From Wikipedia, the free encyclopedia.
A DVD-R is an optical disc with a larger storage capacity than a CD-R, typically 4.7 GB instead of 700 MB, although the original capacity of the standard was 3.95 GB. In the recording industry, they are used to record movies in better quality than a VHS tape. A DVD-R can be written to only once, whereas a DVD-RW is rewritable.
The DVD-R format was developed by Pioneer in autumn of 1997. It is supported by over 90% of today's DVD players, and is approved by the DVD Forum.
A competing format is DVD+R (also DVD+RW for the rewritables). Hybrid drives that can handle both formats, often labeled DVD±RW are very popular since there is no universal standard yet for recordable DVDs.
