ABSTRACT:
A device for cleaning the magnetic heads in flexible disk equipment or the like. The device includes a cleaning disk made of an absorbant and porous fibrous material having an area saturatable with a liquid cleaning solution. The cleaning disk is rotatably supported within an essentially flat shell made of plastic or other material, the shell being similar to the plastic shells often used to contain flexible magnetic disks used in such equipment. The shell includes on one side an opening enabling the cleaning disk to come into contact with a magnetic head. Opposite the opening on the other side of the cleaning disk is disposed a removable member. In one embodiment, this member is a spring biased to press the cleaning disk against the magnetic head, while in another embodiment a flexible spring is pressed by a pressure pad of the flexible disk equipment against the cleaning disk so that the cleaning disk is pressed against the magnetic head, the flexible spring protecting the pressure pad from the cleaning disk and cleaning solution used. In each embodiment, the spring is removable to expose an opening in the second side of the plastic shell opposite the first opening so that the magnetic heads in flexible disk equipment using oppositely disposed magnetic heads may be simultaneously cleaned. The shell is also provided with one or more other openings which expose the cleaning disk to facilitate saturation of a portion of the cleaning disk with a liquid cleaning solution while leaving a portion of the cleaning disk dry. When the device is placed within a flexible disk system which rotates the saturated disk, the magnetic head or heads are cleaned in a nonabrasive fashion with an alternating wet-dry action.
