Abstract:
1. A magnetic head comprising: a slider body having a trailing surface meeting an air-bearing surface at a trailing edge; a thin-film transducer disposed on the trailing surface near the trailing edge, the thin-film transducer including a coil embedded between first and second poles, the coil having a first set of turns disposed in a first general plane and a second set of turns disposed in a second general plane; and a resistive heating element, at least a portion of the resistive heating element being disposed between, and electrically insulated from, the first set and second set of turns of the coil, wherein application of power to the resistive heating element causes expansion of at least the first and second poles and wherein the portion is disposed a distance within a range of 20 μm to 60 μm from the air-bearing surface.
