摘要： Provided is a thermal-assisted-magnetic-recording head capable of directing, to a magnetic recording medium, light in which the spot size is reduced to submicron order with high total optical propagation efficiency. A light coupling unit that guides light emitted from the light source into a magnetic head and a high-refractive-index core that couples with the light guided by the light coupling unit to lead the light to an air bearing surface are arranged in the magnetic head. The light coupling unit includes a plurality of thin-film-like cores that are separated from each other by a clad material. An upper part of the high-refractive-index core is placed between two thin-film-like cores.

摘要： A thermally assisted recording magnetic head is provided in which a magnetic recording medium can be irradiated with light having a spot size reduced in the submicron order with high total optical propagation efficiency. In a magnetic head, a spot size converter that propagates the light from an optical source in the magnetic head is provided adjacent to a main pole. The spot size converter includes a cover layer having a refractive index lower than that of a clad material and formed in contact with the optical waveguide core, and is formed in a shape composed of a substantially rectangular shape in a light traveling direction and a tapered shape where the width is increased toward the bottom surface of the magnetic head. The optical waveguide core having the cover layer formed is vertically interposed between multi-mode-thin-film-like cores that can excite a first or higher-order optical waveguide mode.
