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).

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
