A disk cartridge containing a flexible magnetic recording disk is provided with cover members which are automatically pulled back as the cartridge is inserted into a drive device, thereby providing access to the disk for rotation and transducing. In one embodiment illustrated in Figs. 1-3, the disk cartridge 11 consists of two identical halves 11a, 11b, with a flexible disk 12 in between. The two identical halves of the cartridge have integrally molded latches 13, 14 with circular protrusions 13a, 14a which nest in holes 16 in a cover 21 when in the closed position. On each side of the tray 17 into which the cartridge is inserted are one-revolution wheels 18, 19 with protruding pins 18a, 19a perpendicular to the axis of the wheel.
