Abstract:
A method of controlling cross and crown curvatures of a bearing surface of a disc head slider, the method comprising:(a) obtaining a measure of the cross and crown curvatures; (b) selectively altering material stresses in a working surface of the slider within an independent cross curvature adjust area based on the measure of the cross curvature; (c) defining the independent cross curvature adjust area such that step (b) induces a change in the cross curvature while inducing substantially no change in the crown curvature; (d) selectively altering the material stresses in the working surface within an independent crown curvature adjust area, which is isolated from the independent cross curvature adjust area, based on the measure of the crown curvature; and (e) defining the independent crown curvature adjust area such that step (d) induces a change in the crown curvature while inducing substantially no change in the cross curvature.
