VHS

Description

VHS (Video Home System), which was introduced by JVC in 1976, is recommended as a reference or classroom viewing format and is not acceptable for public exhibition. A VHS cassette contains a 1/2-inch-wide magnetic tape wound between two spools, allowing it to be slowly passed over the various playback and recording heads of the video cassette recorder. The quality of a VHS tape degrades significantly after repeated playing, and when projected results in a substantially compromised image. As VHS was the consumer standard during the 1980s and 90s, a wide range of decks are still in circulation. Only professional models should be considered for playback; lesser decks are much more prone to "eating" tapes.
