The invention is directed towards techniques for creating optical data storage disks. In one embodiment, the invention provides a simultaneous two-sided rolling bead process. For example, a method may include positioning a first bead of photopolymer for distribution between a bottom stamper and a substrate, and positioning a second bead of photopolymer for distribution between a top stamper and the substrate. The method may also include passing a roller over the top stamper to distribute the beads of photopolymer, curing the photopolymer, and removing the substrate from the stampers. The simultaneous two-sided rolling bead process can be repeated on the same medium to create a two-sided dual-layer data storage medium or a two-sided multi-layer data storage medium. |
