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. But there are variants that hold up to 5.2 GB.

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[edit]

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.
