ABSTRACT Bonding of a protection sheet on the substrate of the information- storage disk is made by revolving the substrate and the protection film with viscose adhesive applied therebetween, to spread it by centrifugal force, and after slowing down the rotation speed, UV-light is irradiated through the protection film to harden the adhesive. This enables controlled application of the adhesive without formation of bubbles, etc., and easy removal of excess adhesive from the edge of the disk.
