In a thermally assisted recording head using a conductive scatterer as an optical near-field transducer, a propagation loss in a waveguide for guiding light to the scatterer is reduced. An optical near-field is generated by using the conductive scatterer having a width that gradually becomes smaller toward a vertex at which the optical near-field is generated. At the same time, a height of the conductive scatterer for generating the optical near-field is made substantially equal to a height of a main pole or longer than the height of the main pole. |
