摘要： A near field light generating element has a polyhedron core and a clad covering the core so as to contact side surfaces of the core. The polyhedron core has a reflection surface that reflects a luminous flux in a direction different from a direction of introduction of the luminous flux via one end side of the near field light generating element. A luminous flux condensing unit condenses the luminous flux reflected by the reflection surface and propagates the condensed luminous flux to the another end side. A near field light generation unit generates near field light from the propagated condensed luminous flux and emits the near field light to the exterior of the near field light generating element via the another end side. The near field light generation unit has an end surface that is exposed to the exterior on the another end side and has at least one side surface that is shielded by a light-shielding film.

摘要： A near-field optical head has a slider with first and second inclined surfaces that confront a magnetic recording medium during recording and reproduction of information. A recording element is formed on one of the first and second inclined surfaces and includes main and auxiliary magnetic poles stacked together with an insulation film interposed therebetween. An optical flux introducing device introduces an optical flux toward the first and second inclined surfaces of the slider, the optical flux having an optical axis inclined relative to the first and second inclined surfaces. A metal film is formed on the other of the first and second inclined surfaces of the slider for propagating the introduced optical flux along an interface between the first and second inclined surfaces to generate near-field light that is irradiated on the surface of the magnetic recording medium to effect recording and reproduction of information.

摘要： This invention provides a method of, and an apparatus for, producing a near field optical head that can control a height of an optical aperture or a protuberance and an air bearing surface. A substrate and a protuberance formed on the substrate are covered with a shielding film. The shielding film is covered with an parent film for air bearing having a thickness greater than the sum of a height of the protuberance and a thickness of the shielding film. When the parent film for air bearing is etched, the shielding film covering the protuberance is exposed. Etching is stopped as soon as exposure of the shielding film is detected. Since detection of the exposure of the shielding film can be made electrically, for example, a height difference between the aperture and the surface of the air bearing can be controlled highly precisely.
