Nintendo optical discs

The GameCube Game Disc is a 1.46 GB,[6] 8 cm miniDVD-based[7] technology which reads at a constant angular velocity (CAV).

[4][11] Some GameCube games with large amounts of data span two discs, such as Resident Evil 4, Baten Kaitos, and Tales of Symphonia.

Full-motion video (FMV) scenes and audio clips have higher compression or lower quality to fit on a single disc.

[15][16] Upon that release, Nintendo admitted that some Wii systems may have trouble reading dual-layer discs due to a dirty laser lens.

[16][17] Nintendo repaired systems with dual-layer problems,[16][18] and later released a disc cleaning kit for users to purchase.

[clarification needed] 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".

There are also six additional evenly spaced small cuts, visible with a strong light source, located just outside the BCA radius, which are related to the copy-protection.

[26] Their value as a copy protection mechanism diminished after Datel discovered that the same pattern could be recorded into the DVD instead of needing to be precisely cut later.
