Co-extruded multilayer optical data storage media (Conference Presentation)

Multilayer optical data storage is a promising approach for realizing high-capacity media with terabyte capacity for applications in enterprise archival data storage. We report on optical media containing 16 layers from a high-scalable multilayer polymer film co-extrusion process. Static and dynamic test data are presented as well as accelerated lifetime data, both indicating long shelf life. Other performance data such as threshold writing response, read stability presented. The data writing physics within the one-photon absorption spectrum is also presented. The impact of media lifetime, capacity roadmap and drive backward compatibility and on the economics of long-term archival storage is described.
