<p>In order to easily identify the correct direction of insertion into a recorder/player and assure a large width of an access opening through which the optical head approaches an optical disc, a disc cartridge includes an access opening (21) formed in a cartridge body (6) and through which a part of the recording area of an optical disc (5), extending between lead-in and lead-out areas, is exposed outside for data read and write, a pair of shutter members (25,26) are provided movably towards and away from each other to open and close the access opening (21), and a shutter open/close mechanism (27) includes a pair of guide recesses (36a,36b) formed in a main side of the cartridge body (6) obliquely in relation to the width of the cartridge body (6) to support the pair of shutter members (25,26), respectively, to be movable. <IMAGE></p> |
