Abstract

A disc cartridge includes a cartridge main body (4) which accommodates an optical recording medium (5), such as an optical disc or a magneto-optical disc, and which includes an aperture (8) to expose the optical recording medium (5) at least partially to outside, a shutter (12) to open or close the aperture (8), a shutter resetting spring to bias the shutter towards a side closing the aperture and a shutter locking member (24) to maintain the shutter (12) at a position closing the aperture (8). A shutter opening/closing member introducing groove (16) having its open end on a side (9) of the cartridge main body normal to the shutter sliding direction, is formed along the front side (11) of the cartridge main body (4) parallel to the shutter sliding direction and has the free end of the shutter locking member (24) exposed partially to the groove (16) to enable the disc cartridge to be loaded to a cartridge loading section of recording/reproducing apparatus with the shutter sliding direction as the introducing or loading direction.
