ABSTRACT:
A hologram recording method is disclosed in which: signal light includes a plurality of arranged reversal regions in which lightness and darkness of plural pixels of a light and dark image is reversed for an intensity distribution of the light and dark image; the signal light is Fourier-transformed; the Fourier-transformed signal light and reference light are illuminated onto an optical recording medium; and the signal light is recorded as a hologram. Also is disclosed an apparatus capable of implementing the hologram recording method, and an optical recording medium usable with the method.
