MiniDVD

MiniDVD (also Mini DVD or miniDVD) is a DVD disc which is 8 centimetres (3.15 in) in diameter. It refers two separated formats as well. One is a pseudo-format that uses 80mm CD-R(W) to store contents with the same structure as the standard DVD-Video so that standalone DVD players can play it like standard DVD. The other format is a real DVD format, but in a smaller 80mm size, which holds 1.4 GB of data (there are also variants that can hold up to 5.2 GB).

This article is about 8 cm DVDs. For other uses, see MiniDVD (disambiguation).

Optical discs

The 8 cm optical disc format was originally used for music CD singles, hence the commonly used names CD single and miniCD. Similarly, the manufactured 8 cm DVDs were originally used for music videos and as such became known as DVD single.

MiniDVD is known also as "3 inch DVD", referring to its approximate diameter in inches.

MiniDVD capacities

Recordable 8 cm discs are commonly used in DVD-based camcorders. The most common MiniDVDs hold 1.4 GB of data, but there are variants that can offer up to 5.2 GB of storage space, through a combination of dual layers and sides. Mini DVDs are also available in +R, +R DS, +R DL, +R DL DS, +RW, +RW DS, -R, -R DS, -R DL, -R DL DS, -RW, and -RW DS variants, just like their full sized counterparts. (DL=Double Layer, DS=Double Sided)

Variants of MiniDVD

Nintendo used a disc-based format for their GameCube system, which is a variant of an 8 cm DVD. This format is also supported by the pre-RVL-101 models on the Wii for backward compatibility with the GameCube.

gollark: Just subtract one from all years. I don't think that could go wrong at all.

gollark: You could generally just put it in code blocks, unless you prevent that somehow.
