    摘要： According to one embodiment, an apparatus includes a near field transducer comprising a conductive metal film having a main body and a ridge extending from the main body and an optical waveguide for illumination of the near field transducer, a light guiding core layer of the optical waveguide being spaced from the near field transducer by less than about 100 nanometers and greater than 0 nanometers. In another embodiment, a method includes forming a near field transducer structure and removing a portion of the near field transducer structure. The method also includes forming a cladding layer adjacent a remaining portion of the near field transducer structure, wherein a portion of the cladding layer extends along the remaining portion of the near field transducer structure and forming a core layer above the cladding layer. Other apparatuses and methods are also included in the invention.

    摘要： A write head structure for use with thermally assisted recording is disclosed. Improved heat sinking is provided for removing thermal energy created by a ridge aperture near field light transducer. Metal films conduct heat away from the region near the ridge aperture to the high pressure air film at the ABS between the head and media. This heat is further dissipated by the media. The metal films have varying thickness to improve lateral conductivity and may be composed of Au combined with a harder metal such as Ru to improve wear characteristics at the ABS.
