About UDO

Designed for organizations seeking secure retention of important information, UDO succeeds 5.25 inch MO (Magneto Optical) technology as the new professional optical storage standard. UDO breaks the mold for optical storage solutions with increased storage capacity and dramatically lower archival storage costs.

UDO features blue laser recording rather than the red lasers used in previous optical drives such as MO and DVD. Blue lasers achieve far greater data densities, resulting in dramatically higher media capacities.

UDO media is packaged in an ISO standard 5.25 inch cartridge, allowing UDO and MO media to be supported in the same libraries, and reducing the cost of existing media migration.

The Phase Change recording technology used by UDO is field-proven and highly stable. With absolute authenticity and a media life of 50+ years, UDO meets the most demanding requirements of regulatory agencies and other authorities for the secure, long-term storage of information.

True Write Once media is list-priced at $60 per 30GB cartridge
