DVD
writers are also named DVD burners and DVD writers. In the beginning of
DVD history, DVD recorders supported one of those three formats or standards: DVD-RAM, DVD-RW using DVD-VR, and DVD+RW using DVD+VR.
None of those DVD formats were directly compatible. As a general rule in
the industry, however, almost all current DVD writers support both the +
and - standards, while few support the DVD-RAM standard that is not directly compatible with standard DVD readers.
DVD writer's recording speed is generally denoted in values of X, similar to
marking CD-ROM specifications, where 1X in DVD usage is equal to 1.321 MB/s,
equivalent to a 9X CD-ROM.
