ABSTRACT:
A disk cartridge includes a hard jacket having head insert hole. A shutter on the hard jacket is moveable between the open position and the closed position relative to the head insert hole. The front edge of the hard jacket includes a notch defined by at least a bottom wall and a side wall. To make easy the insertion of the disk cartridge into a recording and reproducing apparatus, thereby improving a feeling of operation, the side wall is connected to the front edge by a corner wall whose distance from one side edge of the shutter standing at the open position progressively increases as it approaches the front edge.
