PURPOSE:To allow the initialization of recording layers at the time of adhesion by forming an adhesive agent layer of a resin which is cured by light of the same wavelength as the wavelength of the stimulating light of the recording layers in the case of adhering plural optical recording media formed with the recording layers consisting of a photochromic material. CONSTITUTION:The optical memory element has optical disks 6, 7. The disks 6, 7 consist of transparent substrates 1, 5 and the recording layers 2, 4 provided on one surface thereof. The recording layers 2, 4 are formed of the photochromic material consisting of di-(2,3,5-trimethyl-4-thienyl)maleic anhydride (stilbene deriv.), etc. The disks 6, 7 are disposed in such a manner that the recording layers thereof face each other. These disks are adhered to each other by the adhesive agent layer 3 consisting of the photosetting resin. An acrylate adhesive agent, such as polyester acrylate, contg. 4,4'-bis(diethylamino)benzophenone: benzophenone (2:8), etc. as photoinitiator, is used as the adhesive agent. |
