Abstract
A method and apparatus for providing a signal for driving a heating element in a TAR or HAMR enabled disk storage system that includes an optical transducer (or near-field optical source) for further focusing the beamspot of a laser onto a magnetic media, thereby heating the media. The storage system includes a temperature sensor proximate to the near-field transducer which provides a feedback loop to the laser driver to adjust the power of the laser.
