Latest Patents

Fujisaku's latest patents focus on a manufacturing method and apparatus for optical discs. The method involves creating a transparent disc substrate with two relatively wide-area surfaces, where information is recorded. A first reflective film is formed on a dummy disc that has similar surfaces, and a second reflective film with light semi-transmissive characteristics is also created. These components are bonded via an adhesive layer. An external force is then applied to peel off the dummy disc at the interface between the dummy disc and the second reflective film. In a preferred embodiment, partial peeling is achieved through mechanical force, while complete peeling is facilitated by supplying compressed air to the interface.
