ABSTRACT:
An apparatus and method for producing a positive crown on a slider air bearing surface. The apparatus includes a reference fixture and a carrier which holds the slider and which is positioned adjacent the reference fixture. An actuator is engageable with the carrier for causing movement of the carrier relative to the reference fixture. By controlling the displacement of the actuator, the carrier can be moved back and forth relative to the reference fixture, thereby producing a positive crown on the air bearing surface of the slider by a lapping element.
