Abstract
A disk player for setting an initial position of an optical pickup based on disk recognition places the optical pickup in the closest position to an initial position of the loaded disk, to swiftly recognize a type of the disk and quickly reproduce information recorded on the disk. The initial optical pickup is moved to any position between the TOC area of a mini-disk and that of a compact disk. In this state, a system controller judges whether the loaded disk is a mini-disk or a compact disk based on the signal read from the disk via the optical pickup. If the signal read from the disk is a stored signal, the system microcomputer judges that the loaded disk is a mini-disk and moves the optical pickup to a start position of the TOC area in the mini-disk. On the other hand, if the signal read from the disk is not a stored signal, the system microcomputer judges that the loaded disk is a compact disk and moves the optical pickup to a start position of the TOC area in the compact disk.
