VIDEO RECORDING
A video tape recorder is a complex integration of electronics and extremely high precision mechanics. There have been several types of recording systems in recent years, the main contenders being ‘Betamax’ from Sony, ‘Video 2000’ from Philips and ‘VHS’ from Matsushita. They are all based around a tape contained in a cassette with a supply spool and a take up spool. However, there were both electronic and mechanical differences that prevented on tape being used on another make. The one to emerge as the standard throughout the would is the VHS system. VHS means Video Home System and was developed by the JVC Company in Japan.
All video tape recorders follow the same principles as and audiocassette recorder. That is a tape containing thousands of tiny magnets, each with a north and south pole, is passed through a varying magnetic field. The magnetic field is generated in a revolving drum from the video signal. This reproduces the video image onto the tape.
