Abstract
A disk holding device for a disk having a center hole is provided. A disk holding mechanism is movable between a holding position and a release position, for engagement with an edge of the center hole when in the holding position, and for coming away from the edge when in the release position. A solenoid as actuator shifts the disk holding mechanism, to hold the disk by setting the disk holding mechanism in the holding position, and to release the disk by setting the disk holding mechanism in the release position. A regulating portion contacts a peripheral portion of an upper surface of the disk, to keep the disk retained on the disk holding mechanism by preventing skew relative to the disk holding mechanism. Preferably, the disk holding mechanism enters the center hole downwards and holds the disk on a lower side.
