Abstract
A film-based magnetic head cleaning medium in which the head cleaning areas are formed by puncturing the film all the way through with a plurality of sharp prongs to produce an area of projecting puncture edges which are raised from the surface of the film thereby creating roughened areas which scrape accumulated debris from the magnetic head as the film is passed between the magnetic head and facing load pressure pad.
