ABSTRACT:
A multi-track longitudinal magnetic tape head capable of writing data to high-coercivity magnetic tapes is disclosed. The multi-track, longitudinal magnetic tape head according to the present invention comprises a plurality of write elements and read elements. The write elements comprise a write pole separated from a substrate by a write gap. The write poles each comprise a block of magnetic material, having a planar gap surface and a convex top surface. A high B.sub.s composition is deposited on an etched portion of the magnetic material of each write pole at the gap surface. As a result, the gap surface comprises high B.sub.s composition extending from the top convex surface to a point part way down the gap surface. A method for manufacturing this multi-track longitudinal tape head is also disclosed.
