Summary:PROBLEM TO BE SOLVED: To provide a hologram recording method onto a hologram recording carrier which can be miniaturized. SOLUTION: The hologram recording method includes processes of spatially modulating a coherent reference light beam according to recording information to generate a signal light beam; irradiating a recording medium with the signal light beam in such a manner that the beam passes to an incident light processing region from the recording medium; and forming a region of a diffraction grating by a light interference pattern in an area where the zero order light of the signal light beam and the diffracted light in the recording medium interfere. The side opposite to the incident side of the signal light beam of the recording medium is provided with an incident light processing region where the plane of polarization of the zeroth order light of the signal light beam made incident through the recording medium and the plane of polarization of the diffracted light are varied from each other.
