Method of controlling a rotational rate of an optical disc and optical disc recording device using the same |
摘要 |
An optical disc recording device controls a rotational rate of an optical disc and an optical disc recording device recording using a constant angular velocity method, thereby efficiently using the performance of the optical disc. A CPU reads management information (a maximum address value) for a farthest recording region, which is located at a circumference farthest from a center of the optical disc. A distance from the center of the optical disc to the farthest circumference of the recording region is calculated based on the read maximum address value. The rotational rate is calculated based on the calculated distance so that the recorded data rate of the farthest recording region is a maximum recorded data rate for the optical disc, and therefore is set to be used by a servo controller.
