摘要
The present invention provides a tape head with reduced pole-tip recession. A recessed substrate and a closure of the tape head are separated by a plurality of layers, which include, for example, a bottom layer, a recessed bottom pole, a gap layer, a top pole and a top layer. The recessed bottom pole is positioned in the recess of the substrate. By utilizing the recessed substrate and the recessed bottom pole, the thickness of the overcoat layer is reduced, thereby reducing the distance between the substrate and the closure at an air-bearing surface of the recording head. With the present invention, wear is reduced, thereby reducing pole tip recession.
