The first video
recordings were actually made by john Logie Baird in 1928, using
gramophone discs which were fed through his Televisor.
But the
use of tape did not appear until 1956, when Alexander Poniatoff
demonstrated his Ampex machine in Chicago - and used it for a
pre-recorded television broadcast as well.
Within
two years, RCA announced their video-recorder, but in 1967 Ampex
developed a video recording system which used a metal disc
rather than a reel of tape, which was able to locate and play
back any part of a program in less than four seconds - the
beginning of “instant replay” as on television sports programs.
There
are three system in use at the moment for home use - the VHS
system, developed by Sony, the Beta system developed by Sanyo
(both of Japan), and the “2000” system developed by Philips, of
Holland and Britain.
Laser vision, also a Philips development, while technically more
advanced than any, can only play-back and not record on a home
video machine, so has not been so successful.
