20140254336 | NEAR-FIELD TRANSDUCER WITH FLARE PEG - Disclosed are plasmonic near-field transducers that are useful in heat-assisted magnetic recording. The disclosed plasmonic near-field transducers have an enlarged region and a flared region. In some embodiments the disclosed plasmonic near-field transducer can also include a peg region. The flared region can act as a heat sink and can lower the thermal resistance of the peg region of the near-field transducer, thus reducing its temperature. Also disclosed are methods that include delivering light to a magnetic transducer region via a waveguide, receiving the light at a plasmonic near-field transducer having an output end and disposed in proximity to the magnetic transducer region, and delivering a surface plasmon-enhanced near-field radiation pattern proximate the output end of the plasmonic transducer in response to receiving the light, | 09-11-2014 |
20140307534 | APPARATUSES AND METHODS FOR CONTROLLING NEAR-FIELD TRANSDUCER TO WRITE POLE SPACING - 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. | 10-16-2014 |
20150016774 | METHOD FOR REGULATING PATTERNED PLASMONIC UNDERLAYER - The embodiments disclose a stack feature of a stack configured to confine optical fields within and to a patterned plasmonic underlayer in the stack configured to guide light from a light source to regulate optical coupling. | 01-15-2015 |
20150017482 | METHOD FOR FABRICATING PLASMONIC CLADDING - The embodiments disclose a plasmonic cladding structure including at least one conformal plasmonic cladding structure wrapped around plural stack features of a recording device, wherein the conformal plasmonic cladding structure is configured to create a near-field transducer in close proximity to a recording head of the recording device, at least one conformal plasmonic cladding structure with substantially removed top surfaces of the stack features with exposed magnetic layer materials and a thermally insulating filler configured to be located between the stack features. | 01-15-2015 |
20150043315 | NEAR-FIELD TRANSDUCER WITH ENLARGED REGION, PEG REGION, AND HEAT SINK REGION - A near-field transducer includes an enlarged region having a top side adjacent to a magnetic pole, a base side opposite the top side, and a circumference that extends from proximal to a media-facing surface to distal to a media-facing surface. The near-field transducer includes a peg region in contact with a region of the bas side of the enlarged region, the peg region extending from the enlarged region towards the media-facing surface. The near-field transducer also includes a heat sink region having a contact side, a base side, and a circumference that extends from proximal to the media-facing surface to distal from the media-facing surface. The contact side of the heat sink region is in thermal contact with both the peg region and at least a region of the base side of the enlarged region. | 02-12-2015 |
