description A slider includes a reader element, a bottom shield located adjacent to the reader element, a top shield located adjacent to the reader element, a heater, a substrate located below the reader element, the top shield, the bottom shield and the heater, and a cap substantially surrounding the reader element, the top shield, the bottom shield and the heater. The cap includes a base coat layer comprising a first electrically insulative cap material adjoining the substrate, and an overcoat layer comprising a second electrically insulative cap material adjoining the base coat layer opposite the substrate. The base coat layer and the overcoat layer meet at an interface located at or below the top shield. The first and second electrically insulative cap materials are different.
