Many DVD standalone players and recorders do not work with DVD-RAM. However, within "RAMPRG" (the DVD-RAM Promotion Group consisting of Hitachi, Toshiba, Maxell, LG Electronics, Matsushita/Panasonic, Samsung, Lite-On, Teac) there were a number of well-known manufacturers of standalone players, recorders, and camcorders that could use DVD-RAM.
This list includes both CD, DVD and Blu-ray recordable and rewritable media manufacturers (like Ritek), and disc replicators (companies that replicate discs with pre-recorded content, like Sony DADC).
HD DVD-RAM was the proposed successor to DVD-RAM for random access on optical media using phase-change principals. It would hold 20 gigabytes per layer instead of 15 gigabytes for HD DVD-R, due to differences in recording methods used, yielding a higher density disc.
DVD recorder drives can be used in conjunction with DVD authoring software to create DVDs near or equal to commercial quality, and are also widely used for data backup and exchange. As a general rule, computer-based DVD recorders can also handle CD-R and CD-RW media; in fact, a number of standalone DVD recorders use drives designed for computers.
Most DVD-authoring applications focus exclusively on video DVDs and do not support the authoring of DVD-Audio discs. Stand-alone DVD recorder units generally have basic authoring functions, though the creator of the DVD has little or no control over the layout of the DVD menus, which generally differ between models and brands.
While there is a HD-DVD variant that acts as a successor for the DVD-RAM, the HD DVD-RAM, a "BD-RAM" has never been released. Although the BD-RE has unrestricted random writing access capabilities, its rewrite cycle count of around 1000 times [ 17 ] is much lower than the potential 100,000 rewrite cycles of some DVD-RAM variants.
Currently, users can only record in VR mode with the use of DVD-RW, DVD-RAM and DVD+RW discs, (updated in 2000 to accommodate DVD-R (General)) [DVD players marked “RW compatible” and “DVD Multi” can play DVD-VR recorded discs] and on some recorders, also on hard-disk drives. Blu-ray Disc and HD DVD also support VR mode-like features.
This aims to be a complete list of DVD manufacturers. This list may not be complete or up to date. If you see a manufacturer that should be here but isn't (or one that shouldn't be here but is), please update the page accordingly. This list is only a list of brand names for DVDs and not an actual manufacturers list.
