A type of optical disk technology similar to the CD-ROM. DVD consists of two sides made of plastic which are stuck together. These sides are also called layers. Data can be pressed at a far higher density on both layers than on a CD, giving the DVD a considerably greater storage capacity. DVDR stands for DVD Recordable and DVDRW for DVD Rewriteable. A DVD holds a minimum of 4.7GB of data, enough for a full-length movie. A recordable DVD stores up to 2 hours of very good quality DVD-Video, including several audio tracks. DVDs are commonly used as a medium for digital representation of movies and other multimedia presentations that combine sound with graphics. The DVD specification supports disks with capacities of from 4.7GB to 17GB and the DVD specification supports access rates of 600KBps to 1.3MBps. DVD-ROM describes DVDs used as computer storage. DVD-R is a once-recordable DVD format, which requires a special drive and media, while such formats as DVD-RAM, DVD-RW, and DVD-R/RW can be written multiple times.
