Disc player |
摘要 |
<p>In a disc player, a CAL pattern is recorded in a disc-like optical recording medium during a recording stand-by time period, which is yielded by a difference between a data rate in inputting information to a disc player 50 and a recording rate in recording information into the optical recording medium. The CAL pattern is reproduced from the optical recording medium, the reproduced pattern is evaluated, and an irradiation intensity of a laser beam is optimized for recording information in the optical recording medium, by a laser-output controller 30. <IMAGE></p> |
