Optical Disc Archive is a proprietary storage technology that was introduced by the Sony Corporation. It uses removable cartridges, where each cartridge holds 11 optical discs. Each of the internal optical discs is similar to, but not compatible with, a Blu-ray disc. The latest version of the cartridge, that has a total capacity of about 5.5TB, uses discs that hold about 500GB each.[1] The technology was publicly announced [2] on 16 April 2012 during the NAB Show with the first units shipping in February 2013.
