Camcorders in the context of Secure Digital

Videotape is magnetic tape used for storing video and usually sound in addition. Information stored can be in the form of either an analog or digital signal. The tape can come in stand-alone tape reel or inside a casing such as a tape cartridge or cassette. Videotape is used in both video tape recorders (VTRs) and, more commonly, videocassette recorders (VCRs) and camcorders. Videotapes have also been used for storing scientific or medical data, such as the data produced by an electrocardiogram.

Because video signals have a very high bandwidth, and stationary heads would require extremely high tape speeds, in most cases, a helical-scan video head rotates against the moving tape to record the data in two dimensions.

MiniDVD or 8 cm DVD (also "3 inch DVD") is a DVD disc with a reduced diameter of 8 centimetres (3.15 in). It has been most commonly used in camcorders due to its compact size. 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. 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.
