ABSTRACT:
A method of operating a transducer includes heating a write element by passing a preheat electrical current through a conductive coil of the write element in a manner which produces a substantially zero magnetic flux. The method also includes writing data to a media after heating the write element by passing a write electrical current through the conductive coil in a manner in which produces a net magnetic flux.
