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 α β γ 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 α β γ 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 α β γ coordinate system being overlappingly set at the position of the point light source.

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： The invention relates to a hologram having authenticating information recorded in such a way that the information is little viewable in an ordinary viewing state and an authenticator can easily check the authenticating information from a color difference, and so having high counterfeit-proofness. In a 3D image-reconstructing hologram 10, a minute object 11 that is authenticating information is located behind a shielding block 12 of visually easy-to-perceive size, so that the authenticating information 11 is hidden by the shielding block 12 in a given viewing direction and so is not exposed to view, but can be viewed from a direction different from the given direction. Further, the authenticating information 11 and the shielding block 12 are recorded in such a way as to be viewable in mutually different colors.

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.
