ABSTRACT:
A magnetic head includes a slider having an air bearing surface (ABS) and a trailing surface, with a transducer fabricated on the trailing surface. The transducer includes an adjunct pole disposed in a first general plane, the adjunct pole having a front edge that is recessed from the ABS and a rear edge. A main pole of the transducer is formed adjacent the adjunct pole, the main pole having a write tip that extends approximately to the ABS. A write coil having a first layer of turns is disposed in a second general plane below the adjunct pole. The magnetic head further includes a heating element, a portion of the heating element being disposed in the first general plane behind the rear edge of the adjunct pole.
