Summary:An arrangement for centering, aligning and retaining a rigid disc such as a rapidly rotating video disc in an operating position, comprising a centering device mounted on a drive spindle, which device cooperates with a central disc hole in the disc, comprising a disc aligner mounted on the drive spindle for aligning the disc in a plane perpendicular to the axis of rotation of the drive spindle in the operating position of said disc, and comprising a disc loader for loading the disc towards the disc aligner. The disc aligner is rigidly connected to the drive spindle and the centering device comprises a plurality of resilient centering members which cooperate with the wall of the disc hole and which are radially movable between a rest position and an operating position which is situated nearer the axis of rotation of the drive spindle.
