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.3 --TiC having a medium contacting surface which is rigidly affixed in an opposed, spaced relationship to the substrate supporting surface with the transducer located therebetween forming a transducing assembly having the transducing element positioned between the substrate medium contacting surface and the spacer medium contacting surface to define a transverse guiding surface adapted to be contacted by a recording medium traversing along a path which is substantially parallel to and in contact with the transverse guiding surface, and a flexible electrical circuit electrically connected to the conductive leads of the transducer for conducting electrical signals representative of the magnetically recorded information on the recording medium is shown.
