Ultra Density Optical - Bücher neu kaufen

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Ultra Density Optical is an optical disc format designed for high-density storage of high-definition video and data. An Ultra Density Optical disc or UDO is a 133.35 mm ISO cartridge optical disc which can store up to 30 GB of data. The second generation UDO2 media was introduced in April 2007 and has a capacity of up to 60GBs. Utilising a design based on a Magneto-optical disc, but using Phase Change technology combined with a blue violet laser, a UDO/UDO2 disc can store substantially more data than a magneto-optical disc or MO, because of the shorter wavelength of the blue-violet laser employed. MOs use a 650 nm-wavelength red 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.
