摘要:
An optical recording medium has a multi-layer structure recording layer structure recording layer portion including plural recording layers provided with tracks for guiding a recording light and being adapted to record data, where recording condition information and recording layer identification information for the recording layers are recorded on the tracks as information signals. Test writing is conducted on a recording layer that is subject to recording to derive a suitable recording condition based on recording condition information that is recorded on the recording layer, and direct recording is conducted according to a direct recording condition.
