— DVD is the optical disc standard that replaced the CD. On a regular (single-layer, single-sided) DVD disc, about 4.7 GB of information is standardly placed — almost 7 times more than on a CD. Because of this capacity, DVDs gained popularity as media for movies and games, for which the capacity of CDs was no longer sufficient. Such media are also used for music — in the DVD-Audio format, which also significantly exceeds the previous CD-Audio in quality.The RW index denotes a rewritable disc: information can be repeatedly written and erased to such a medium. However, this category does not include all rewritable DVDs, but only media created using the original DVD-RW technology — a development of the DVD-Forum organization based on Pioneer technology. An alternative and more advanced option is DVD+RW. For more details, see the relevant paragraph, but here we note that the difference between these technologies is noticeable mainly with frequent rewriting: a DVD-RW disc must be completely erased before writing new data, while this is not required for DVD + RW. In addition, in "minus" media, the probability of errors is somewhat higher, but this moment, again, is noticeable only with frequent use or when recording numerous discs.
