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.

摘要： An apparatus for recording information on a recordable optical disc (1) by applying a light beam on the surface thereof, the disc includes a first recording area on which information is recorded and reproduced while the disc is rotated at a first linear velocity (CLV₁); and a second recording area on which information is recorded and reproduced while the disc is rotated at a second linear velocity (CLV₂). The first recording area includes a test recording area. The apparatus includes recording power determining unit for determining first optimum recording power (P₁) for recording information on the first area by a test recording utilizing the test recording area, and for determining second optimum recording power (P₂) for recording information on the second area by multiplying the first optimum recording power by a predetermined constant (K).
