摘要： A recording head comprises a write pole extending to an air-bearing surface. A near-field transducer is positioned proximate a first side of the write pole in a down-track direction. A heatsink structure is proximate the near-field transducer and positioned between the near-field transducer and the write pole. The heatsink structure extends beyond the near-field transducer in a cross-track direction and extends in a direction normal to the air-bearing surface.

摘要： A recording head includes a waveguide core layer that delivers light from a light source to a region proximate a magnetic write pole. A near-field transducer that is formed of a thin metal film is deposited over the waveguide core layer. The near-field transducer includes an enlarged part with two straight edges facing a media-facing surface and at obtuse angles relative to the media-facing surface. A peg extends from the enlarged part towards the media-facing surface. The near-field transducer includes a metal aperture plate at the media-facing surface. The metal aperture plate surrounds at least three sides of the end of the peg.

摘要： An apparatus includes a detector, a light source configured to emit light, a plurality of disks, and a focusing apparatus. Each disk includes a set of prisms, and each disk is independently rotatable, arranged to receive the emitted light directly or indirectly from the light source, and arranged to receive backscattered light from an object. The focusing apparatus is arranged to focus the backscattered light from the plurality of disks towards the detector.

摘要： A near-field transducer includes an enlarged portion formed of a soft plasmonic metal. A diffusion barrier is formed on one side of the enlarged portion, the diffusion barrier made of a harder material than the soft plasmonic metal. A heat sink is formed on the diffusion barrier, the heat sink made of the soft plasmonic metal. A peg is embedded in the diffusion layer so that the peg is isolated from the enlarged portion and the heat sink. The peg made of the soft plasmonic material and extends out from the diffusion layer towards a recording medium.
