Method and apparatus for manufacturing optical memory devices |
摘要 |
A method and apparatus for manufacturing an optical memory device. The method comprises the steps of forming a secondary medium layer on a substrate and forming on the substrate guide track grooves for guiding a light beam, both steps being carried out in a single vacuum chamber. The step of forming the guide track grooves comprises heating the substrate to soften the same and pressurizing the substrate by a pressure roller having transcribed patterns corresponding to the guide track grooves on its cylindrical surface.
