Abstract
A protective cover for protecting a read side of an optical disk, including a circumferential frame for receiving and engaging the optical disk and a shield. The frame includes a continuous end wall, an annular base extending radially inwardly from a lower edge of the end wall and a plurality of spaced apart tabs extending radially inwardly from an upper edge of the end wall for engaging an upper surface of an optical disk. The shield is transparent and has an inner edge defining a central opening, an outer edge and a generally planar annular surface extending between the outer edge and the inner edge. The shield is carried by the annular base for receiving and covering the read side of the optical disk.
