    • A magnetic head includes a slider body having a trailing surface meeting an air-bearing surface at a trailing edge and a thin-film transducer that includes a magnetic reproducing element with a magnetoresistive (MR) element disposed near the trailing edge within a gap material bounded by upper and lower shield layers. The thin-film transducer also includes a lower pole layer of a magnetic recording element disposed in a first general plane. The magnetic recording element further includes a coil having first and second turn layers disposed in second and third general planes, respectively. The magnetic head also includes resistive heating element with at least a portion of the heating element being disposed in a fourth general plane beneath both the lower pole layer and the coil but above the upper shield layer. Current flow through the heating element causes expansion of the magnetic reproducing and recording elements at the ABS.
