.jpg)     A video tape recorder (VTR), is a tape recorder that can record video material. When video recording was first invented, video was recorded onto individual tape reels, as were audio recordings. Loading a videotape reel required threading of the tape through rollers and across recording and playback heads onto a takeup reel. Reel-to-reel recorders have inherent problems of tape damage from hand-threading, tape media contamination due to threading with bare hands, and an exposed tape path contaminated by dust. The video cassette recorder (VCR), where the videotape is enclosed in a user-friendly videocassette shell, is the most familiar type of VTR known to consumers. The tape is pre-attached onto two reels enclosed within the cassette, and tape loading and unloading is automated. There is no need for the user to ever touch the tape, and the media can be protected from dust, dirt, and tape misalignments that could foul the recording mechanism. Typically the only time the user ever touches the tape in a videocassette is when a failure results in tape getting stuck in the mechanism.

[edit] History of video tape recording2 inch quadruplex (also called 2″ quad, or just quad, for short) was the first commercially successful videotape format. It was developed and released for the broadcast television industry in 1956 by Ampex, an American company based in Redwood City, California. This format revolutionized television broadcast operations and production, since the only medium available to the TV industry before then was motion picture film used for kinescopes, which was much more costly to utilize and took more time to develop. Home VCRs first became available in the early 1970s — such as a Philips VCR model, released in 1972. The first system to be successful with consumers was Sony's Betamax in 1975. This was quickly followed by the competing VHS (Video Home System) format from JVC, and later by Video 2000 from Philips. Subsequently, the Betamax-VHS format war began in earnest. Other competitors, such as Sanyo's V-Cord and Quasar's "Great Time Machine" quickly disappeared. Beta sales soon dwindled away in the US and Europe and VHS emerged as the winner of the format war. In 1988, Sony began to market their own VHS machines, and despite claims that they were still backing Beta, it was clear that the format was dead - at least in Europe and the U.S. In parts of South America and in Japan Beta continued to be popular and was still in production up to the end of 2002.
