DVD-RW is a rewritable format that is closely related to DVD-R, and is recorded by similar drives. DVD-RW is a sequential read/write media primarily designed for video recording and streaming computer backup applications. Verbatim DVD-RW discs are manufactured with a patented phase change Super Eutectic Recording Layer (SERL) which minimizes optical noise during erase/rewrite cycles, and provides superior archival life. DVD-RW discs can be rewritten over 1,000 times. A number of DVD-ROM drives and DVD Video players support DVD-RW.
