Abstract:
A method for providing at least one transducer including magnetic structure and having an air-bearing surface (ABS) are described. The method includes providing a lapping electronic lapping guide (lapping ELG) and a targeting ELG. The lapping ELG and targeting ELG each are coplanar with the desired thickness of the magnetic structure and have a back edge at the distance from the ABS such that the ELG back edges are substantially aligned with the flare point. The targeting ELG has a front edge at a front edge distance from the ABS corresponding to an intersection of the bevel and the desired thickness. The method further includes lapping the transducer and terminating the lapping based on a first resistance of the lapping ELG and a second resistance of the targeting ELG.
