![]() A rewritable DVD disc is a media which allows rewriting many times. It will have functions and applications similar to those of floppy discs or MO (magneto-optical) discs and a large capacity (2.6GB or more for a single side). It willbe an efficient rewritable medium for handling and storing data which requires large capacity, such as moving pictures. For writing on a disc, a DVD-RAM(rewritable) drive connected to a computer is required.Because ultra-precise writing is necessary, even a fingerprint left on a writing side of a disc before writing would change the optical intensity so that accurate writing could not be achieved. Therefore, a DVD-RAM(rewritable) disc will be contained in a special cartridge. When the content of the disc is DVD-Video, it will be possible to play back the disc on a DVD player or a DVD personal computer in the same way as playback of DVD-R(write-once) discs. The specifications of a rewritable disc have not yet been finalized, and it will be a while before rewritable(DVD-RAM) discs, including the necessary writing equipment, become available. |
