<p>A process for making at least a single-faced, write and/or read optical disk having a sub-layer with a smooth or high-resolution featured surface and an opaque, substantially flat substrate includes the steps of interjecting between the opaque, substantially flat substrate (44) and a transparent, highly polished or featured master mold (46), a thin layer of viscous composition (48) which is radiation-curable to a solid plastic without undergoing significant shrinkage. The layer of viscous composition (48) is irradiated through the transparent master mold (46) to cure the composition to a solid plastic sub-layer having the desired smooth or high-resolution featured surface. After irradiation of the composition, the master mold (46) is removed, leaving the cured plastic sub-layer adhered to the substrate (44). The substrate (44) is preferably metal, such as aluminum, and the master (46) is preferably glass with an etched featured surface thereon.</p> |
