Abstract: The present invention relates to a structure of optical disks fabricated by pasting two substrates together using an adhesive composed of thermo-setting resin and UV-curing resin and to a process for fabricating the said optical disks. Ceramic layers are formed in the inner and outer circumference parts but neither recording layer nor reflective layer is formed in the said parts so that UV-light can penetrate into the adhesive. Therefore, the two substrates can be temporarily fixed by irradiating them with UV-light because the UV-curing components of the adhesive in the inner and outer circumference parts hardens thereby. The optical disk temporarily fixed is heated to harden the thermo-setting components of the adhesive, thereby the substrates being perfectly pasted together. The temporal fixing of the substrates using UV-curing resin has such effects as that the substrates can be set upright, and therefore no strain occurs in the substrates, and that the adhesive does not overflow.
