Optical information recording method, optical information recording apparatus, and optical information recording/reproducing apparatus

摘要

[OBJECT] An object is to provide an optical information recording method for recording information accurately on an information recording layer of a recording medium by utilizing interference between information light which carries information by spatial modulation and recording-specific reference light and an optical information recording/reproducing apparatus. [MEANS TO SOLVE] Information light 1 which carries information by spatial modulation and recording-specific reference light 2 are interfered with each other in an information recording layer 4 of a recording medium, and diffusion of the recording-specific reference light 2 is controlled so as not to cause interference between each recording-specific reference light 2 in the information recording layer 4 when information is recorded through the interference pattern.
