Abstract
A disk cartridge comprises a case with an upper and a lower shell halves united together to accommodate a disk of 3.5 inches therein, a guide portion, a shutter, and a slider slid in the guide portion of the case for supporting the shutter. The shutter is moved by a drive pin to open and close a head and spindle holes. The slider enables the shutter to move smoothly along the guide portion and prevents the shutter from being disconnected from the guide portion when the case is dropped.
