DISK DEVICE

摘要

The present invention aims at providing a disk device capable of identifying quickly an inserted optical disk. A reading portion 105 obtains disk surface information from an optical disk 101 that is passing, and stores the obtained disk surface information in a storing portion 106 provided in a disk playing device 100. An identifying portion 107 decides whether or not the disk playing device 100 is able to play the optical disk 101, based on the surface information.
