Abstract
A cleaning device for cleaning contact-type information transducing heads is disclosed. The device has a substrate covered in part by a cleaning material and partly by a recording surface. A program is stored on the recording surface for directing the transducing head toward cleaning material for each cleaning operation. An embodiment is disclosed in which memory locations on the recording surface count the number of cleaning program executions, indicate specifically available cleaning areas and indicate when the cleaning device has been completely used.
