Abstract: A magnetic head assembly having a transverse guiding surface which is highly resistant to being abraded by a recording medium for reading and recording magnetically recorded information on the recording medium including a transducer having a transducing element on one end thereof and conductive leads extending from a different end thereof, a substrate formed of a mixture of Aluminum Oxide and Titanium Carbide ("Al.sub.2 O.sub.3 --TiC") having a medium contacting surface and a supporting surface extending substantially perpendicular therefrom wherein the substrate has the transducer rigidly affixed to the substrate supporting surface with the transducing element positioned adjacent the substrate contacting surface, a spacer formed of Al.sub.2 O.sub.

Abstract: A thin film magnetic head having a substrate, a magnetic head and a superstrate formed of materials which are highly resistive to being abraded by a magnetic media being moved thereacross is shown. The magnetic head includes a bottom pole piece having a front gap section and a rearwardly extending portion positioned at predetermined locations on the substrate. The bottom pole piece forms a bottom support for a coil having a plurality of coil windings. An insulating structure having a thin gap defining section and a thick coil windings enclosing portion is located on the bottom pole piece such that the thin gap defining portion establishes the thickness of a magnetic transducing gap and the thick coil windings enclosing portion encloses and surrounds that portion of the coil windings supported by the bottom pole piece.

Abstract: A thin film magnetic head having a substrate, magnetic head components and a superstrate formed of materials which are highly resistive to being abraded by a magnetic media being moved thereacross is shown. The magnetic head includes a magnetic bottom pole piece having a front gap section and a rearward extending portion. A lateral wall layer formed of a magnetic material and of predetermined thickness, has a forward wall section and a rearward wall section which define a coil windings receiving trench adjacent the front gap section of the bottom pole piece layer. The bottom pole piece forms a bottom enclosure for the coil windings receiving trench. A coil having coil windings is formed on the bottom pole piece and the coil windings thickness is less than the thickness of the lateral wall layer.
