Abstract
In a tray loading type storage medium drive apparatus, a plurality of circular recesses for accommodating a plurality of kinds of circular storage media having different diameters to each other are coaxially formed on a tray. A plurality of movable claw pieces are provided along an outer periphery of an outermost one of the circular recesses. The movable claw pieces are capable of partly protruding over each of the circular recesses.
