DVDRW

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.
