Abstract
An electrical lap guide having a first layer, the first layer including a material having a first resistivity, the first layer having first and second contact regions for electrically connecting the electrical lap guide to electrical leads; a second layer, the second layer including a material having a second resistivity, wherein the electrical lapping guide has a lapping axis and a layered axis, the layered axis being perpendicular to the lapping axis, the electrical lapping guide has an air bearing plane, the air bearing plane being perpendicular to the lapping axis, the second layer is disposed adjacent to a portion of the first layer in the direction of the layered axis, and the first layer extends farther in the lapping axis than does the second layer.
