An apparatus for adjusting curvature of a disc head slider having a bearing surface is provided. The apparatus includes a light source and an apparatus for controlling the light source. The light source is adapted to produce a light beam capable of altering material stresses in a working surface of the slider. The apparatus for controlling the light source is adapted for obtaining a measure of first and second curvature characteristics of the bearing surface and for scanning the light beam across the working surface in a pattern to alter the material stresses in the working surface such that the first and second curvature characteristics move to within predetermined specifications. The pattern is based on the measures of the first and second curvature characteristics and estimates of responses in the first and second curvature characteristics to the pattern.
