    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： The present invention has an object, in a near-field optical probe having a microscopic aperture to generate and/or scatter a near field, to obtain a near-field optical probe easy to be made in an array which increases the intensity of a near field to be generated and/or scattered and is adapted for use as an optical memory head. This near-field optical probe is arranged with a planar lens having microscopic lens on a flat surface substrate having an inverted conical or pyramidal hole formed therethrough such that its apex is made as the microscopic aperture, wherein a light source is further arranged thereon to introduce light to the planar lens. Because the arrangement is made such that the planar lens has a focal point positioned at the microscopic aperture, the light given by the light source can be efficiently collected to the microscopic aperture. Also, the above structure can be arrayed and mass produced using a silicon process, thus being adapted for use as an optical memory head.

    摘要： In a recording apparatus for reproducing information recorded on a recording medium by utilizing near-field light, the recording apparatus realizes reliable information reproduction with a simple structure. Illumination light 20 is illuminated to the recording medium 10 to create near-field light on a surface of the recording medium 10. The created near-field light is scattered by a microscopic aperture 12 formed in the aperture element 11 so that scattering light (propagation light) thereof is detected to create a reproduced signal. Derived from the created reproduced light a distance control signal representative of a distance between the microscopic aperture 12 and the recording medium 10. Based on the distance control signal, the aperture element 11 is controlled in position. Due to this, the microscopic aperture 12 is brought into proximity to the recording medium 10.

    摘要： A rangefinding/autofocusing apparatus utilizes a joint transform correlator of a Fourier correlation optical system. A pair of imaging lens systems form a pair of object input images. A lens driving mechanism drives the imaging lens systems in a parallel manner. The pair of object input images are recorded for display. A reference input image is displayed concurrently along with the recorded object input images in an offset relation relative to each other. A photodetector disposed on the correlation plane of the Fourier correlation optical system detects correlation peaks corresponding to a correlation coefficient of the pair of displayed object input images to measure an interval between the detected correlation peaks. The photodetector also detects correlation peaks corresponding to a correlation coefficient of the reference input image and the object input images to determine a correlation between the reference image and the object. A calculation unit calculates a distance between the object and the imaging lens systems to determine a just-focused state of the object depending on the measured interval. The lens driving mechanism shifts the imaging lens systems to thereby establish the just-focused state of the object. A target object is recognized depending on the correlation between the reference image and the object after the just-focused state is established.
