Apparatus for recording optical information
摘要:
Optical information is stored in an optical information recording medium having an information recording layer utilizing holography with an optical information recording apparatus which includes security features. An input device is used to input individual information which is unique to an individual. An information light carries information to be recorded on the optical information recording medium. A phase modulation pattern is generated based on the individual information. A recording reference light is generated including a phase modulator for spatially modulating a phase of the reference light, for generating reference light for recording having a phase spatially modulated based on the phase modulation pattern information. A recording optical system illuminates the information recording layer on the same side with both the information light and the reference light.
