ABSTRACT:
A magnetic tape head includes a body having a leading edge, a trailing edge and first and second side edges. A raised leading rail, a raised trailing rail and a raised center rail are positioned on the body and extend between the first and second side edges to form a head-to-tape interface. The raised center rail is positioned between the raised leading rail and the raised trailing rail. The raised center rail carries a transducer and has first and second longitudinal slots disposed about the transducer. The first and second slots form relieved surfaces which are recessed from the head-to-tape interface and raised from the body for reducing air bearing surface area around the transducer and causing the transducer to virtually protrude from the head-to-tape interface.
