Conventional 12 cm disc (left) compared to 8 cm disc (right)
MiniDVD (also Mini DVD or miniDVD) is a DVD disc which is 8 centimetres (3.15 in) in diameter. Most MiniDVDs hold 1.4 GB of data, but there are variants that hold up to 5.2 GB. The MiniDVD is also known as a "3 inch DVD", referring to its approximate diameter in inches.
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.
