Video tape recorder in the context of "U-matic"

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.

CV-2000 was one of the world's first home video tape recorders (VTR), introduced by Sony in August 1965. The 'CV' in the model name stood for 'Consumer Video' (消費者向けビデオ, shōhishamuke bideo). This was Sony's domestic format throughout the 1960s. It was the first fully transistorized VCR.

The CV-2000 was developed by Sony engineer Nobutoshi Kihara. On its release, the CV-2000D machine was listed for US$695—equivalent to $6,935 in 2024—while a portable version in a more durable case, the CV-2000, was listed for $730—equivalent to $7,284 in 2024. It used 1⁄2-inch-wide (13 mm) video tape in a reel-to-reel format, meaning the tape had to be manually threaded around the helical scan video head drum. The CV-2000 was one-tenth the weight and price of other analog video recording products of its era. It recorded television programs in black and white using the skip field process, which produced a maximum 200-lines resolution. The tape moved at a speed of 7.5 inches per second. Two different reels were marketed: A reel of video tape listed for about US$22—equivalent to $220 in 2024—had 30-minute playtime, and video-tape reel listed for about US$40 could hold one hour of video. Although CV-2000 was aimed at the home market, it was mainly used in business and educational institutions.

Helical scan is a method of recording high-frequency signals on magnetic tape, used in open-reel video tape recorders, video cassette recorders, digital audio tape recorders, and some computer tape drives.

With this technique, magnetic tape heads (or head chips) are placed on a rotating head drum, which moves the chips at high speed by due to its high angular velocity. The speed of the head chips must be higher than the linear speed of the tape. The tape is wrapped tightly around the drum. The drum and/or the tape is tilted at an angle that allows the head chips to read the tape diagonally. The linear speed of the tape is slower than the speed of the head chips, allowing high frequency signals to be read or recorded, such as video. As the tape moves linearly or length-wise, the head chips move across the width of the tape in a diagonal path. Due to geometry, this allows for high head chip speeds, known as writing speeds, to be achieved in spite of the low linear speed of the tape. The high writing speed allows for high frequency signals to be recorded. As each head chip enters into contact with the tape, it creates or reads long and narrow areas with information recorded magnetically known as tracks. In Helical scan, these tracks are positioned diagonally, relative to the length of the tape. The diagonal tracks read or written using this method are known as helical tracks.

VHS (Video Home System) is a discontinued standard for consumer-level analog video recording on tape cassettes, introduced in 1976 by JVC. It was the dominant home video format throughout the tape media period of the 1980s and 1990s.

Magnetic tape video recording was adopted by the television industry in the 1950s in the form of the first commercialized video tape recorders (VTRs), but the devices were expensive and used only in professional environments. In the 1970s, videotape technology became affordable for home use, and widespread adoption of videocassette recorders (VCRs) began; the VHS became the most popular media format for VCRs as it would win the "format war" against Betamax (backed by Sony) and a number of other competing tape standards.

A hard disk recorder (HDR) is a system that uses a high-capacity hard disk to record digital audio or digital video. Hard disk recording systems represent an alternative to reel-to-reel audio tape recording and video tape recorders, and provide non-linear editing capabilities unavailable using tape recorders. Audio HDR systems, which can be standalone or computer-based, are typically combined with provisions for digital mixing and processing of the audio signal to produce a digital audio workstation (DAW).

Direct-to-disk recording (DDR) refers to methods which may also use optical disc recording technologies such as DVD, and Compact disc.

Nam June Paik (Korean: 백남준; July 20, 1932 – January 29, 2006) was a South Korean artist. He worked with a variety of media and is considered to be the founder of video art. He is credited with the first use (1974) of the term "electronic super highway" to describe the future of telecommunications.

Born in Seoul to a wealthy business family, Paik trained as a classical musician, spending time in Japan and West Germany, where he joined the Fluxus collective and developed a friendship with experimental composer John Cage. He moved to New York City in 1964 and began working with cellist Charlotte Moorman to create performance art. Soon after, he began to incorporate televisions and video tape recorders into his work, acquiring growing fame. A stroke in 1996 left him partially paralyzed for the last decade of his life.
