From Wikipedia, the free encyclopedia.
A DVD+R is a writable optical disc with 4.7 GB of storage capacity. The format was developed by a coalition of corporations, known as the DVD+RW Alliance, in mid 2002. Although DVD+R has not yet been approved by the DVD Forum, DVD+R discs are playable in 87%-95% of today's DVD players.
In October of 2003, it was demonstrated that dual layer technology could be used with a DVD+R disc to nearly double the capacity to 8.5 GB per disc. Manufacturers are expected to incorporate this technology into commercial devices sometime during 2004.
Unlike DVD+RW discs, DVD+R discs can be only be written to once. Because of this, DVD+R discs are suited to applications such as nonvolatile data storage, audio, or video.
One competing format is DVD-R. Hybrid drives that can handle both, often labeled "DVD±RW, are very popular since there is not yet a single standard for recordable DVDs.
