Non-recordable formats

DVD-ROM: These are pressed similarly to CDs. The reflective surface is silver or gold colored. They can be single-sided/single-layered, single-sided/double-layered, double-sided/single-layered, or double-sided/double-layered. As of 2004, new double-sided discs have become increasingly rare.

DVD-D: Self-destructing disposable DVD format introduced in 2008. Like EZ-D, it is sold in an airtight package, and begins to destroy itself by oxidation after several hours.

DVD Plus: combines both DVD and CD technologies by providing the CD layer and a DVD layer. Not to be confused with the DVD+ formats below.

Recordable formats, supported by the DVD Forum

DVD-R for Authoring: a special-purpose DVD-R used to record DVD masters, which can then be duplicated to pressed DVDs by a duplication plant. They require a special DVD-R recorder, and are not often used nowadays since many duplicators can now accept ordinary DVD-R masters.

DVD-R (strictly called DVD-R for General): can record up to 4.7 GB in a similar fashion to a CD-R disc. Once recorded and finalized it can be played by most DVD-ROM players.

DVD-RW: can record up to 4.7 GB in a similar fashion to a CD-RWdisc.

DVD-R DL: a derivative of DVD-R that uses double-layer recordable discs to store up to 8.5 GB of data.

DVD-RW DL: a derivative of DVD-RW that uses double-layer recordable discs to store up to 8.5 GB of data.

DVD-RAM (current specification is version 2.1): 2.6 GB, 4.7 GB or 9.4 GB (double-sided) discs compatible with only a small proportion of other-format DVD drives. DVD-RAM discs were originally typically housed in a cartridge, though these are now less commonly required. Discs can be removed from their caddy and used in compatible standard-tray drives. Rewritable many more times than other rewritable formats.

DVD-AR: Recordable version of DVD-Audio

Recordable formats, supported by the DVD+RW Alliance

DVD+R: can record up to 4.7 GB, at up to 16× speed. As with DVD-R it can only be recorded on once.

DVD+RW: can record up to 4.7 GB at up to 16× speed. Since it is rewritable it can be overwritten several times. It does not need special "pre-pits" or finalization to be played in a DVD player.

DVD+R DL: a derivate of DVD+R that uses dual-layer recordable discs to store up to 8.5 GB of data.

DVD+RW DL: a derivate of DVD+RW that uses dual-layer recordable discs to store up to 8.5 GB of data.
