(Ultra Density Optical) An optical disc technology developed by Plasmon and later acquired by Alliance Storage Technologies (www.alliancestoragetechnologies.com), UDO is used for long-term data archiving. Available in both rewritable and write-once (WORM) 5.25" media, UDO uses blue laser optics and phase change recording. Introduced in 2003 with a 30GB capacity, storage was doubled to 60GB in 2007, and media life is expected to exceed 100 years.Although similar to the rewritable CD/DVD drives used by consumers, UDO was designed with more robust engineering for commercial applications. For example, rewritable UDO uses eight layers in the disc compared to the typical four in consumer media.Where Magneto-Optic StoppedDesigned to supersede magneto-optic (MO) disks in capacity, UDO's first blue laser 30GB drives offered a big storage jump over 9.1GB, the final format for MO drives. See blue laser, phase change disk, PDD and magneto-optic disk.
A perennial plant (Aralia cordata) native to East Asia, having bipinnately compound leaves and young shoots that are cooked and eaten as a vegetable.
