A disk for optical storage media is being embossed with information during the injection molding process on both sides. Using 2 such disks, a reflective coating is being applied on the front side of the first disk and a resin layer is being applied on said reflective coating. Then the back side of said second disk is being pressed into the resin layer to transfer the embossed information to the first disk. After separating said second disk from the first one the second disk is being used as first substrate in a subsequent process, thereby avoiding any waste stamper disk. |
