UDO features blue laser technology to achieve far greater data densities, resulting in dramatically higher media capacities. First generation UDO media has a capacity of 30GB, with a roadmap extending to 60GB and 120GB in future generations.

UDO media is available in Write Once (True Write Once and Compliant Write Once) and Rewritable media formats. Each of the three media types has its own physical and operational properties making it well suited for different service levels within an overall archive strategy. Since UDO drives and Plasmon optical libraries support all media types, organizations can match the media format with the specific demands of each document class.

Rewritable UDO media is typically used in archive applications where the stability and longevity of optical media are important, but records change frequently and there is a need to delete and rewrite information. UDO Rewritable media is ideal for small office and departmental applications or in larger unstructured archives that are not subject to specific regulatory or corporate standards.

True Write Once media offers the highest level of physical record authenticity and is ideal for document classes with very long or indefinite record retention periods. Common uses of True Write Once media include medical, financial, industrial and cultural applications that require documents be retained for years or decades and must be held to a very high standard of legal admissibility.

Compliant Write Once media has the same operational properties as True Write Once UDO media with the ability to shred expired records for document classes that demand physical disposal. Designed specifically to assist organizations in meeting regulations on data retention and disposition while managing corporate risk, Compliant Write Once media can be used in a wide range of financial, administration and legal applications.

UDO media uses a patented and field-proven Phase Change recording technology that produces a very stable recording surface with a media life in excess of 50 years. Since it is a non-contact, non-magnetic recording process, data written on UDO media does not degrade with use, tolerates a wide range of temperature and humidity conditions and is insensitive to magnetic field exposure.

In order to protect UDO media from physical damage and contamination (dust, fingerprints, etc.), the disk is enclosed in a rugged ISO standard 5.25 inch cartridge. A unique double-shutter design prevents dust accumulation on the top surface of the media during recording. Lower dust contamination means more reliable read and write operations and extended media life.

UDO media has been certified by ISO, IEC and Ecma International. The "ECMA-350" UDO media standard was published in December 2003 and adopted by ISO/IEC in July 2004 as "International Standard ISO/IEC 17345". The Ecma Standard can be downloaded free of charge on the Ecma International website. The standard is also available free of charge on the ITTF (ISO/IEC Information Technology Task Force) website.

Plasmon manufactures UDO media in the United Kingdom and has granted a license to Mitsubishi Kagaku Media (MKM) for manufacturing second-source media in Japan. MKM's media products are sold under the Verbatim brand in North America, Europe and Asia and the Mitsubishi brand in Japan.
