Mitsubishi Kagaku Media/Verbatim, Memory Tech Corporation, and Plasmon have announced that they've developed a new optical storage format called UDO-DMD, or Ultra Density Optical - Digital Master Disk. Based on blue laser UDO technology, UDO-DMD was designed for secure distribution and long-term storage of HD DVD content.
Mitsubishi Kagaku Media (MKM)/Verbatim, Memory Tech Corporation (MTC), and Plasmon today announced a technology and business alliance to manufacture and promote a new optical storage format called UDO-DMD (Ultra Density Optical - Digital Master Disk). UDO-DMD has been designed specifically for the secure distribution and long-term storage of high value HD DVD content between authoring studios and disc mastering facilities.

Based on professional blue laser UDO technology, DMD drives and media have been optimized to meet the stringent security and reliability requirements of the HD DVD content industry. Many studios today depend on magnetic tape and RAID systems to transport and archive valuable content. Video content is often lost on tapes because they are fragile for transport and unreliable for long-term storage, and managing rapidly growing data on RAID is insecure and cost prohibitive for archives that must be maintained for many years. By contrast, UDO-DMD provides an extremely stable media housed in a robust cartridge that has a data life far greater than tape or RAID storage. To minimize the risk of content piracy, the new DMD media cannot be written and read in standard UDO drives. DMD also provides physical WORM (Write Once Read Many) recording for content authenticity and an additional cartridge locking security feature to minimise the risk of valuable content loss.
According to the press release, DMD will initially be released with a 30GB capacity, growing to 60GB in the second quarter of 2007. More information on DMD can be found here.
