Abstract
An apparatus includes a waveguide that has a core between the first and second cladding layers. A near-field transducer in the first cladding layer is configured to receive the energy from the waveguide and deliver the energy to a recording medium. A reflector in the second cladding layer is configured to reduce reflection of the energy from the recording medium back to an energy source.
