Patent ID: 7376064

Claim:
A method of recording data on an optical recording medium, the method comprising: generating a recording waveform having an erase pattern comprising a multi-pulse having a high level and a low level; setting a power level of a first pulse of the erase pattern, and a power level of a period between an end of the erase pattern and a start point of a first pulse of a recording pattern, to the high level of the multi-pulse or the low level of the multi-pulse based on pulse information stored on the optical recording medium; and radiating a light onto the optical recording medium according to the generated recording waveform to form a mark or a space; wherein the pulse information stored on the optical recording medium comprises: power level information regarding the power level of the first pulse of the erase pattern, and the power level of the period between the end of the erase pattern and the start point of the first pulse of the recording pattern; and duration information regarding a duration of the period between the end of the erase pattern and the start point of the first pulse of the recording pattern.
