ABSTRACT:
A magnetic disc cartridge is composed of a pair of upper and lower case members superimposed one upon the other so as to form a hard case to accommodate a magnetic disc therein. An aperture for access of a read-write head to the magnetic disc extends in a radial direction, which aperture is selectively covered by a shutter. The case has a groove on the peripheral edge thereof to receive a shutter actuation pin. The groove extends across the adjoining surfaces of the two case members and is formed by a wall member extending integrally from one of the two case members towards the other so as to hide a joining line between the two case members.
