Thermally assisted recording head and thermally assisted recording device

摘要

The thermally assisted recording head using a scattering material having conductivity as a near field light generating element, to reduce the propagation loss in the waveguide for guiding light in the scatterer. At the same time generating a near-field light using a scatterer conductive width becomes gradually smaller toward the apex of the near-field light is generated, the height of the scattering material having conductivity for generating near-field light and to be substantially equal to the height of the main pole for generating a magnetic field, and, or to be greater than the height of the main pole.
