ABSTRACT:
Embodiments of the present invention allow control over the element height of read and write heads without damage to a lapping surface table when an air-bearing surface is lapped with a row bar or magnetic head slider tilted. According to one embodiment, the air-bearing surface is lapped with the row bar tilted in the longitudinal direction of a slider to compensate element height-wise positional deviations of the read head and the write head. The lapping is performed while changing an inclination angle stepwise and swinging the row bar in the longitudinal direction of the slider centering around an inclination angle at each step. Thus, the element heights of the magnetic pole piece and the read element can be controlled without damage to a lapping surface table.
