Abstract
A device is provided for gripping a disk-like recording medium on a turntable. The recording medium is provided with a core, the core being formed with a central aperture and a positioning aperture. The central aperture has a pair of adjacent edges that are substantially perpendicular to each other, and the position aperture has a peripheral-side edge and a forward-side edge. The disk gripping device is characterized in that a contact point of a fulcrum hole of a swingable member with a fulcrum pin is held at a substantially predetermined edge position of the fulcrum hole which is nearest to a drive pin, both before and after the recording medium is gripped on the turntable.
