Ultra Density Optical (UDO): Plasmon is developing Ultra Density Optical (UDO) with expected release in Q3, 2003. UDO is the next generation 5.25' professional optical storage technology. It is a convergent technology that delivers the performance of 5.25' MO, the longevity of 12-inch WORM, and the cost effectiveness of DVD. It utilizes blue-violet laser and phase change media recording technology from DVD consumer products to provide a quantum leap in data storage densities. First generation UDO products will be 30GB capacity, future generations will increase capacity to 60GB and 120GB and will provide full backward read compatibility. Both WORM and rewritable media will be available and the cartridge will be physically identical to 5.25” MO to maintain library compatibility. Target markets include archiving, document imaging, call centers, e-mail archiving, GIS, medical, telecom, banking, insurance, legal and government.
