Abstract:
1. A method for providing at least one transducer including a disk structure and having an air-bearing surface (ABS), the disk structure residing a distance from the ABS and having a disk dimension substantially perpendicular to the ABS, the method comprising: providing a lapping control ELG and a disk windage ELG for each of the at least one transducer, the lapping control ELG having a first edge a first distance from the ABS and a second edge a second distance from the ABS, the disk windage ELG having a third edge a third distance from the ABS and a fourth edge a fourth distance from the ABS, a difference between the third edge and the fourth edge corresponding to the disk dimension; measuring a windage resistance of the disk windage ELG; determining a disk windage based on the windage resistance, the disk windage corresponding to a difference between a designed disk dimension perpendicular to the ABS and the disk dimension; determining a lapping ELG target resistance based on the disk windage; lapping the transducer; and terminating the lapping based on a resistance of the lapping control ELG and the lapping ELG target resistance.
