Abstract:
A magnetic head according to one embodiment includes a substrate; at least one transducer formed above the substrate, the at least one transducer being selected from a group consisting of a reader and a writer; an overcoat portion formed above the at least one transducer; and a wear resistant portion formed between the overcoat portion and a media-proximal surface of the magnetic head, the wear resistant portion being formed of a material having a greater resistance to media wear than a material from which the overcoat portion is formed.
