  • Patent number: 9576595
    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.

  • Patent number: 9099130
    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.

  • Patent number: 8649125
    Abstract: The application discloses pole tip shield assemblies for a magnetic write element. The shield assemblies disclosed include side shields to limit adjacent track interference. The side shields are truncated or notched at a midpoint to form an expanded non-magnetic gap along a trailing portion of the pole tip to enhance write field and/or field gradient. The expanded non-magnetic gap region is larger than the non-magnetic gap region along a leading portion of the pole tip.

  • Publication number: 20110243176
    Abstract: A method of producing a slider wafer populated with electromagnetic components optically aligned with photonic elements for HAMR applications. Laser chips are transferred from a laser substrate wafer to the slider wafer by a massively parallel printing transfer process. After wafer bonding the laser chips to the slider wafer, the shape and optical alignment of the photonic elements are precisely aligned en masse by lithographic processing.
