  • Patent number: 9899041
    Abstract: A write pole of a data writer may have at least one rotational milling operation conducted on a write pole blank followed by first and second static milling operations executed at different first and second angles with respect to an air bearing surface. The combination of rotational and static milling operations can form a write pole with body and tip regions defined by a continuous pole sidewall extending perpendicularly from the air bearing surface up to a body taper portion angled at approximately 14.5° with respect to the air bearing surface.

  • 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.
