Abstract
A cartridge having a case which accommodates a disc, the case having a receiving opening and a longitudinal opening extending from the receiving opening through which an information reproducing apparatus chucks and accesses the disc, a shutter movably mounted on the case, the shutter opening/closing the longitudinal opening and a part of the receiving opening, and a covering part moved by the movement of the shutter so as to completely close the open part of the receiving opening which is not closed by the shutter. When the cartridge is not in use, the receiving opening and the longitudinal opening are not exposed, while the same are open when the cartridge is in use so that the information is recorded/reproduced on/from the disc accommodated therein. In addition, the cartridge can be compact-sized.
