Abstract: A device including a near field transducer (NFT); a write pole; at least one dielectric material positioned between the NFT and the write pole; and an adhesion layer positioned between the NFT and the at least one dielectric material.

Abstract: A method for providing energy assisted magnetic recording (EAMR) heads using a substrate are described. The substrate has front and back sides and apertures therein. The apertures are through-holes between the front and back sides of the substrate. The method includes providing a transmission medium in the apertures and fabricating EAMR transducers on the front side of the substrate. The EAMR transducers correspond to the apertures and the EAMR heads. The method also includes electrically insulating the back side of the substrate. The back side of the substrate is also prepared for mounting of the lasers. The lasers then are coupled the back side of the substrate. The lasers correspond to the EAMR heads and are configured to provide light through the apertures to the EAMR transducers. The method also includes separating the substrate into the EAMR heads.

Abstract: An apparatus includes a waveguide having a core layer and first and second cladding layers on opposite sides of the core layer, wherein the cladding layers comprise a binary oxide composition. In another example, the cladding layers include a ternary or quaternary combination of oxides and/or oxynitrides. In another example, the cladding layers include a silicon oxynitride.

Abstract: While an emitting position of light from an optical waveguide and a magnetic pole end part are made closer to each other, high-density writing onto a magnetic recording medium is realized. A thermally assisted magnetic head comprises a main magnetic pole layer having a magnetic pole end part exposed at a medium-opposing surface opposing a magnetic disk, and an optical waveguide for deflecting laser light incident thereon into a laminating direction. The main magnetic pole layer is positioned on a side where the light is deflected by the optical waveguide. The magnetic pole end part projects to the side where the light is deflected by the optical waveguide. The optical waveguide projects more than the magnetic pole end part on the medium-opposing surface side.
