Embodiments in accordance with 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, when a row bar is tilted in the longitudinal direction of a slider to lap its air-bearing surface according to the positional deviations of a read element and a main magnetic pole piece, an inclination angle thetac is changed stepwise in order of thetac, thetax and thetat, with respect to a target inclination angle thetat and the row bar is lapped while being swung by alpha in the longitudinal direction of the slider around an inclination angle at each step. A swing width a is controlled to gradually attenuate. Thus, the element heights of the magnetic pole piece and the read element can be controlled without damage to a lapping surface table.
