Abstract

A cleaning tape for an apparatus of the type which includes a magnetic head and a drive mechanism for the head includes a cleaning member adapted to be moved past the magnetic head during a cleaning operation. The cleaning tape defines an array of raised surfaces, at least some of which are separated by smooth, low friction surfaces interposed therebetween. The raised surfaces and low friction surfaces are arranged such that both the raised surfaces and the low friction surfaces alternately come into contact with the magnetic head during a cleaning operation. The raised surfaces are effective to clean the magnetic head, and the low friction surfaces are effective to reduce friction between the cleaning member and the magnetic head to protect the drive mechanism against excessive frictional loading. A press forming method is disclosed for fabricating the cleaning tape.
