Abstract
A recording method includes: generating a laser driving pulse, of which the number depends on a length of a mark which is formed, and where a pulse level of a pulse column at least in an intermediate pulse besides the lead pulse and the last pulse is sequentially decreased; performing laser emission, based on the laser driving pulse; and performing mark formation using thermal recording by laser irradiation on a recording medium.
Claims6
A recording method comprising:
- generating a laser driving pulse, of which the number depends on a length of a mark which is formed, and where a pulse level of a pulse column at least in an intermediate pulse besides the lead pulse and the last pulse is sequentially decreased;
