ABSTRACT:
A multiple channel magnetic tape head assembly defines a plurality of spaced-apart transducer elements along an integral bar of ferromagnetic material. Each element, formed by grinding operations performed upon the integral bar, has a magnetic gap and flux circuit which is isolated from cross-talking with the other elements. Each element is precisely located by the integral bar, portions of which remain after grinding. The head assembly provides an aligned longitudinal tape wear region and may further provide widened transverse wear regions adjacent to each of the transducer elements. A fabrication method for forming a multiple channel magnetic tape head assembly is also described.
