Thermally-assisted magnetic recording head having heat radiation layer and interposed layer
A thermally assisted magnetic head includes a main magnetic pole layer, a near-field light generating layer having a generating end part generating near-field light arranged within a medium-opposing surface, and an optical waveguide guiding light to the near-field light generating layer. The near-field light generating layer has a near-field light generating part in a triangle shape with the generating end part being one vertex, and is formed in a triangle pole shape. The optical waveguide is formed to be opposed to a ridge part of the near-field light generating layer via an interposed layer. The main magnetic pole layer is formed to be opposed to the generating end part via the interposed layer. The thermally assisted magnetic head further includes a heat radiating layer in contact with an opposite side of the near-field light generating layer from the optical waveguide.
