Roll-to-Roll Fabrication of Multilayer Films for High Capacity Optical Data Storage

摘要

Optical data storage (ODS) has led to transformative advances in information storage and distribution technology. Conventional two-dimensional ODS media have allowed storage capacities necessary for high-definition video. The capacity is limited, however, by the size of the disk and the number of layers that can be addressed using highly scattering phase-change materials employed in these media. Here we report on a co-extrusion process for fabricating roll-to-roll multilayer (ML) films for high-density ODS.
