A disc cartridge capable of holding a disc in a casing in a state of floating in a space in the casting to keep it in noncontact with the casing when the disc cartridge is not used. The disc cartridge includes an actuator arranged in a casing receiving a disc therein to releasable lock a shutter for a window and a disc receiver arranged in the casing and operatively connected to the actuator to selectively receive therein a part of a peripheral portion of the disc. The actuator is arranged to be slidable in a longitudinal direction of the disc cartridge to cause the disc receiver to be approachably moved with respect to the disc, so that the disc receiver may be engaged with the disc to rearwardly force the disc while keeping the disc in noncontact with the casing when the shutter is actuated to close the window and disengaged from the disc when the shutter is actuated to open the window.
