Pre-recorded audio- and video-program DVDs are mass-produced with molding machines that stamp the data onto the disc. Such a disc is a read-only memory disc (DVD-ROM), because data can only be read (played back) and can neither be erased nor overwritten. Blank, recordable DVDs can be repeatedly recorded and erased. The DVD format is applied to DVD-Video and DVD-Audio consumer products, and for recording AVCHD discs. Moreover, when the DVD format solely stores informational data, it is denoted as a DVD data disc.
The DVD specification supports disks with capacities of from 4.7GB to 17GB and access rates of 600KBps to 1.3 MBps. One of the best features of DVD drives is that they are backward-compatible with CD-ROMs, meaning they can play old CD-ROMs, CD-I disks, and video CDs, as well as new DVD-ROMs. Newer DVD players can also read CD-R disks.
