METHOD FOR FABRICATING DVD-COMPATIBLE HOLOGRAPHIC ROM DISK AND DISK STRUCTURE THEREOF

摘要

The present invention relates to a manufacturing method and a holographic disc structure of a DVD -compatible effective romyong holographic disk . In other words the present invention, in the holographic ROM disk manufacturing process compatible DVD , DVD compatible disc prior to bonding by the dichroic reflecting layer in the graphics alone installation disk to a holographic disk , data replication and ends at the same time the production of the holographic ROM disk completed step 2 , including the fixing DVD compatible holographic ROM disk manufacturing process can be reduced to a one-step process to increase the production yield by preventing the consumption alone gongjeonghwa graphic ROM disk at the time of data reproduction process generation process preceding the defective disk bonding process , can reduce the disk manufacturing costs .
