DVD authoring is the process of creating a DVD video capable of playing on a DVD player. DVD authoring software must conform to the specifications set by the DVD Forum . DVD authoring is the second step in the process of producing finished DVDs.
Optical disc authoring, including CD, 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).
Modern compact discs support a writing speed of 52× and higher, with some modern DVDs supporting speeds of up to 24×. [4] Writing a DVD at 1× (1 385 000 bytes per second) [5] is approximately 9 times faster than writing a CD at 1× (153 600 bytes per second). [6] However, the actual speeds depend on the type of data being written to the disc ...
DVD+R, DVD+RW and the recordable Blu-ray formats are immune from buffer underrun as these discs contain technology that allows the recorder's write mechanism to precisely locate the end of the recorded track and to seamlessly carry on from where it left off. Many disc authoring utilities disable the buffer underrun protection option when these ...
Some half-height DVD Multi Recorder drives released since 2007, such as the TSSTcorp SH-S203/TS-H653B (2007) have officially adapted support for writing speeds of up to 12× on DVD-R DL and 16× on DVD+R DL (on recordable media by selected vendors only), while more recent DVD writers such as the SH-224DB (2013) and Blu-ray writers such as the ...
DAO recording is also the only way to write data to the unused R-W sub-channels. This allows for extended graphic and text features on an audio CD such as CD+G and CD-Text. It is also the only way to write audio files that link together seamlessly with no gaps, a technique often used in progressive rock, trance and other music genres.
The purpose of LightScribe is to allow users to create direct-to-disc labels (as opposed to stick-on labels), using their optical disc writer. Special discs and a compatible disc writer are required. Before or after burning data to the read-side of the disc, the user turns the disc over and inserts it with the label side down.
Recorders use a laser (usually 650 nm red) to read and write DVDs. The reading laser is usually not stronger than 5 mW, while the writing laser is considerably more powerful. The faster the writing speed is rated, the stronger the laser. DVD burner lasers often peak at about 100-400 mW in continuous wave (some are pulsed).
