ABSTRACT:
To provide an excellent optical information recording method, optical information recording medium and optical information recording apparatus both of which use the method. The method generates no excessively-exposed region, can sufficiently fix recorded information, and never reduce the sensitivity of non-recorded regions. This is achieved because the method applies a fixing beam onto at least a portion of an exposed region of a recording layer of the optical information recording medium, the recording layer recording information by holography, at an exposure level T (mJ/cm2) that satisfies the condition H<(S+T)<2H (where S is an integrated exposure level (mJ/cm2), which is the total of the exposure level in each predetermined region that constitutes the exposed region where an interference image has been recorded by irradiating the recording layer with an information beam and a reference beam, and H is a minimum fixing exposure level (mJ/cm2) required to fix the interference image).
