Abstract

To establish the high density disc system, the most important point is how discs are produced stably on high rate of yield. From the point of this view we developed a new laser cutting machine of master disc and a novel duplicator of replica disc. This cutting machine which is compactly designed has a improved optical system which are stabel against temperature fluctuation and other environmental disturbance. And we can produce high quality discs at high rate of index time by our disc duplicator using liquid photo-polymer resin which is cured by ultra-violet ray.
