    Abstract: A recording head has a near-field transducer that extends a first distance away from a media-facing surface. Two subwavelength focusing mirrors are at an end of a waveguide proximate the media-facing surface and extend a second distance away from the media-facing surface that is less than the first distance. The subwavelength mirrors are on opposite crosstrack sides of the near-field transducer and separated from each other by a crosstrack gap. The subwavelength focusing mirrors each include a first material at the media-facing surface and a plasmonic material that covers an edge of the subwavelength focusing mirror that faces the near-field transducer. The first material is more mechanically robust than the plasmonic material.

    Abstract: A near-field transducer is situated at or proximate an air bearing surface of the apparatus and configured to facilitate heat-assisted magnetic recording on a medium. The near-field transducer includes an enlarged region comprising plasmonic material and having a first end proximate the air bearing surface. The near-field transducer also includes a disk region adjacent the enlarged region and having a first end proximate the air bearing surface. The disk region comprises plasmonic material. A peg region extends from the first end of the disk region and terminates at or proximate the air bearing surface. The near-field transducer further includes a region recessed with respect to the peg region. The recessed region is located between the peg region and the first end of the enlarged region.

    Abstract: An apparatus (e.g., a heat assisted magnetic recording read/write element) that has an optical component that extends to a location adjacent a media-facing surface of a slider body. The apparatus further includes a planar plasmon antenna that is disposed between the tip portion of the magnetic write pole and the optical component. The planar plasmon antenna can be formed of a plasmonic material operationally capable of a plasmonic excitation in response to an evanescent coupling with an optical mode of the optical component. In some instances, the planar plasmon antenna includes an enlarged region spaced from the optical component and a peg region formed in the enlarged region. The peg region has a thickness in a direction substantially transverse to the optical component that is less than a thickness of a portion of the enlarged region that spaces the peg region from the optical component.
