Optical disc authoring and modify files, without having to write the whole disc again. A compatibility technology called HighMAT allows visual material on the disc to be recognised, interpreted and supported by electronic play devices more efficiently. Optical disc authoring Optical disc authoring, including DVD and Blu-ray Disc authoring is the process of assembling source material—video, audio or other data—into the proper logical volume format to then be recorded ("burned") onto an optical disc (typically a compact disc or DVD). To burn an optical disc, one usually first creates an optical disc image with a full file system, of a type designed for
Ultra Density Optical Ultra Density Optical Ultra Density Optical (UDO) 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 (5.25") 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 80 GB. 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
