When Was The Videotape Invented?

The earliest type of realistic specialized videotape machines known as the Quadruplex machines, were also called Quad machines. The Quadruplex or Quad machines were introduced by Ampex in the United States of America in the year 1956.

The Quadruplex or Quad videotapes employed a transverse system which had four heads, which meant that the Quadruplex or Quad could be used by scanning the tape across the width of the videotape. The tape measured only about two inches, which means that they were approximately 5.08 centimetres long.

Quadruplex or Quad videotapes also have linear heads for the soundtrack. The British Broadcasting Corporation, which is abbreviated as the BBC, experimented with the use of a high-speed linear videotape system, which was called VERA. It was not feasible, as it had a half-inch (or 1.27 centimetres) long tape which travelled at a speed of about 200 inches (or about 5.08 metres) per second.
