发明名称 Protective cover for optically read digital disks
摘要 A protective cover for protecting a read side of an optical disk includes 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 disk engaging element. 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 an outer surface of the annular base for receiving and covering the read side of the optical disk.
