OPTICAL DISK DEVICE AND RECORDING POWER DETERMINING METHOD

摘要

An object is to determine the optimum power with consideration for the recording state of a base layer track when determining the optimum power by test recording before recording user data. After recording at a second recording power higher by a specific amount than a first recording power, recording is done at a third recording power lower by a specific amount than the first recording power, and the first recording power is set to the recording power for data recording when a specified playback signal quality is achieved. <IMAGE>
