ABSTRACT:
The apparatus for lapping a magnetic head slider includes a lapping plate to which a bar of the magnetic head slider makes a contact by a predetermined lapping pressure, a primary oscillating mechanism that makes a primary oscillating of the bar in a radial direction of the lapping plate, and a secondary oscillating mechanism that makes a secondary oscillating of the bar in a direction perpendicular to a direction of the primary oscillating. A coarse lapping of the bar is performed by a combined oscillating of the primary oscillating and the secondary oscillating, and upon completion of the coarse lapping, the apparatus switches to the primary oscillating to finish lapping of the bar.
