Title:
RECORDING MEDIUM AND HOLOGRAPHIC PROCESS FOR FORMATION OF THE SAME
Document Type and Number:
Japanese Patent JP3696458
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain an improved recording medium in which a hologram shows desirable properties by including a fixing step to subject the recording medium to fixing after irradiation of light so as to allow the residual photopolymerizable component to react.
SOLUTION: A data image is stored to an optical medium 14 by the interference of coded signal beams 20 and reference beams 22. A hologram is produced by the interference, and the hologram is trapped in the medium as a pattern of variable refractive indices. While irradiating a matrix of the medium with light, one or more photopolymerizable components are polymerized, and then after irradiation, the medium is fixed to obtain the permanent hologram. By this method, different from a conventional medium containing a perforated matrix, Bragg detune caused during forming the hologram or Bragg detune due to the temp. change are small so that the life on the recording face of the recorded hologram or fidelity of recording can be improved.
