摘要:
An optical information recording apparatus includes a first optical system that radiates an information beam that carries information onto a recording medium; a second optical system that radiates reference beams onto the recording medium; a radiation position specifying unit that specifies a plurality of recording spots positioned within a radiation range of the reference beams; and an incident angle obtaining unit that specifies an incident angle of the reference beams that is used for recording an i'th interference fringe into a second recording spot adjacent to a first recording spot, as a value obtained by adding a product of 1/(1+m) and an absolute value of a difference between an incident angle of a first reference beam used for recording an i'th interference fringe into the first recording spot and an incident angle of a second reference beam used for recording an (i+1)'th interference fringe into the first recording spot.

An optical recording medium includes a first substrate having a groove on the side of an outer peripheral portion thereof; a second substrate in contact with the first substrate in the outer peripheral portion; and a recording layer being disposed in a gap between the first substrate and the second substrate and forming a void in cooperation with the first substrate at the portion of the groove.
摘要:
The present invention relates to a powdery photosensitive material comprising evenly dispersed components and free from a variation in quality, and an optical recording medium produced from the photosensitive material. The photosensitive material is produced by a process including freezing a solution of components that constitutes the photosensitive material dissolved in a first solvent and then drying the resultant solid under reduced-pressure.

According to one embodiment, an image display apparatus includes a light source, a modulation unit, a first array and a second array. The modulation unit modulates intensity and a color of the light to generate beams corresponding to each of modulated pixels included in a modulated pixel group. The first array is formed by juxtaposing a plurality of first deflection elements each having a generating line parallel to a vertical direction of the modulated pixels. The second array is formed by juxtaposing a plurality of second deflection elements each having a generating line tilted by an angle represented by tan−1(α×m/n) with respect to a generating line of the first deflection element.
