摘要：
Reflection confocal readout was obtained by use of a recording medium in which photosensitive thin films and nonphotosensitive films are stacked alternately. For this purpose, a recording medium consisting of alternately stacked thin urethane-urea copolymer films and nonphotosensitive transparent polyvinyl alcohol (PVA) films was developed.
