  • Publication number: 20150071045
    Abstract: An apparatus includes a waveguide and a near-field transducer adjacent the waveguide. The near-field transducer includes an enlarged region and a peg region extending from the enlarged region towards an air bearing surface. A write pole is adjacent the near-field transducer and include a first portion having an edge extending towards the air bearing surface at a non-orthogonal angle with respect to the air bearing surface. A second portion of the write pole extends orthogonally to the air bearing surface and is in contact with the first portion. The apparatus includes an insulator-filled gap at the air bearing surface between the second portion of the write pole and the peg region of the near-field transducer. The gap is bounded away from the air bearing surface by the enlarged region of the near-field transducer.

  • Publication number: 20150043316
    Abstract: An apparatus comprises a write transducer comprising a write pole having a tip portion proximate a media-facing surface and a return pole spaced apart from the write pole in a downtrack direction. The apparatus further includes first and second heat sink portions. The first heat sink portion surrounds a first side of the tip portion that faces the return pole and extends outwards from the tip portion in a cross-track direction. The second heat sink portion comprises a first surface proximate the first heat sink portion and a second surface proximate the return pole and extends outwards in the cross-track direction further than the first heat sink portion.

  • Patent number: 8891205
    Abstract: An apparatus is provided that includes a waveguide adjacent an air bearing surface, a near-field transducer comprising a peg having a side orthogonal to the air bearing surface and a write pole adjacent to the waveguide. The write pole includes a first portion extending towards the air bearing surface at a non-orthogonal angle with respect to the air bearing surface, and a second portion in contact with the first portion comprising a side that extends towards and orthogonally contacts the air bearing surface. The second portion or the write pole defines a gap between the side of the peg orthogonal to the air bearing surface and the side of the second portion of the write pole that extends towards and orthogonally contacts the air bearing surface. A method of making a magnetic recording head that includes the provided apparatus is also disclosed.

  • Patent number: 8873352
    Abstract: An apparatus has a near-field transducer located proximate a media-facing surface of a slider magnetic recording heat. A waveguide is configured to couple light to the near-field transducer and includes a top cladding layer facing the near-field transducer, a bottom cladding layer, and a core layer between the top and bottom cladding layers. The apparatus includes a write pole with a flat portion substantially parallel to the core layer and a sloped portion extending from the flat portion of the write pole towards the media-facing surface at an angle to the core layer and to the media-facing surface. A light mitigation layer is located between the top cladding layer and the write pole.

  • Patent number: 8804283
    Abstract: A write pole can have a magnetically conductive pole tip has at least one corner. The at least one corner may be chamfered to limit magnetic saturation of the conductive pole tip. The conductive pole tip can have one or more beveled surface that has a chamfered corner which extends a predetermined distance along an edge of the write pole.

  • Publication number: 20140207250
    Abstract: A process of forming a tissue scaffold is described, the process comprising electrospinning polymer fibers from a spinneret onto a tissue scaffold template. In embodiments, the fibers are plasma-treated between the spinneret and the template. The scaffold may be constructed of alternating layers of aligned and randomly oriented fibers. The scaffold may be heat treated to control the mechanical properties of the scaffold, such as density, pore size and pore interconnectivity.
