In the present invention, an order on which servo-control manner is sequentially applied is determined in advance based on various depth to respective recording layers of a CD, a DVD, and a high-density DVD, and when a disk is placed a servo-control manner is sequentially selected in the determined order. Therefore, a collusion between a disk and an optical pickup can be prevented for any type of disk.
