Abstract: A data writing element may be configured at least with a write pole positioned adjacent a first shield along a first axis and adjacent a second shield along a second axis. The second shield may be separated from the write pole by a first gap distance on an air bearing surface (ABS) and by a second gap distance distal the ABS with the first and second gap distances meeting at a transition surface oriented parallel to the ABS.

Abstract: A recording head includes a layer of plasmonic metal deposited on a surface of the recording head. One or more non-self-supporting layers of crystalline material are attached to the plasmonic metal, the one or more layers of crystalline materials configured to form an active region of a laser. A waveguide is configured to receive plasmons from the laser and direct the plasmons to a recording medium.

Abstract: A mounting surface of a read/write head is prepared to receive an epitaxial layer. The mounting surface is proximate a waveguide of the read/write head, and the waveguide is configured to receive an optical output from the epitaxial layer. The epitaxial layer is transfer printed on to the mounting surface. The mounting surface maintains a vertical alignment between the optical output and the waveguide. The epitaxial layer is processed to form a laser integrated with the read/write head.

Abstract: An apparatus includes an input region having a high-refractive-index material and an input surface configured to receive light emitted from a laser. An output surface of the apparatus is configured to deliver energy to a recording medium. The apparatus includes a plasmonic waveguide having a first elongated portion at an angle to the input surface and configured to receive the light through the input region. In response to receiving the light, surface plasmons are excited and guided to an end of the first elongated portion. The plasmonic waveguide includes a second elongated portion coupled to the end of the first elongated portion and configured to guide the surface plasmons to the output surface.
