MiniDVD

From Free net encyclopedia

There are two types of MiniDVD.

cDVD, which are 80-mm versions of the 120-mm DVD
mini-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 Portable.

cDVD

Image:Mini-DVD-RAM with Holder.jpg cDVD or 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 inches.

Mini DVD-R/-RW media is available and is marketed for use in some newer DVD-based camcorders that record directly to the 80mm DVD disc. Typically these cameras offer more than one quality setting, with the highest quality offering 30 minutes of recording time per disc.

mini-DVD

mini-DVD was also used to describe a CD that contained DVD data written onto it. The mini-DVD data uses DVD formatting on a compact disc, with all the features of the DVD format. The difference between them is the physical disc itself. However, these CDs could only be played on DVD players, not VCD players. Since two discs were needed for the length of video held on one VCD, mini-DVD never gained popularity. Mini DVD was to be used on the Nintendo Ultra 64 but then was decided to continue with cartridges. However, Nintendo switched to a disc-based format for their next system, the GameCube, which was a variant of an 8cm DVD.
