Abstract

A disk apparatus includes a disk guide member, a disk transfer mechanism, a disk rotating section, a disk clamp mechanism, and a control section. The guide member has a pair of detectors arranged in the disk transfer direction with a predetermined distance therebetween so as to be brought into a detection state by a peripheral edge of a disk when the disk reaches such a position as to be clamped by the disk rotating section. The control section operates the disk clamp mechanism so that the disk rotating section is urged toward the disk when one of the detectors is brought into a detection state during the transfer of the disk, determines that a clamping operation of the disk is completed when both of the detectors are in a detection state and the detection state continues for a predetermined time, and then stops the disk transfer mechanism.
