ABSTRACT:
In order to enable recording and reproduction from optical disks with defect management formatted with different group configurations without changing the firmware of the conventional apparatus and to allow the size of the spare area to be specified at initialization, the position information indicating the position of the defect management area is recorded in the control data area provided in the read-only area of the optical disk, and the information indicating the first address or size of the spare area is included in the defect management area.
