ABSTRACT:
A flexible cleaning disk for universal application in single sided and double sided flexible disk drives has a jacket, a flexible cleaning medium rotatably positioned within the jacket and a removable protective membrane arranged to normally cover one of the jacket access apertures. The protective membrane is a relatively thin flexible member fabricated from 0.002 inch polyester having a main body portion positioned within the interior of the jacket between the cleaning medium and the access aperture and a tab portion extending laterally from the main body portion and adhered to the outer surface of the jacket adjacent the access aperture. The relatively thin flexible membrane provides a highly efficient transfer medium for the compressive force applied by the pressure pad assembly in a single sided drive and the movable transducer assembly in a double sided drive to the cleaning medium. When used in a double sided drive, the membrane is removed during a second cleaning phase by releasing the tab portion from the jacket surface and withdrawing the main body portion from the access aperture.
