ABSTRACT:
A device for centering a disc to be read or recorded while rotating includes a turntable and a plurality of centering parts resiliently connected thereto and extending above the supporting surface thereof concentrically about the axis of rotation. Each centering part has a pair of connection strips connected thereto remote from its free end and extending toward the axis of rotation, each connection strip also extending toward and being connected to an adjacent connecting strip extending from another connecting part. Deflecting a free end of any centering part toward the axis of rotation causes other such parts to be likewise deflected, thereby assuring concentricity of the disc with the axis.
