Abstract:
A disk device is capable of quickly identifying an inserted optical disk. A reading portion obtains disk surface information from an optical disk that is passing, and stores the obtained disk surface information in a storing portion provided in a disk playing device. An identifying portion decides whether or not the disk playing device is able to play the optical disk, based on the surface information.
