Encyclopedia > Video Cassette Recording

Video Cassette Recording (VCR) was a video format by Philips, the first successful home videocassette recorder system. Koninklijke Philips Electronics N.V. (Royal Philips Electronics N.V.), usually known as Philips, (Euronext: PHIA, NYSE: PHG) is one of the largest electronics companies in the world. ... The videocassette recorder (or VCR, more commonly known in the British Isles as the video recorder), is a type of video tape recorder that uses removable videotape cassette containing magnetic tape to record audio and video from a television broadcast so it can be played back later. ...

The VCR format appeared at around the same time as the Sony U-matic. Although at first glance the two may have appeared to be competing formats, they were aimed at very different markets. U-matic was introduced as a professional format, whilst VCR was targeted particularly at educational but also domestic users. Sony Corporation (Japanese katakana: ソニー) (TYO: 6758 , NYSE: SNE) is a global Japanese consumer electronics corporation based in Tokyo, Japan. ... U-matic is the name of a videocassette format developed by Sony in 1969. ...

Home video systems had existed prior to this, but they were based on open reel systems and were extremely expensive to both buy and operate. The VCR system was still expensive by today's standards: the N1500 recorder cost nearly £600 in the United Kingdom when it was introduced in 1972, the equivalent of more than £4500 today. The pound sterling is the official currency of the United Kingdom (UK). ... 1972 (MCMLXXII) was a leap year that started on a Saturday. ...

The VCR format used large cassettes with 2 co-axial reels, one on top of the other, containing half inch wide chrome dioxide magnetic tape. Three playing times were available: 30, 45 and 60 minutes. The 60-minute cassettes proved very unreliable, suffering numerous snags and breakages due to the very thin tape. The mechanically complicated recorders themselves also proved somewhat unreliable. One particularly common failing occurred should tape slack develop within the cassette; the tape from the top (takeup) spool may droop into the path of the bottom (supply) spool and become entangled in it if rewind was selected. The cassette would then completely jam and require dismantling to free clear the problem, and the tape would be creased and damaged. Image File history File links N1500. ...

Magnetic tape is a non-volatile storage medium consisting of a magnetic coating on a thin plastic strip. ...

The system predated the development of the slant azimuth technique to prevent crosstalk between adjacent video tracks, so had to use an unrecorded guard band between tracks. This gave the system a comparatively high tape speed of around 11.5 inches per second. Helical Scan, or striping is a method of recording higher bandwidth signals onto magnetic tape than would otherwise be possible at the same tape speed with fixed heads. ... A guard band is a small part of the radio spectrum in between radio bands, for the purpose of preventing interference. ...

The VCR system brought together many advances in video recording technology to produce the first truly practical home video cassette system. It evolved into a longer-playing VCR-LP format (the N1700 player could not play N1500 tapes; they had to be recorded again), and an even longer SVR Super Video variant (by Grundig exclusively), before being replaced by Video 2000.

Video 2000 (or V2000; also known as Video Compact Cassette, or VCC) was a consumer VCR system and videotape standard developed by Philips and Grundig AG to compete with JVCs VHS and Sonys Betamax video technologies. ...

Video 2000 was also known as 'Video Compact Cassette' (VCC). Due to the similar initialisms, and the fact that both were designed by Philips, the 'VCC' and 'VCR' formats are often confused. However, the two systems are incompatible, and there are significant differences between them. Some Video 2000 machines carry the same "VCR" logo as N1500 and N1700 machines, adding further to this confusion. It has been suggested that this article or section be merged with Apocopation. ...

The videocassette recorder (or VCR, more commonly known in the British Isles as the video recorder), is a type of video tape recorder that uses removable videotape cassette containing magnetic tape to record audio and video from a television broadcast so it can be played back later.
Many VCRs have their own tuner (for direct TV reception) and a programmable timer (for unattended recording of a certain channel at a particular time).
DVD Video Recorders and Digital video recorders such as TiVo have recently begun to drop in price in developed countries, which some consider to be the writing on the wall for VCRs in those markets.
Videotape - Wikipedia, the free encyclopedia (1001 words)
In virtually all cases, a helical scan video head rotates against the moving tape to record the data in two dimensions, because video signals have a very high bandwidth, and static heads would require extremely high tape speeds.
Video tape is used in both video tape recorders (VTRs or, more common, video cassette recorders (VCRs)) and video cameras.
The first domestic videocassette recorders were launched in the early 1970s, but it was not until the Japanese systems, Sony's Beta (1975) and JVC's VHS, were launched, that videotape moved into the mass market, resulting in what came to be known as the "format wars".
