A Broadcast-Quality Video/Audio Recording System with VHS Cassette and Head Scanning System
Significant advances in magnetic recording technology in the 1970's made possible the development of a broadcast-quality video recording system based on the video home system (VHS) tape transport and cassette. The system, known as M-format, is the first multi-track, analog component video recording system introduced commercially. With a standard VHS cassette containing a standard-thickness tape, it records 20 min of video along with two high-quality audio channels and SMPTE longitudinal time code. This article discusses technical details of the recording system, signal format, and innovative circuit techniques employed.
