A 14-inch reel of 2-inch quad videotape compared with a modern-day MiniDV videocassette. Both media store one hour of color video. The first commercial professional broadcast quality videotape machines capable of replacing kinescopes were the two-inch quadruplex videotape (Quad) machines introduced by Ampex on April 14, 1956, at the National Association of Broadcasters convention in Chicago.
Subsequently, the video head erases and re-records the video signal (combined luminance and color signal) over the same tape surface, but the video signal's higher center frequency results in a shallower magnetization of the tape, allowing both the video and residual AFM audio signal to coexist on tape.
Not all video tape recorders use a cassette to contain the videotape. Early models of consumer video tape recorders , and most professional broadcast analog videotape machines (e.g. 1-inch Type C) use reel to reel tape spools. The history of the videocassette recorder follows the history of videotape recording in general.
A video tape recorder (VTR) is a tape recorder designed to record and playback video and audio material from magnetic tape. The early VTRs were open-reel devices that record on individual reels of 2-inch-wide (5.08 cm) tape.
Whichever container is used, the video itself is not re-encoded and represents a complete digital copy of what has been recorded onto tape. If needed, the video can be recorded back to tape to create a full and lossless copy of the original footage. Some camcorders also feature a USB 2.0 port for computer connection.

Digital8 is the most recent 8mm video format. It retains the same physical cassette shell as its predecessors, and can even record onto Video8 (not recommended) or Hi8 cassettes. However, the format in which video is encoded and stored on the tape itself is the entirely digital DV format (and thus very different from the analog Video8 and Hi8 ...
