Abstract: A recording head includes a near-field transducer proximate a media-facing surface of the recording head and a waveguide that overlaps and delivers light to the near-field transducer. The recording head includes subwavelength-sized focusing mirror comprising first and second reflectors disposed on cross track sides of the near-field transducer. Each of the first and second reflectors is spaced apart from the media-facing surface by a distance, D, measured along an axis normal to the media-facing surface.

Abstract: 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.

Abstract: A near-field transducer includes an enlarged portion and a peg protruding from a first edge. The enlarged portion has a second edge facing away from the first edge. The near-field transducer includes a heat sink disposed on the enlarged portion and with an outline shape that matches that of the enlarged portion. The heat sink is disposed at a first separation distance from the first edge of the enlarged portion and a second, greater, separation distance from the second edge of the enlarged portion. The first separation distance is greater than the second separation distance.

Abstract: A data writer can have at least a write pole separated from first and second side shields by a continuous dielectric gap layer. Each side shield may have first and second shield sub-layers configured with different magnetic moments that increase relative to the sub-layer's distance from the write pole. The side shields may wrap around a leading tip of the write pole to form a box shield.

Abstract: A write head having reduced dimensions. In one implementation, the write head has a main pole having a leading side and a trailing side, a leading yoke on the leading side of the main pole, and a coil wrapped around the main pole and the leading yoke. The coil on the leading side and the leading yoke having a distance of no greater than 300 nm therebetween, and the coil on the trailing side and the main pole having a distance of no greater than 350 nm therebetween. In an alternate implementation, the write head has a trailing yoke, with the coil on the trailing side and the trailing yoke having a distance of no greater than 350 nm therebetween.
