Multilayer optical data storage is a promising approach for realizing terabyte-capacity media for applications in enterprise archival data storage. We report on our highly scalable roll-to-roll co-extrusion manufacturing process for producing multilayer films with nanoscale active layers with easy fabrication into optical discs. We describe the optical pickup unit for dynamic testing at commercial speeds as well as results on writing and reading an eight-layer disc. Tests indicate that our materials are capable of high-fidelity recording with low, commercial-appropriate media noise. Prospects for commercialization of our technology for long-lived active-archive applications are described.
