ABSTRACT:
An optical disk drive that can automatically adjust an erase power to an appropriate level to keep the error rate low and not to shorten the life of an erasable optical disk. The optical disk drive obtains a reference erasing modulation factor using a test area of the erasable optical disk when the disk is set. While overwriting data in the erasable optical disk, the optical disk drive obtains an erasing modulation factor based on the read signal detected in an erased region from time to time to adjust the erase power so that the erase power continually adjusted to the appropriate level.
