摘要:
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
