Abstract
A disk apparatus includes a chassis and a tray supported on the chassis, the tray being provided to be movable between a disk-change position and a disk-loaded position. A disk holder holds a disk on the tray at a given position. A movable base supports a turntable thereon, the turntable being provided to support and rotate the disk on the turntable, the movable base being provided to be vertically rotatable between a lowered position and a lifted position. A clamper clamps the disk between the turntable and the clamper. A movable base drive unit actuates the movable base to the lifted position by a driving force of a motor when the tray is moved to the disk-loaded position, such that the disk is clamped between the clamper and the turntable. The movable base drive unit includes a slider which actuates the movable base to the lifted position and presses the disk holder in a radial direction of the disk to separate the disk holder from the disk at the same time as the actuation of the movable base.
