Optical Disc Archive
Optical Disc Archive (ODA) is an archival storage technology developed by Sony. A single cartridge is designed to hold as many as 12 optical discs, each of which are similar to, but not directly compatible with, Blu-ray or Blu-Ray-BDXL systems, with total capacities per cartridge as high as 5.5 TB. Fabrication of the optical discs is licensed to TDK but primarily fabricated and developed by Sony and Panasonic.
