Abstract
An apparatus for adjusting twist curvature of a slider is provided, wherein the slider has a bearing surface, a back surface, which is opposite to the bearing surface, a longitudinal axis and a transverse axis. The apparatus includes a light source adapted to produce a light beam capable of altering material stresses in a working surface of the slider. The apparatus further includes an apparatus for obtaining a measure of the twist curvature of the bearing surface and for scanning the light beam across the working surface in a pattern selected to alter material stresses in the working surface asymmetrically with respect to the longitudinal axis and the transverse axis based on the measure of the twist curvature so as to induce a change in the twist curvature.
