Patent ID: 7394743

Claim:
A laser-beam-scanned optical disc including an information recording area and an information management area, the information management area storing recording management information having first, second, and third portions corresponding to first, second, and third linear velocities relating to scanning of the disc respectively, wherein the first portion of the recording management information contains a first information piece representative of a recording strategy being a time-domain recording laser waveform for recording of information on the information recording area and a second information piece representative of a recording laser power for recording of information on the information recording area in connection with the first linear velocity, wherein the second portion of the recording management information contains a third information piece representative of a recording strategy being a time-domain recording laser waveform for recording of information on the information recording area and a fourth information piece representative of a recording laser power for recording of information on the information recording area in connection with the second linear velocity, and wherein the third portion of the recording management information contains a fifth information piece representative of a recording strategy being a time-domain recording laser waveform for recording of information on the information recording area and a sixth information piece representative of a recording laser power for recording of information on the information recording area in connection with the third linear velocity.
