About Ultra Density Optical 
UDO is a blue-laser-based optical media that offers permanent, authentic-WORM (Write Once Read Many) storage, rated to last more than 50 years. Rewriteable and Compliant Write Once media types are also available.  Unlike consumer market DVD and Blu-ray offerings, UDO is a commercial grade solution that maintains a ‘compliant’ data archive over a long period of time.  UDO’s unique material properties and hardened plastic encasement support media handling and removability without causing damage to the stored information.  

The UDO blue-laser process is one of the only technologies that ‘guarantees’ data integrity through verification of every write operation to the media. It offers excellent performance through random access of data, unlike streaming technologies used for video and music.  UDO’s 25-millisecond seek times are close to disk access speeds, yet have lower acquisition costs, use 15% of the power of disk and are much faster than tape and DVD. The media is water-proof and magnetic-proof and can be cleaned without losing data.  UDO is backward compatible with older UDO drives, preserving the usability of the media over long periods of time.
