Abstract
An apparatus according to one embodiment includes a magnetic read transducer comprised of a sensing portion and proximate magnetic shields, and a wear-resistant in-situ film on a media-facing side of the read transducer. The in-situ film is comprised of material derived from a flexible medium. The in-situ film is primarily above the read transducer.
