Authenticity and Trustworthiness

UDO provides absolute data authenticity for regulatory compliance or for any application where archived information must remain 100% unchanged. UDO uses a patented Phase Change recording process that permanently alters the molecular structure of true Write Once media, ensuring data integrity at the most fundamental level. UDO is also available with
Rewritable media for archive environments where data needs to be deleted or media capacity reused. Unlike true Write Once media, Rewritable media allows the Phase Change recording process to be reversed. Enhanced error correction algorithms and read-ahead defect management complement UDO's Phase Change recording process to guarantee
unparalleled data integrity.

Long-term Data Retention UDO has been designed to provide decades of dependable data retention. A highly stable recording surface, carefully engineered protective coating and rock-solid cartridge delivers media life in excess of 50 years, minimizing the frequency of data migration and virtually eliminating media maintenance. The UDO drive design is robust and reduces the potential for contamination, enabling it to withstand the rigors of continuous, long-term use.

High Capacity and Scalability

Rapidly growing archive data volumes demand solutions with high initial capacity and flexibility to scale over time. Blue laser technology gives 30GB UDO more than three times the capacity of previous generation MO (Magneto Optical) and DVD technologies. The emovability of UDO cartridges, combined with the off-line media management capabilities of optical storage libraries, means scalability is essentially unlimited. Rarely used data can be removed from a library, freeing up capacity yet remaining managed and accessible.


Rapid Information Access

Knowledge assets are useless if they cannot be accessed when needed. UDO has fast 25-millisecond random access capability, facilitating timely retrieval of relevant data. An 8KB sector size optimizes read/write performance across a wide range of file sizes. UDO realizes additional performance by operating at Constant Angular Velocity (CAV). During both reads and writes the media spins continuously at the highest possible rate. In rewritable applications, UDO features a unique direct overwrite capability, doubling rewrite speeds by eliminating the need for a dedicated erase pass.


Low Total Cost of Ownership

UDO has a highly competitive archival storage TCO. With attractively priced 30GB media, the acquisition cost of a UDO library compares favorably with much less reliable tape or DVD solutions and costs a fraction of hard disk-based systems. UDO's ISO standard 5.25 inch media cartridge permits the use of MO and UDO media in the same library, eliminating
the necessity for migration from 9.1 MO media. Planned introductions of backward-compatible 60GB and 120GB UDO drives guarantee investment protection and minimize future migration expense. UDO drives and media are designed for longevity, and drives operate only when a cartridge is inserted - keeping overall maintenance and operating costs extremely low. Combined with its inherent authenticity and trustworthiness over time, outstanding capacity
and scalability, and excellent random access attributes, UDO's low TCO makes it the ideal solution for professional archive applications and a key element of a comprehensive information life cycle strategy.
