    Abstract: A plasmonic transducer includes at least two metal elements with a gap therebetween. The metal elements are placed along a plasmon-enhanced, near-field radiation delivery axis. Cross sections of the metal elements in a plane normal to the delivery axis vary in shape along the delivery axis. The metal elements have a reduced cross section portion at a media-facing surface oriented normal to the delivery axis. A dielectric material surrounds the reduced cross section portion of the plasmonic transducer at the media-facing surface, and reduces deformation of the metal elements proximate the media-facing surface at elevated temperatures.

    Abstract: A magnetic recording head consists of a write pole and a near field transducer close to the write pole that focuses light energy to a focal point. A near field transducer is positioned to receive light energy from a waveguide. The near field transducer comprises an energy-receiving end and an energy-radiating end. The energy-receiving end is located near the focal point of the waveguide and the energy-radiating end is shaped such that it is narrower closer to the write pole and wider farther from the write pole.
