Patent ID: 8291743

Claim:
A method for calibrating an electronic lapping guide (ELG) for least one transducer having an air-bearing surface (ABS) and a magnetic structure, the magnetic structure having a desired thickness, a bevel, and a flare point a distance from the ABS, the method further comprising: providing at least a first ELG, a second ELG, and a third 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; measuring resistances of the first ELG, the second ELG, and the third ELG; and calibrating the at least one of the first ELG, the second ELG, and the third ELG utilizing the offset and the resistances.
