MiniDVD or 8 cm DVD (also "3 inch DVD") is a DVD disc with a reduced diameter of {{convert|8|cm|in|2}}. It has been most commonly used in camcorders due to its compact size.{{Cite web |date=2005-02-06 |title=Kid Vid and the Mini-DVD |url=https://www.soundandvision.com/news/020405minidvd |access-date=2023-12-14 |website=Sound & Vision |language=en}} 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.
8 cm DVDs were originally used for music videos and as such became known as DVD single, similarly to how 8 cm optical discs were previously used for music singles on compact discs (i.e. CD single and miniCD). However the MiniDVD format has been mostly used as recordable discs in DVD-based camcorders during the 2000s; a single layer disc can record up to 30 minutes of standard definition video.{{Cite news |last=Biersdorfer |first=J. d |date=2005-02-24 |title=On Only 3 Inches of Disc, 30 Minutes of High-Quality Video |language=en-US |work=The New York Times |url=https://www.nytimes.com/2005/02/24/technology/circuits/on-only-3-inches-of-disc-30-minutes-of-highquality.html |access-date=2023-12-14 |issn=0362-4331}} A number of movies and TV shows have also been released on the format in the mid-2000s, usually targeting children using low-cost small players.
Nintendo used a very similar disc-based format for the GameCube.
MiniDVD capacities
The most common MiniDVDs are single layered, which can hold 1.46 GB of data, however, there also exists dual layered 2.6 GB versions,{{Cite web |title=Mini DVD+R DL 2.6GB 2.4X Branded 3pk Jewel Case |url=https://www.duplication.ca/Mini-DVD-R-DL-2.6GB-2.4X-Branded-3pk-Jewel-Case.html |access-date=2023-01-14 |website=Duplication.ca|date=4 January 2008 }} dual sided single layer 2.8 GB versions,{{Cite web |title=Maxell Mini DVD-RAM VIDEO 60 Minute 2.8 GB |url=https://www.duplication.ca/maxell-mini-dvd-ram.html |access-date=2023-01-14 |website=Duplication.ca|date=28 February 2019 }} and dual sided dual layer 5.2 GB versions. A double sided MiniDVD can hold 2.8 GB of data (1.4 GB x 2), however, a dual-layer MiniDVD can only hold 2.6 GB of data due to the limitations when manufacturing dual layered discs. A double sided dual layered disc can hold 5.2 GB of data (2.6 GB x 2), with the MiniDVD-RAM version of the double sided, dual layer disc being able to hold 5.6 GB of data (2.8GB x 2).
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).
