摘要： A system for providing transducer(s) including a disk structure and having an air-bearing surface (ABS) are described. The disk structure resides a distance from the ABS and has a disk dimension substantially perpendicular to the ABS. Lapping control and disk windage ELGs are provided. The lapping control ELG has first and second edges first and second distances from the ABS. The disk windage ELG has edges different distances from the ABS. A difference between these edges corresponds to the disk dimension. A windage resistance of the disk windage ELG is measured and a disk windage determined. The disk windage corresponds to a difference between designed and actual disk dimensions perpendicular to the ABS. A lapping ELG target resistance is determined based on the disk windage. The transducer is lapped. Lapping is terminated based on a resistance of the lapping control ELG and the lapping ELG target resistance.
