Abstract
A tray loading apparatus includes a tray, a motor, a drive circuit. The tray is movable between a load position and an unload position. The motor is constructed and arranged for bringing the tray to move from the unload position to the load position. The drive circuit is used for apply a loading voltage to the motor and the loading voltage includes at least one gradually increasing stage. A tray unloading apparatus and an optical disc drive are also provided.
