Patent ID: 7369470

Claim:
An optical recording medium allowing data to be recorded thereon and/or reproduced therefrom, comprising: erase pattern information for use to select an optimum erase power for erasing data from the optical recording medium, the erase pattern information including information regarding a power level of a first pulse of an 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 write pulses, 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 write pulses, wherein the erase pattern further includes a multi-pulse having a first level and a second level, and wherein the erase pattern information further indicates the power level of the first pulse of the erase pattern as one of the first level and the second level of the multi-pulse, and the power level of the period between the end of the erase pattern and the start point of the first pulse of the write pulses as one of the first level and the second level of the multi-pulse.
