There are two types of
80 mm DVD,
which are smaller versions of the 120 mm DVD
which are standard CDs written with the DVD-video format
The name is also sometimes used
erroneously to refer to the Universal Media Disc
(UMD), the format used by Sony's PlayStation
80 mm DVD
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, but like its full-sized 120-mm
counterpart, it can be played back in most DVD players.
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.
cDVD are also known as '3-inch
DVDs' in reference to their approximate diameter in
Mini DVD-R/-RW media is
available and is 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 by varying the bitrate: XP (20 minutes), SP (30 minutes),
and LP (60 minutes).
A Single Sided Dual Layer form
of this media, stated to hold 2.66 GB, has been planned for release near
the end of 2006.
Nintendo used a disc-based format for their
GameCube system, which was a variant of an 80-mm DVD.
Mini DVD is also the brand name
of a line of commercial DVDs and players released by Warner and CyberHome
and intended for a young audience.
mini-DVD or cDVD is also used to
describe a CD that contains DVD data, allowing all the features of the DVD
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 Megabytes, whereas other CD-based video
formats such as SVCD use the Mode 2/XA format and can store roughly 800
Megabytes of data per 80 minute CD.
