There are two types of MiniDVD.
The name is also sometimes used erroneously to refer to the Universal Media Disc ( UMD ), the format used by Sony's PlayStation Portable . 80 MM DVD with DVD Round Holder.]] MiniDVD ('''Mini DVD''' or '''miniDVD''') is an 80 mm diameter disc. In normal recording (standard DVD quality), it holds 30 minutes of video or 1.4 GB of data. Under SLP mode, comparable to VHS quality, it can hold 120 minutes of video. It was developed for use in camcorders, and like its full-sized 120 mm counterpart, can be played back in most DVD Player s. The format is also known as a video-single, or DVD Single , being analogous to the CD Single ( MiniCD ) in being a Singles format for music videos. MiniDVDs (80 mm) are known also as "3 Inch DVDs," referring to their approximate diameter in inches. Mini DVD-R/-RW media are available and are marketed for use in some newer, DVD-based camcorders that record directly to the 80 mm DVD disc. Typically, these cameras offer three quality settings in varying bitrates: XP (20 minutes), SP (30 minutes), and LP (60 minutes). They have also been known to be used for making duplicates of Gamecube Games . Although working out at around £ 1 (US$2) per gigabyte, they are aimed at the Camcorder market where they will nearly double the length of recording time but are also compatible with DVD players and drives that support dual layer media. Nintendo used a Disc-based Format for their GameCube system, which was a variant of an 80 mm DVD. Warner Mini DVD CDVD mini-DVD or '''cDVD''' is also used to describe a CD that contains DVD-Video data, allowing all the features of the DVD-Video format to be used on the cheaper medium. The difference between them is the physical disc itself. However, these CDs can only be played on computers or some standalone DVD players, not VCD players, and have only a fraction of the capacity of a DVD. Additionally, ''mini-DVDs'' must be written to CD using the Mode 1 format. This limits the amount of data that can be stored on an 80 minute CD to 700 MiB , whereas other CD-based video formats such as SVCD use the Mode 2/XA format and can store roughly 800 MiB of data per 80 minute CD.
