Abstract
A cleaning system for flexible disk equipment or the like. The system includes a cleaning disk made of an absorbent and porous fibrous material which has an area substantially saturated with a liquid cleaning solution. The cleaning disk is rotatably supported within a flat jacket. The jacket includes opposed openings on either side so as to expose a portion of the cleaning disk to enable the disk to come into contact with a magnetic head or heads. At least one of the openings is enlarged to expose a relatively large portion of the surface of the cleaning disk, so as to facilitate complete saturation of an area of the cleaning disk with a liquid cleaning solution while leaving a portion of the cleaning disk dry. The jacket containing the disk is placed within a flexible disk system which rotates the saturated disk, thus causing the magnetic head(s) to be cleaned in a non-abrasive fashion with a wet, dry, wet action. An improved jacket for use with a thickened cleaning disk is also disclosed.
