Abstract
A method of controlling curvature of a disc head slider having a slider body with a bearing surface, a back surface, which is opposite to the bearing surface, a first axis and a second axis, which is perpendicular to the first axis, is provided. The method includes directing a continuous-wave laser beam toward the back surface to form a laser spot on the back surface. The laser spot is scanned along the back surface in a direction parallel to the first axis or the second axis to form a continuous elongated scan line on the back surface such that the back surface melts and then cools along the scan line to induce anisotropic tensile stress in the back surface, which is oriented predominately parallel to the scan line.
