ABSTRACT:
A magnetic head and a method of producing a magnetic head for use with magnetic contact recording media which passes over the magnetic head in contact therewith, thus, exerting a pressure on the magnetic head. The magnetic head includes a transducer support having a side with two generally coplanar raised elongated facing surfaces which have a space between them and are generally aligned along a longitudinal axis which is transverse to the direction in which the media travels across the magnetic head. The magnetic head further includes a core located in the space between the two facing surfaces. The core has an elongated surface which extends in the direction in which the media travels to a greater extent than at least a portion of the facing surfaces. The core also has a transducer element embedded within it. The combination of the facing surfaces, the elongated surface of the core and the transducer element form a generally coplanar wear surface. The dimensions of the wear surface which extend in the media travel direction are selected to effect a predetermined wear of the wear surface as the media advances across the wear surface.
