Somewhat similar to DVD-R and DVD-RW, DVD+RW deals with issues of playback compatibility on different DVD players. A new standard, introduced late 2000, it was formed by an alliance of DVD manufacturers (Philips, Hewlett-Packard, Sony, Yamaha, Ricoh, Mitsubishi/Verbatim, Dell, RCA). By late 2001, nearly every other manufacturer has joined to adopt this new format. 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. Issues regarding backward and forward compatibility are pretty flexible. For the most part, a home recorded DVD+RW disc can be played in a DVD-Video player or DVD-ROM drive, and a DVD-Video disc can be played on a DVD+RW recorder. Tests have proven a re-recording capability of over 1,000 times on a DVD+RW disc. In recording and data storage applications, DVD+RW acts more like a hard-drive so you can store information in random packets and can add additional information even after a recording session has been completed (DVD-RW does not). Discs will be compatible for DVD+RW Computer Drives and DVD+RW Video Recorders
