摘要： The object of the present invention is to provide an information recording/reproduction device for implementing high-density information recording and reading using mutual interaction of a recording medium with near field light, and particularly to a near field optical head with a high optical efficiency and a manufacturing method thereof. This is achieved by enabling an energy propagation mechanism via a plasmon by forming a layer dispersed with metal particulate at a microscopic opening generating near field light, and therefore increase optical efficiency.

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.

摘要翻译：在用于通过利用近场光再现记录在记录介质上的信息的记录装置中，记录装置以简单的结构实现可靠的信息再现。照明光20被照射到记录介质10上以在记录介质10的表面上产生近场光。所产生的近场光被形成在孔径元件11中的微小孔12散射，使得散射光（传播光）被检测以产生再现信号。从创建的再现光中衍生出表示微小孔12和记录介质10之间的距离的距离控制信号。基于距离控制信号，孔径元件11被控制在适当位置。由此，使微细孔12靠近记录介质10。

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： An apparatus for producing optical aperture is disclosed. A pressing body has a plane covering a tip and at least a part of stoppers. An opaque film formed on the tip. The pressing body is displaced toward the tip for forming an aperture on a point of the tip. According to the apparatus, the amount of displacement of the plate can be controlled excellently by the stopper and can be made very small. Thus, the aperture having a uniform and small size can be produced on the point of the tip easily.
