Abstract
In an optical disc apparatus, a loading operation and an unloading operation are performed a plurality of times while changing the movement speed of a tray. A movement speed of the tray at which a shock that is produced during a movement of the tray is smaller than an upper limit, and a time period required for the loading operation and the unloading operation is shortest is determined as the movement speed of the tray in the loading operation and the unloading operation. An optical disc placed on the tray can be prevented from being damaged by a shock produced during a movement of the tray, and the time period required for the loading operation and the unloading operation can be prevented from being prolonged.
