History of Home Videotape Recorder Development
Yuma Shiraishi · SMPTE Journal · 1985
This article gives an overview of the development of home videotape recorders, from the early days to today's improved devices. Video technology is increasingly viewed as a necessity both for recording and also as an information-transfer medium through prerecorded cassettes. Starting with the appearance in 1956 of the quadruplex VTR, areas discussed include the two-head helical scanning system, the performance of today's oxide tapes and heads, chrominance signal recording, operability, the cassette format, and the key requirement of long playing time. The continuing development of the video systems and the new techniques engendered are investigated.
