Abstract
A method for laser edge treating (LET) a slider and a slider with laser edge treatment, wherein the laser treatment is used to modify the curvature along the air-bearing surface, including altering a slider edge ridge that forms at the edges of the air bearing surface due to compressive stresses induced in the air bearing surface by a prior lapping step. The laser makes positive and negative adjustments to crown, cross curve, and twist as measured on the air bearing surface by selectively altering the treatment pattern or the treatment location on the slider's side edges.
