摘要： A thermally assisted write head having a plasmonic heating device. The plasmonic heating device has a plasmonic antenna located at an air bearing surface of the thermally assisted write head. The plasmonic antenna is constructed of an alloy that is sufficiently hard to withstand the processes such as ion milling and chemical mechanical polishing used to construct the plasmonic antenna. The plasmonic antenna is preferably constructed of AuX, where X is Cu, Ni, Ta, Ti, Zr or Pt having a concentration less than 5 atomic percent.

摘要： A thermally assisted magnetic write head having a near-field transducer, a magnetic lip and a diffusion barrier layer between the near-field transducer and the magnetic lip. The near-field transducer includes a transparent aperture constructed of a material such as SiO2 and an opaque metallic antenna constructed of a metal such as Au formed at a first edge of the aperture. A magnetic lip, connected with the write pole is formed near a second edge of the aperture with a diffusion barrier layer being disposed between the magnetic lip and the aperture. The diffusion barrier layer prevents migration of atomic between the aperture and the magnetic lip, thereby ensuring robust performance at localized high temperatures generated by the near-field transducer.

摘要： An apparatus for cooling a nanowire in a wire assisted magnetic recording head using a radiator in close proximity to a shield of the write pole. The radiator may further contain current restraints (e.g., slits, cuts, or resistive materials) that maximize current density in the nanowire at a location that corresponds to the current restraints. These current restraints may be further arranged to align with a write pole such that the current is forced to flow primarily through the nanowire when the nanowire is closest to the write pole. The nanowire may then be used either as main or auxiliary writing element for recording signals to a high coercivity media. Moreover, the nanowire and radiator may be combined into a single nanofoil which has a least two portions that perform a similar function as both the nanowire and radiator.
