摘要： In an information recording apparatus for recording information onto a recording medium by utilizing a technology in a near-field microscope, the information recording apparatus carries out recording with reliability and density. An optical probe (1) or micro-cantilever (12) utilized in a near-field microscope is used as a recording probe (26). The recording probe (26) at its tip is heated by laser light (28) illumination or heating by an electric heating element to radiate microscopic-region thermal energy through the tip to a recording medium (3). This makes it possible to record microscopically information onto the recording medium (3) that varies in physical properties due to heating. Furthermore, thermal energy is provided to a recording position through an auxiliary heat radiating means thereby enabling recording more positively.

摘要： A near-field optical head has a slider having a minute aperture for emitting near-field light. The minute aperture has a diameter equal to or less than a wavelength of visible light. The slider is supported by a suspension arm for exerting a load, receiving a floating force due to relative movement with a recording medium, and forming a gap between the slider and the recording medium through a balance between the load and the floating force. A light propagating medium has an output end for emitting light. An optical path length shortening structure shortens an optical path length between the output end of the light propagating medium and the minute aperture of the slider. A mirror is disposed over the slider for guiding light emitted from the light propagating medium to the minute aperture of the slider.

摘要： A near-field optical probe has a hole penetrating through a substrate and defining a microscopic aperture at an apex thereof for generating or scattering near field light. The probe is simple and inexpensive to produce and may be manufactured in an array form by forming plural holes in the substrate so that it may be used in an optical memory device. A lens is disposed above the microscopic aperture for focusing incident light and a light source is arranged thereover to introduce light to the lens. A focal point of the lens is positioned at the microscopic aperture, so that the light emitted by the light source can be efficiently collected at the microscopic aperture. The structure can be mass produced using known silicon processing techniques, thus being adapted for use as an optical memory head.

摘要： A near-field optical probe with a resolving power exceeding a diffraction limit of light is provided utilizing near-near-field light. A near-field optical probe is formed by a core and a shading film. The core has a tip surface spotted with inwardly depressed points with respect to the surface. This provides within the tip surface a light intensity distribution in a distributed form instead of a conventional rectangle function. Its Fourier expansion is increased in short-wavelength lattice constant component. Utilizing this component, a near-field optical probe is realized having a resolving power exceeding a diffraction limit of light.
