About DVD+RW/+R

DVD+RW/+R is the leading format for consumers storing video, music, images and data to DVD discs. The benefits of DVD+RW/+R include: the capability of recording up to 4.7 gigabytes of digital video, images, music or data -- this equates to the storage capacity of nearly seven CD-R/RW discs and the potential to store thousands of digital photographs or approximately two hours of digital video; two-way compatibility that allows DVD+RW and DVD+R discs to be played in most DVD-video players and DVD-ROM drives in use today; and support for write-once DVD+R capability, which protects information from being accidentally changed or deleted.

How is DVD+RW related to DVD-RAM and DVD-RW?

DVD+RW, DVD-RAM and DVD-RW are all rewritable DVD formats, however, only DVD+RW is designed from the start to be compatible with existing DVD-ROM drives and DVD-Video players, both on a physical as well as a logical level. This means that a DVD+RW disc recorded in a DVD+RW video recorder can be played in virtually all DVD-Video players or DVD-ROM equiped PCs, and that any DVD+RW disc recorded with data on a PC DVD+RW drive can be read by most DVD-ROM drives.

DVD+RW birth

DVD+RW was announced in 1997, but bringing the standard to fruition took longer than anticipated. The original capacity in the 1997 spec was for 3.0GB discs, but delays in delivering products allowed the companies to shift to a full 4.7GB per surface (which is the same capacity as single-sided/single-layer data or video DVDs). Note that most DVD capacity specs are listed as GB, when in fact they are referring to billions of bytes. We'll just specify GB as do most sources to avoid even more confusion, with the implicit assumption the reader knows it's really billions of bytes.
