Method of making a master disk used in making optical readable information disks |
摘要 |
A method of manufacturing an optical master disk, matrix derived from the master disk and synthetic resin information disk derived from the matrix. A method of manufacturing an optical master disk in which a supporting plate is provided on one side with at least two layers of a photosensitive material in which, taken from the supporting plate, the photosensitivity of the material of the layers increases and/or in which a light-absorbing separation layer is used between the layers, as well as a metal matrix derived from the master disk and an optically readable information disk of synthetic resin derived from the matrix.
