Abstract: A multi-layered azobenzene polymer thin film layer (8) is formed on a substrate (1). Holograms are recorded on each of the azobenzene polymer thin films (1, 2, 3, 4, . . . ) of the azobenzene polymer layer (8) after forming two-dimensional surface reliefs by photoisomerization. To read the recorded information, infrared rays are irradiated from a laser source (9) through the selected azobenzene polymer thin films of the azobenzene polymer layer (8) via a cylindrical lens (10). The memory contents of the selected hologram (11) are read under visible light for reproduction. Wavelength conversion, amplification and other functions can be added. The optical waveguide type holographic memory of this invention also makes it possible to increase the memory capacity simply by lamination.
