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. A method according to one embodiment includes forming a wear-resistant in-situ film on a magnetic read transducer having a sensor with magnetic shields. The in-situ film including material derived from a flexible medium. The material is formed on the transducer by passing the flexible medium over the transducer at an elevated temperature.
