The Nintendo Wii Optical Disc was a proprietary DVD-based format used in the Nintendo Wii games console, introduced in 2006.
The format was created by Panasonic for Nintendo, and is a full sized version of the Nintendo GameCube disc, with the potential capacity of a double-layer DVD-ROM (most early discs were single-layer). The disc reader of the Wii does not play DVD-Video, DVD-Audio or Compact Discs.
The Wii Optical Disc uses a burst cutting area mark on the disc to store encrypted data for copy-protection.
The Wii was a seventh-generation game console, that competed with consoles such as the Microsoft Xbox 360, and Sony PlayStation 3. It introduced the Wii Remote controller, which can be used as a handheld pointing device and which detects movement in three dimensions. Early models were compatible with GameCube discs and with GameCube Memory Cards. Secure Digital cards can be used for uploading photos and backing up saved game data and downloaded Virtual Console and WiiWare games.
The Wii was replaced by the Wii U in 2012, and was discontinued in 2013.
