    Abstract: A write head includes a near-field transducer near a media-facing surface of the write head and a waveguide. The waveguide includes a core that overlaps or is co-planer with the near-field transducer at a first region. The core has a second region extending away from the near-field transducer to an energy source. The core has a third region between the first and second regions. The third region has a third crosstrack width that is less than first and second crosstrack widths of the first and second regions

    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.

    Abstract: An apparatus includes a write head comprising a near-field transducer at a media-facing surface of the write head and a waveguide extending along a light-propagation direction. The waveguide is configured to receive light emitted from a light source at a fundamental transverse electric mode. The waveguide is configured to deliver the light to the near-field transducer at a transverse magnetic mode which directs surface plasmons to a recording medium in response thereto. The waveguide comprises a core with first and second tapers separated by a straight portion of constant cross sectional width. The first and second tapers successively decrease a cross-sectional width of the core as it nears the near-field transducer. The waveguide includes an end portion between the second taper and the near field transducer. The end portion comprises a top cladding layer, aside cladding layer, and a bottom cladding layer on the side cladding layer.
