Hologram recording method, hologram recording device, hologram playback method, and optical recording medium
A hologram recording method, which records signal light onto an optical recording medium as a hologram, includes: placing a signal light region, which generates signal light, and a reference light region, which generates reference light, symmetrically with respect to an optical axis of coherent light by displaying, on a spatial light modulator which spatially modulates the incident coherent light, a pattern which divides a modulating region into a plurality of regions; generating signal light and reference light by modulating the incident coherent light by the spatial light modulator; simultaneously and coaxially illuminating, onto a reflecting-type optical recording medium, the signal light and the reference light generated from the signal light region and the reference light region disposed symmetrically to one another; and recording the signal light on the optical recording medium as a hologram.
