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 light source and a waveguide are mounted on a recording head slider. Light rays are emitted from the light source into the waveguide. The waveguide may include two core layers for light ray transmission. The first core layer enhances light coupling efficiency from the light source to the second core layer. The second core layer transforms a profile of the light. The waveguide may include a tapered portion with a narrow opening near the light source and a wider opening near the tapered portion exit. The light rays passing through the waveguide may be directed toward a collimating mirror. The collimating mirror makes the light rays parallel or nearly parallel and re-directs the light rays to a focusing mirror. The focusing mirror focuses the collimated light rays to a spot on a magnetic media disc.
