ABSTRACT:
A method of manufacturing a transducing sub-assembly for a magnetic head assembly comprising the steps of affixing a transducer onto a substrate wherein the transducing element is located on one side thereof and leads extending from the transducing element are located on a different side thereof and wherein the substrate is formed of a material which is highly resistant to being abraded by a recording medium being transported thereacross and wherein the transducer is affixed to the support surface with the transducing element located adjacent the medium contacting surface and with the leads extending along the supporting surface away from the medium contacting surface; bonding a spacer to the substrate and transducer wherein the substrate and spacer are formed of a material which is highly resistant to being abraded by a recording medium and has a medium contacting surface of a preselected width and spaced sidewalls extending substantially perpendicular therefrom a distance equal to the length of the transducing element; bonding an electrical circuit means to the substrate and transducer wherein the electrical circuit means terminates in an edge having a width which does not exceed the preselected width and wherein the exposed conductors are positioned in electrical contact with the leads of the transducer and in opposed, spaced alignment from the spacer and applying a clamping force to the transducing subassembly during the bonding steps is shown. A product formed by using the process is also shown.
