Abstract
A magnetic tape head including a transducer disposed between a substrate, a recession between the transducer and the substrate, where the recession is formed at least by wear from a magnetic tape. The magnetic tape head also includes a heater disposed in the transducer. The heater thermally expands the transducer at a particular location such that the recession is reduced at the particular location.
