摘要 <p>A protective cover (10) for protecting a read side of an optical disk (40), including a circumferential frame (14) for receiving and engaging the optical disk (40) and a shield (12). The frame (14) includes a continuous end wall (24), an annular base (20) extending radially inwardly from a lower edge (28) of the end wall (24) and a plurality of spaced apart tabs (26) extending radially inwardly from an upper edge (28) of the end wall (24) for engaging an upper surface (45) of an optical disk (40). The shield (12) is transparent and has an inner edge (17) defining a central opening (18), an outer edge (16) and a generally planar annular surface extending between the outer edge (16) and the inner edge (17). The shield (12) is carried by the annular base (20) for receiving and covering the read side (46) of the optical disk (40).</p>
