Abstract
An electrical lapping guide has a body with a thickness along a wafer axis, the body comprising a layer of conductive material having a resistivity. The conductive material layer comprises a first contact region and a second contact region, the first and second contact regions configured to electrically connect the electrical lapping guide to electrical leads. A lapping edge comprises an air-bearing plane axis perpendicular to a lapping axis, and a back edge opposite the lapping edge, the back edge comprising a plurality of notches.
