The Nintendo GameCube Game Disc is a Nintendo-developed proprietary optical disc media for the GameCube. It is based on a variation of the 8 cm DVD, or MiniDVD. The optical disc holds 1.5 GB of information, and a barcode located on the inner ring of the disk surface assists in disc verification, helping to prevent software piracy.

Though the Nintendo GameCube Game Disc could hold quite a bit of information for its time, games which used a lot of voice work or FMV frequently needed to be placed on two discs, such as Metal Gear Solid: The Twin Snakes.
