An apparatus and method for controlling twist curvature of a disc head slider is provided, where 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 obtains a measure of the twist curvature of the bearing surface and selectively alters material stresses in a working surface of the slider. The material stresses are altered asymmetrically with respect to the longitudinal axis and the transverse axis based on the measure of the twist curvature to induce a change in the twist curvature.
