The loading device comprises a platform which is movable up and down relative to the turntable, a box with a plurality of disc holders, horizontally slidable into and out of the platform and provided with a hole. The hole in each holder is formed so that the holder can pass the turntable and the light pen unimpededly. The loading device further comprises a transport mechanism engaging the respective holders alongside the platform for moving the respective holders from the box to the platform and a lift mechanism with a lift compartment for the box to move the box to a specific height position. The loading device co-operates with a loading lever with a disc loader for urging a disc on the turntable.
