Recordable optical disk and recording apparatus therefor.

摘要

A recordable optical disc (20) on which information is recorded by applying a light beam on the surface thereof, includes: a first recording area (22 - 25) on which information is recorded and reproduced while the disc is rotated at a first linear velocity; and a second recording area (26- 28) on which information is recorded and reproduced while the disc is rotated at a second linear velocity. Each of the first recording area and the second recording area includes a test recording area (22, 26) for use in determining optimum recording power of the light beam for recording information in the recording area, respectively. <IMAGE>
