Abstract
An apparatus, according to one embodiment, includes a sensor having an active region, a magnetic shield adjacent the active region, a spacer between the active region and the magnetic shield, a second magnetic shield on an opposite side of the active region as the magnetic shield, and a second spacer between the active region and the second magnetic shield. Both spacers include an electrically conductive ceramic layer. The sensor is an electronic lapping guide.
