PURPOSE: A tape head having reduced pole-tip recession is described that a wear is reduced by reducing the pole tip recession. CONSTITUTION: In the tape head (30), a recessed substrate (37) and a closure (32) of the tape head are separated by a plurality of layers, which include, for example, a bottom layer (35), a recessed bottom pole (86), a write gap (88), a shared pole (84), a read gap (60), a top pole (82) and a top layer (48). 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.
