CNET GLOSSARY: Terms for the techie
A DVD standard for recording and rewriting data used for computer storage. DVD-RAM drives can use single-sided (4.7GB) or double-sided (9.4GB) rewritable discs. They can also read and write older 2.6GB/5.2GB DVD-RAM discs. One drawback to DVD-RAM drives, however, is sluggish performance compared to DVD-R/RW and DVD+R/RW drives. Also, movies burned on DVD-RAM media are playable on only a very few drives and home players.
