摘要： A U-shaped groove and a V-shaped groove are formed onto a cladding disposed on a substrate, a core and a metal structure are formed inside the grooves, respectively, and then the substrate surface is planarized. Further, after a cladding is formed again, the substrate is cut and the cut surface is polished such that the metal structure inside the V-shaped groove has a predetermined thickness, thereby forming a scattering body.

摘要： A magnetic recording medium in which information can be recorded using a heat-assisted magnetic recording method comprises a recording layer formed on a substrate. The recording layer has a plurality of magnetic recording bit regions and a plurality of high thermal conductors each extending inside a corresponding one of the bit regions. The high thermal conductors have a thermal conductivity higher than that of the recording layer and assist in dissipating heat energy imparted to the bit regions during the recording of information.

摘要： A near-field light generating element has a core that propagates light flux from a light incident side to a light emission side while focusing the propagating light flux. A near-field light generating portion in the form of a metal film generates near-field light from the light flux. The core includes a first core, and a second core covering a side surface of the first core, and the core is formed in a polygonal shape when viewed from a Z direction. The metal film is placed on a side surface in the core, and is formed so that a width of an interface between the metal film and the core is narrower than a width of the side surface of the core.
