Abstract
Recording heads for a data storage system include a first side having at least a portion of a metal component. A carbon overcoat is on the first side and covers the at least a portion of a metal component. A corrosion inhibitor is incorporated in the carbon overcoat. The corrosion inhibitor is illustratively located between the carbon overcoat and the at least a portion of a metal component, on top of the carbon overcoat, or within the carbon overcoat. In an embodiment, the carbon overcoat includes diamond-like carbon.
