A protective cover (12) for an optical disc readable by a disc reader having a laser. The optical disc (40) has a periphery, a data-read side and a non-data-read side opposite the data-read side. The cover includes a disc of material capable of transmitting light emitted by a laser. The transmitting disc (15) is applicable to the data read side of the optical disc to cover the data-read side. The transmitting disc further comprises a gripper (19) at its periphery for being disposed around the periphery of the optical disc and engaged with the optical disc to hold the transmitting disc generally flat opposite the data-read side of the optical disc without blocking transmission of light emitted by the laser to the data on the optical disc. A method for applying a protective cover to an optical disc. A protective covering apparatus having a protective cover and an alignment device (38) for alignment of the cover on an optical disc.
