Abstract
Various embodiments relate to an apparatus having an array of sensors sharing a common media-facing surface, each sensor having an active sensing region, magnetic shields flanking the active sensing region, and gaps between the active sensing region and the magnetic shields. At least one of the gaps includes an electrically conductive layer having a refractory material. Other embodiments relate to an apparatus having a sensor with an active sensing region, magnetic shields flanking the active sensing region, and gaps between the active sensing region and the magnetic shields. At least one of the gaps includes an electrically conductive layer having a modified region at a media facing side thereof, the modified region being at least one of nonconductive and mechanically hardened.
