This was based on Fritz Pfleumer's 1928 invention of paper tape with oxide powder lacquered onto it. The first practical tape recorder from AEG was the Magnetophon K1, demonstrated in Berlin, Germany in 1935. Eduard Schüller of AEG built the recorders and developed a ring-shaped recording and playback head. It replaced the needle-shaped head ...
Before the invention of the video tape recorder, live video was recorded onto motion picture film stock in a process known as telerecording or kinescoping. Although the first quadruplex VTRs recorded with good quality, the recordings could not be slowed or freeze-framed , so kinescoping processes continued to be used for about a decade after ...
The first consumer videocassette recorders (VCRs) used Sony U-matic technology and were launched in 1971. Philips entered the domestic market the following year with the N1500 . [ 23 ] Sony's Betamax (1975) and JVC's VHS (1976) created a mass-market for VCRs and the two competing systems battled the videotape format war , which VHS ultimately won.

Instead, Kaku—a leading expert in the field of particle physics and string theory—wanted to draw attention to the coming revolution in quantum computing, which he argues in his latest book ...
In March 1957, Ampex won an Emmy award for the invention of the Video Tape Recorder (VTR). In 1958, NASA selected Ampex data recorders and magnetic tape. It has been used for virtually all U.S. space missions since. In 1959, the Nixon-Khrushchev Kitchen Debate was recorded on Ampex videotape. The fact that the debate was being videotaped was ...
