摘要:
An optical disk apparatus according to the present invention is an optical disk apparatus for performing at least one of: recording data to a plurality of types of optical disks including a recordable optical disk and a read-only optical disk which are produced according to the BD specifications; and reproducing data from the optical disks. This apparatus includes: a means (506, 507) for irradiating a management area 502 of an optical disk 501 with a light beam while not performing tracking control, and generating a track position signal (push-pull TE or phase difference TE) from light which is reflected by the management area 502; and a disk determination means for determining, based on the track position signal obtained from the management area 502, whether the optical disk 501 mounted in the optical disk apparatus is a recordable optical disk or a read-only optical disk.
