Abstract
An optical information recording apparatus and method thereof for recording information in a holographic medium. The apparatus includes a laser source which generates a reference beam and a signal beam to record the information in the holographic medium, a sensor which detects a vibrational amplitude over a time period applied to the optical information processing apparatus for recording the information, an operational circuit which calculates from the vibrational amplitude at least one statistical measure of the vibrational amplitude; and a processor programmed to control a recording mode such that the processor evaluates the calculated statistical measure to determine continuation of a recording operation to the holographic medium.
