<P>PROBLEM TO BE SOLVED: To provide an optical memory capable of enhancing reproducibility of recorded information in reproduction. <P>SOLUTION: The optical memory 10 is constituted by laminating a plurality of optical waveguides 17. Each optical waveguide 17 comprises a core layer 13 and clad layers 14 laminated on and under the core layer 13 and a rugged part for reproducing information is formed on one interface between the core layer 13 and the clad layers 14. The core layer 13 and the clad layers 14 are formed by using UV curable resin. The UV curable resin used for the core layer 13 has ≤6% shrinkage. Since film thickness fluctuation generated at the core layer when the resin is irradiated with UV to be cured is suppressed, a BER (Bit Error Rate) in reproducing recorded information can be reduced and reproducibility of recorded information is enhanced. <P>COPYRIGHT: (C)2007,JPO&INPIT |
