Abstract:
1. A method for producing optical disk including a first substrate and a second substrate in which a signal area is to be formed on one principal plane, comprising the processes of: (i) fixing the other principal plane of the second substrate, which is an opposite side of the one principal plane, to a support; (ii) forming at least one film selected from a metal film, a dielectric film, a magnetic film and a coloring film on the one principal plane; (iii) forming at least one film selected from a metal film, a dielectric film, a magnetic film and a coloring film on the one principal plane; (iv) attaching the first substrate and the second substrate to each other with the at least one film interposed therebetween; and (v) releasing the other principal plane of the second substrate from the support, wherein the processes are performed in an order of (i), (ii), (iii), (iv), and (v).
