Nintendo optical discs are the optical disc format used to distribute video games released by Nintendo. This includes the Nintendo GameCube Game Disc, Wii Optical Disc, and Wii U Optical Disc. The physical size of a Nintendo GameCube Game Disc is that of a miniDVD, and the Wii and Wii U Optical Discs are the size of a DVD. GameCube discs can be used with the original version of the Wii and Wii Optical Discs can be used in the Wii U for backward compatibility. A burst cutting area is located at the inner ring of the disc surface.

Nintendo GameCube Game Disc

The Nintendo GameCube Game Disc (DOL-006) is the game medium for the Nintendo GameCube, created by Matsushita (Panasonic),[1] and later extended for use on the Wii through backward compatibility.[2] The GameCube Game Disc is a 1.5 GB,[3] 8 cm miniDVD based technology which reads at a constant angular velocity (CAV). It was chosen by Nintendo to prevent copyright infringement of its games,[4] to reduce cost[5][6] by avoiding licensing fees to the DVD Forum and to reduce loading times. This also limits the consoles from being used as general DVD players.[7][8]

One downside to the GameCube Game Disc is the relatively small storage; some games with large amounts of data had to be placed across two discs. Multi-platform games that fit on PlayStation 2 and Xbox DVD discs occasionally saw the removal of certain features in order to fit on GameCube Game Discs. Full-motion video scenes and audio are more compressed to fit on a single disc, reducing their quality. Prior to the Nintendo GameCube, Nintendo consoles traditionally used cartridge-based media.

Wii Optical Disc

The Wii Optical Disc (RVL-006) is the physical game medium for the Wii, created by Panasonic. Nintendo extended their proprietary technology to use a full size 12 cm, 4.7/8.54 GB DVD-based disc, enabling it to have the benefits of the Nintendo GameCube Game Disc, while having the standard capacity of a double-layer DVD-ROM. Although the Wii can use double-layer discs, all titles were single-layer prior to the release of Super Smash Bros. Brawl.[9][10] With the release of Super Smash Bros. Brawl, Nintendo admitted that some Wii systems may have trouble reading dual-layer discs due to a dirty laser lens.[10][11] Nintendo repaired systems with dual-layer problems,[10] and later released a disc cleaning kit for users to purchase.[12]

Wii U Optical Disc

The Wii U Optical Disc (WUP-006) is the physical game medium for the Wii U, with a capacity of 25 GB per layer. The Wii U system is backward compatible with Wii Optical Discs, but not backward compatible with Nintendo GameCube game discs.[13] The optical discs used for the Wii U differ in appearance from most other optical discs in that they have soft, rounded edges.[14]

The format was developed and supplied by Panasonic, which is one of the major patent holders in Blu-ray technology. It is not clear whether the Wii U Optical Disc is similar in physical design to the Blu-ray physical disc specification. Nintendo President, Satoru Iwata stated, "Wii U does not have DVD or Blu-ray playback capabilities. The reason for that is that we feel that enough people already have devices that are capable of playing DVDs and Blu-ray, such that it didn't warrant the cost involved to build that functionality into the Wii U console because of the patents related to those technologies."[15]:3

Burst cutting area

Each Nintendo optical disc contains a burst cutting area (BCA) mark, a type of barcode that is written to the disc with a YAG laser. The data stored in this BCA mark includes an encrypted table related to the hardware-based copy-protection mechanics, in addition to 64 bytes of un-encrypted user-accessible data.[16]

A BCA mark is visible to the naked eye. It should not be confused with the IFPI mark that is on all optical discs. BCA is described in Annex K of the physical specification, and can be seen between radius 22.3±0.4 mm and 23.5±0.5 mm. There are also six additional evenly spaced small cuts just outside the BCA radius, which are related to the copy-protection used. These small cuts can clearly be seen if the disc is held in front of a strong light source.[16]
