Abstract
A magnetic write head includes a magnetic yoke having a first pole and a second pole. The first pole and the second pole each terminate at an air bearing surface. The first pole is magnetically coupled to the second pole in a backgap region. The magnetic write head further includes a electrically conductive write coil magnetically coupled to the magnetic yoke. The magnetic write head further includes a resistive heater coil having a first coil turn and a second coil turn. The heater coil is electrically isolated from the write coil. At least a portion of the first coil turn is between the first pole and the second pole and between the air bearing surface and the backgap region. At least a portion of the second coil turn is between the first pole and the second pole and between the air bearing surface and the backgap region. The portion of the first coil turn overlaps the portion of the second coil turn.
