摘要： Two original images to be recorded are prepared as data (S10). A plurality of unit regions, each having an adequate area to record interference fringes of visible light, are defined and positioned on a hologram recording surface (S20). A gradation pattern, with which appearance probabilities of two record attributes gradually change in space, is overlapped onto the recording surface, and to each unit region, one of either record attributes is assigned according to the appearance probabilities of the respective record attributes at each individual position (S30). In each unit region, to which the first record attribute is assigned, the first original image is recorded as an interference fringe pattern, a diffraction grating pattern, or a scattering structure pattern, and in each unit region, to which the second record attribute is assigned, the second original image is recorded as an interference fringe pattern, a diffraction grating pattern, or a scattering structure pattern (S40), and a record pattern is formed on a physical medium (S50).

摘要： Arrangements are made to enable different original images to be reproduced upon observation from different positions and yet enable reproduced images of high resolution to be obtained. In a case of recording two original images, each of the two original images Ia and Ib is defined as a set of point light sources in an XYZ global coordinate system, and two propagation spaces Sa and Sb, each enabling propagation of light emitted from an origin Q of an αβγ local coordinate system, are defined. A predetermined recording plane and a reference light are set in the XYZ coordinate system, and an interference fringe pattern, which is formed on the recording plane by object light components from the point light sources constituting the respective original images and the reference light, is determined by computation. In this process, the computation is performed upon deeming that a light from a point light source belonging to the original image Ia spreads only within the propagation space Sa, with the origin Q of the αβγ coordinate system being overlappingly set at the position of the point light source, and that a light from a point light source belonging to the original image Ib spreads only within the propagation space Sb, with the origin Q of the αβγ coordinate system being overlappingly set at the position of the point light source.

摘要： Embodiments of the invention prevent a spindle motor from stopping rotation while data on a magnetic disk is being erased by using a permanent magnet. In one embodiment, data in the whole area of the magnetic disk is erased as a consequence of the magnetic disk rotating in the magnetic field of the permanent magnet located so as to face a part of the magnetic disk. A back yoke is located so as to face a base. The back yoke gives a magnetic force to the spindle motor in the opposite direction of the magnetic force of the erasing permanent magnet so that the fluid dynamic bearing spindle motor can retain the rotation as required without stopping rotation.

摘要： An original image (10), a recording surface (20), and a reference light (R) are defined and a large number of calculation points (Q(x, y)) are defined at a predetermined pitch on the recording surface (20). For each of the calculation points, intensity of interference wave, formed by an object light (O1 to ON) generated from the respective parts (P1 to PN) of the original image (10) and a reference light (R), is calculated. A binary pattern defined by dividing a unit area into a first area having a pixel value “white” and a second area having a pixel value “black” is defined in a plurality of ways by changing the occupancy ratio (0 to 100%) of the first area. A binary pattern having the occupancy ratio corresponding to the interference wave intensity calculated, is assigned to the position of the respective calculation points (Q) on the recording surface (20) so as to form a binary image and create a computer hologram medium having convex and concave portions. By setting the vertical and horizontal pitched of the calculation points (Q) to 400 nm or below, it is possible to reduce the unnecessary noise component generated during observation and obtain a clear reproduction area.

摘要： A complex amplitude type spatial optical modulation element, with which the amount of generation of 0th-order diffraction light is low, is provided. An optical element is arranged by aligning a plurality of three-dimensional cells C1(x, y) two-dimensionally on an XY plane. Each individual cell is made of a light transmitting material and has a specific amplitude and a specific phase defined therein. On the upper surface of each individual cell, a first region, in which a groove G(x, y) is formed, and a second region, positioned at both sides of the first region, are formed, and light blocking layers F1 and F2 are formed on upper surfaces of the second region. The first region, which is a bottom surface of groove G(x, y) is set to an area (G1×G3) that is in accordance with the specific amplitude defined in the corresponding cell, and the depth (G2) of groove G(x, y) is set to a value that is in accordance with the specific phase defined in the corresponding cell. Incident light from the upper surface of a cell is modulated by the specific amplitude and the specific phase in being transmitted to the lower side of the cell. The unnecessary noise light is cut by light blocking layers F1 and F2.
