Abstract
A disk device for playing back information recorded on an optical disk, includes a device body; a disk tray, moving in the device body between a charging position, into which the optical disk is charged, and a discharging position from which the optical disk is discharged; a chassis, provided in the device body; a turntable, moving between an ascending position and a descending position when the chassis is displaced, and the turntable on which the optical disk is set; and a disk clamper, pivotally arranged on an upper plate of the device body, and clamping the optical disk against the turntable when the turntable is moved to the ascending position. The disk clamper is arranged on the upper plate with a clearance therebetween so that the disk clamper is moved in all radial directions, and an amount of the clearance in a first direction, in which the disk tray moves from the discharging position to the charging position, is smaller than amounts of the clearance in the other directions.
