DVDRW Drive
DVDRW is a physical format for re-writable DVDs and can hold up
to 4.7 GB. DVD+RW was created by the DVD+RW Alliance, an industry
consortium of drive and disc manufacturers. Additionally, DVD+RW
supports a method of writing called "lossless linking", which makes
it suitable for random access and improves compatibility with DVD
players.

The capacity of a single-layer disc is approximated as 4.7 x 109
bytes. In actuality, the disc is laid out with 2295104 sectors of
2048 bytes each which comes to 4,700,372,992 bytes, 4,590,208
kilobytes (KiB, binary kilobytes), 4482.625 megabytes (MiB, binary
megabytes), or 4.377563476 gibabytes (GiB, binary gigabytes).
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
(i.e. DVD-R and DVD+R). Likewise, DVD±RW (also written as DVD±R/W,
DVD±R/RW, DVD±R/±RW, DVD+/-RW, and other arbitrary ways) handles
both common re-writable disc types
DVD+RW must be formatted before recording by a
DVD recorder.
