12 ABSTRACT: The invention relates to a disc player for a rigid information-carrying disc, which player has a disc holder on which the disc rotates during information transfer, the disc holder comprising a turntable and a centring device, which device comprises a plurality of centring elements which are arranged along a circle, which are each resiliently movable in a radial direction in order to keep the disc centred during rotation by means of the centring elements which act on the wall of the centre hole in the disc. A lid which is movable from an open to a closed position in two stages carries a disc loader and is coupled to lifting means. After the disc loader has resiliently urged the disc onto the centring device and the turntable in a first stage, the lifting means lift the lid in a second stage until the disc loader is clear of the disc which is clamped on the centring device. The resilient centring elements firmly retain the disc on the turntable as a result of their radial elastic deflection.
