A hologram recording method includes eliminating a DC component from a Fourier transformation image of a signal light for expressing binary digital data as a brightness image, and irradiating an optical recording medium simultaneously with the signal light from which the DC component has been eliminated and a reference light to record an image edge portion of the signal light onto the optical recording medium as a hologram.
