An image recording medium in which a refractive index modulation is recorded in a material in a layer such that, when the hologram recording medium is illuminated from a predetermined angle and a viewpoint is moved horizontally with respect to a normal line, a hologram image having continuous parallax in at least the horizontal direction is reproduced and that, when the viewpoint is moved in a direction with respect to the normal line different from the horizontal direction, another image that is different from and thus is not continuous with the hologram image is reproduced.

A hologram reproduction apparatus and method is disclosed wherein positioning between reproduction reference light and a hologram recording medium can be performed accurately. Reference light is irradiated upon the medium recorded by angle multiple recording, and reproduction light generated from the medium is received by an image pickup apparatus to reproduce data. Thereupon, projection information of light which cannot pass through an iris but is projected on the iris is detected by an optical detector. A position control section detects a positional displacement of the medium based on projection state information on the inner side of a projection region of reproduction light generated from an adjacent recording area to the recording area of a reproduction target from within the detection information and controls a drive mechanism to move the medium so as to eliminate the positional displacement.

A permanent-magnet generator includes a flywheel having a ringlike portion and a bottom portion which closes off one end of the ringlike portion and a plurality of protrusions bulging inward from the bottom portion of the flywheel. An irregular surface portion is formed in each of the protrusions for producing turbulence when the flywheel rotates, the irregular surface portion being irregularly shaped in section along a circumferential direction of the flywheel.

An inline type speckle multiplexed hologram recording apparatus and method is disclosed which can condense signal light and reference light in a sufficiently overlapping relationship with each other on a hologram recording medium without using a lens having a large aperture and a wide angle of view. A signal light region and a reference light region are displayed on a spatial light modulator, and laser light is intensity modulated with recording data displayed in the signal light region to produce signal light while the laser light having passed through the reference light region is used as reference light. The signal light and the reference light are diffused by a diffuser and then condensed in an overlapping relationship with each other on a hologram recording medium by a lens such that interference fringes produced thereby are recorded in the hologram recording medium.

A hologram reconstructing apparatus is disclosed. The apparatus includes: unnecessary light removing means for causing the imaging means to receive necessary light only included in the reconstruction light; driving means for operating the hologram recording medium or a reconstruction light optical system; light detecting means for detecting the state that reconstruction light is projected to the unnecessary light removing means of the light cut by the unnecessary light removing means; and control means for obtaining the displacement of the hologram recording medium based on the information on a specific part of the projection state information detected by the light detecting means and controlling the driving means to cancel the displacement and move the hologram recording medium or the optical system.
