Abstract
The invention provides a new method and apparatus for creating smooth and uniform air-bearing surfaces on disk sliders. A lapping fixture includes a compliant pad which allows substantially uniform pressure to be applied between the slider and a lapping surface. Multiple sliders may be lapped simultaneously, with the compliant pad allowing each slider to float substantially independently of the other sliders against the lapping surface. Positioning surfaces are provided on the lapping fixture to position the sliders relative to the lapping surface and to allow a predetermined force to be applied to each slider independent of the force of the lapping fixture against the lapping surface.
