摘要： When recording on a holographic recording medium by using a recording beam, the time required for an asking servo control to recover is reduced to increase the data transfer rate. In the holographic recording apparatus 10, a laser beam from a laser light source 16 is formed into a collimated beam having an expanded beam diameter and then is divided into an object beam and a reference beam. The divided object beam is modulated according to information to be recorded, and these object and reference beams are made incident on the reflective surface of a rotating polygon mirror 18, while maintaining collimated beam shapes and being adjacent to each other, through a condenser lens 24 having a focal point behind the reflective surface of the polygon mirror 18. The object and reference beams are made incident on the holographic recording medium 12 moving in the same direction as their scanning direction with angles different from each other so as to interfere with each other within the holographic recording medium 12.

摘要： An optical recording medium has a plurality of information layers which are placed between a substrate and an optically transparent cover layer with optically transparent spacer layers interposed between the information layers. From among the plurality of information layers, the information layer excluding the information layer arranged closest to the substrate and the information layer adjacent to the information layer closest to the substrate has asymmetrical reflection characteristics in which reflectance on the substrate side when light incident from the substrate side is reflected on the information layer toward the substrate side is lower than the reflectance on the cover layer side when light incident from the cover layer side is reflected on the information layer toward the cover layer side.

摘要： An optical system includes a negative refraction lens and a compensating element. The negative refraction lens is a flat plate formed by a material exhibiting negative refraction, and a surface on which light is incident and a surface from which the light is emerged are formed to be flat and parallel. The compensating element is an optical element which makes light incident at a predetermined angle, emerge at another predetermined angle. A light ray is emitted from an object point on an object plane, and reaches an image point on an image plane after being refracted twice by a negative refraction lens. The light ray is reflected by the compensating element, then refracted at an emergence-side pupil, and reaches the image point upon being reflected once again by the compensating element.
