OPTICAL RECORDING MEDIUM AND RECORDING / REPRODUCTION METHOD AND APPARATUS THEREFOR

摘要

An optical recording medium has a recording / reproduction conditions recording area for recording recording / reproduction conditions and recording / reproduction apparatus information identifying the recording / reproduction apparatus using the recording / reproduction conditions. When the optical recording medium is accessed in a recording / reproduction apparatus, the recording / reproduction conditions for the recording / reproduction apparatus are used. Therefore, recording or reproduction can be performed with use of optimum recording / reproduction apparatus appropriate for the optical recording medium and for the recording / reproduction apparatus. When the optical recording medium is used for the first time, test recording is performed by using a test recording region provided in the optical recording medium, and the obtained recording / reproduction conditions are recorded.
