It utilizes a design based on the Magneto-optical disc, but uses Phase Change technology combined with a blue violet laser.
Because its beam width is shorter when burning to a disc than a red-laser for MO, a blue-violet laser allows more information to be stored digitally in the same amount of space.
[2] It was later adopted with heavy investment by Plasmon, a UK technology company with extensive experience with computer archival backup systems and solutions.
The table below summarizes the differences between conventional Magneto-Optical specifications and those of the enhanced Ultra Density Optical disc.
UDO systems use a blue-violet laser operating at a wavelength of 405 nm, similar to the one used in Blu-ray Disc, to read and write data.
A company called Blu-Laser Cinema announced in June 2005 that it was launching a new player using the UDO format to provide a secure viewing and editing platform for film production houses.
[8] The core technology for UDO is essentially similar to Blu-ray Discs, as well as PDD (all were developed by Sony), although there are a number of key differences; the primary ones being:
