ABSTRACT:
A disk cartridge comprises a cartridge case including an upper case, a lower case and a head insertion aperture at a predetermined position, a pair of cleaning sheets respectively secured to inner surfaces of the upper and lower cases, a disk disposed rotatably between the cleaning sheets, and a resilient member disposed between at least one of the cases and associated cleaning sheet, the resilient member being adapted to press a part of the cleaning sheet against a disk surface, wherein the resilient member is disposed in the vicinity of the head insertion aperture and upstream of the head inserting port in the rotational direction of the disk, thereby enhancing the effect of cleaning of the disk surfaces to be read/written by the magnetic head.
