Abstract:
A method for providing a desired curvature in air bearing surfaces of each of a plurality of sliders, comprising:a) performing the following steps in at least two installments:i) measuring a curvature of the air-bearing surface of each slider in a row of sliders of the plurality;ii) determining a curvature difference between the curvature measured in step (i) and a final target curvature for each slider in the plurality;iii) while the sliders are still in the row, scribing a pattern on a back surface of each slider in the plurality at each installment to correct for a portion of the curvature difference, wherein the pattern for each slider in the row has different scribe lines; andiv) while the sliders are still in the row, scribing a partial length scribe line on the back surface of each slider in the plurality in a final installment to achieve the final target curvature, wherein the partial length scribe line does not extend entirely across the back surface.
