ABSTRACT:
A method and apparatus for lapping the air bearing surfaces of hard disk head sliders including the steps of installing a lapping plate charged with lapping abrasive onto a lapping contour plate, applying a negative pressure to a cavity of the lapping contour plate communicating with the charged lapping plate to deform the lapping plate into conformance with a contour of the lapping contour plate, applying a lapping force to a slider in contact with the lapping plate, and moving the slider relative to the lapping plate to form an air bearing contour following the contour of the lapping contour plate.
