Abstract
A storage disk drive mechanism is disclosed for rotatably driving a storage disk comprising a flexible circular information recording medium attached to a hub member. The hub member is of the type having an enlarged central positioning aperture and a radially spaced drive aperture. The drive mechanism comprises a rotatable clutch plate having an axial positioning pin for receiving the positioning aperture of the hub member when a disk assembly containing the storage disk is mounted thereon. The clutch plate further has a spring member mounted thereon having a smooth uninterrupted laterally extending beveled claw extending into the driving aperture. Upon rotation of the clutch plate, the claw drivingly engages a driven surface defined by the driving aperture for centering, retaining and driving the storage disk.
