The MiniDVD is also known as a "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 are single layered and 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 dual 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.
