Summary: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.
