    Abstract: The disclosed methods enable the production of plasmonic near-field transducers that are useful in heat-assisted magnetic recording. The plasmonic near-field transducers have an enlarged region and a peg region. The peg region includes a peg region in proximity to an air-bearing surface above a recording medium and also includes a flared region between and in contact with the enlarged region and the peg region. The flared region can act as a heat sink and can lower the thermal resistance of the peg portion of the near-field transducer, thus reducing its temperature.
