and the length of the land pulse, reduces the length of the cooling pulse of a front side of the cooling pulse and expands the length of the cooling pulse of a back side thereof, thereby performing the recording on the optical disc master.
