DVD±R (also DVD+/-R, "DVD plus/dash R", or "DVD plus/minus R") is not a separate
DVD format, but rather is a
shorthand term for a
DVD drive that can accept both of the common recordable DVD formats. Likewise,
DVD±RW (also written as DVD±R/W, DVD±R/RW, DVD±R/±RW, DVD+/-RW, and other arbitrary ways) handles both common rewritable
disc types (but not usually
DVD-RAM).
