A '''DVD+R''' is a writable [[optical disc]] with 4.7 [[gigabyte|GB]] (4.38 [[gibibyte|GiB]]) of [[computer storage|storage capacity]] (interpreted as <math>\approx 4.7\cdot10^9</math>, actually 2295104 sectors of 2048 [[byte]]s each). The format was developed by a coalition of corporations, known as the [[DVD plus RW Alliance|DVD+RW Alliance]], in mid [[2002]]. Since the DVD+R format is a competing format to the [[DVD-R]] format which is developed by the [[DVD Forum]] it has not been approved by the DVD Forum which claims that the DVD+R format is not an official DVD format.

In October of [[2003]], it was demonstrated that [[Dual_layer|double layer]] technology could be used with a DVD+R disc to nearly double the capacity to 8.5 GB per disc. Manufacturers have incorporated this technology into commercial devices since mid-[[2004]] (see [[DVD_plus_R_DL|DVD+R DL]]).

Unlike [[DVD plus RW|DVD+RW]] discs, DVD+R discs can only be written to once. Because of this, DVD+R discs are suited to applications such as nonvolatile data storage, audio, or video.

The DVD+R format is divergent from the [[DVD-R]] format. Hybrid drives that can handle both, often labeled "[[DVD±R|DVD±RW]]", are very popular since there is not yet a single standard for recordable DVDs. There are a number of significant technical differences between the ''dash'' and ''plus'' formats, and although most consumers would not notice the difference, the ''plus'' format is considered by some to be [http://www.cdfreaks.com/article/113 better engineered].

Like other ''plus'' media, it is possible to use [[Book_type|bitsetting]] to increase the compatibility of DVD+R media.

As of [[2005]], the market for recordable DVD technology shows little sign of settling down in favour of either the ''plus'' or ''dash'' formats, which is mostly the result of the increasing numbers of dual-format devices that can record to both formats; it has become very difficult to find new devices that can only record to one of the formats.
