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 electrically conductive ceramic layer of the spacer has a different composition than the electrically conductive ceramic layer of the second spacer.
