Abstract

PURPOSE:To record and reproduce information with good quality by superposing two disks with information recording layers opposed after applying the faying surfaces between a spacer and the disks with adhesives curable by ultraviolet- ray irradiation, and then curing them by the ultraviolet-ray irradiation after leaving them until the thicknesses of the adhesive layers on the faying surface become uniform. CONSTITUTION:On transparent acrylic resin disks 1a and 1b, discoidal recording layers 2a and 2b of Te, etc., are formed. When the disks are superposed with the layers 2a and 2b opposed, an Al-made ring spacer 3 is interposed between the disks 1a and 1b, and the faying surfaces of the disks 1a and 1b are coated with adhesive 4 curable by ultraviolet-ray irradiation. Then, this united body is held horizontally on a table 5 and after it is left in a room intercepted from ultraviolet rays until the thicknesses of the adhesive 4 become uniform, the adhesive is stuck by being irradiated with ultraviolet rays from an ultraviolet-ray source 6. Thus, the mutual parallelism of the disks 1a and 1b is excellent and the recording body is free of undulation and strain.
