Abstract
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.
Claims20
A method, comprising,
- 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,
- wherein the material is formed on the transducer by passing the flexible medium over the transducer at an elevated temperature above normal reading temperature.
A method, comprising,
- determining resistances of read transducers;
- comparing the determined resistances to previously-stored resistance values;
- and
- in response to determining that the measured resistances have significantly changed from the previously-stored resistance values, causing the read transducers to be heated to above a normal operation temperature, and causing a flexible medium to run over the read transducers for forming an in-situ film on the read transducers.
