摘要 |
There are problems that recording degradation happens, and an error occurs in reproduction unless appropriate recording pulse conditions are determined. A recording pulse controlling method according to the present invention is a recording pulse controlling method for adjusting recording pulses for recording information on a writable optical disc, which includes a mark length adjustment step and a mark position adjustment step. The mark length adjustment step is a step for adjusting a recording mark length adjustment parameter, and the recording mark length adjustment parameter is adjusted to have a value for forming a recording mark having a length closest to a predetermined recording mark length. The mark position adjustment step is a step for adjusting a recording mark position adjustment parameter after the mark length adjustment step, and the recording mark position adjustment parameter is adjusted to have a value for forming a recording mark at a position closest to a predetermined recording mark position.
