A protective cover, subject to a removable occupancy by a video disc, is inserted into a video disc player. During the insertion of an occupied cover into the player, an appropriately designed platform leads it to a fully inserted position such that a clamping device built into the player protrudes into the cover. The user then removes the cover allowing the video disc to remain in the player resting on the platform. When the player lid is closed, the platform is lowered to effect a transfer of the video disc resting thereon to the player turntable. Upon playback, the lid is raised to cause the video disc to rise with the platform. An empty cover is then inserted to return the video disc back into the cover. The subsequent withdrawal of the cover removes the enclosed video disc.
