Abstract:
1. A wafer comprising: at least one transducer having an air-bearing surface (ABS) and including at least one magnetic structure having a bevel and a flare point a first distance from the ABS, the at least one magnetic structure being characterized by a desired thickness; at least one electronic lapping guide (ELG) including a first ELG, a second ELG, and a third ELG of the at least one ELG, the first ELG having a first edge a first distance from the ABS and a second edge a second distance from the ABS, at least one of the first distance and the second distance corresponding to an intersection between the bevel and the desired thickness, the second ELG having a third edge a third distance from the ABS and a fourth edge the second distance from the ABS, at least one of the third distance and the second distance corresponding to the intersection between the bevel and the desired thickness, the third ELG having a fifth edge a fourth distance from the ABS and a sixth edge the second distance from the ABS, the first distance, the third distance, and the fourth distance corresponding to a stripe height and an offset, at least one of the fourth distance and the second distance corresponding to the intersection between the bevel and the desired thickness.
