Was there a life before the Audio CD or how else they wrote digital sound MORE


Once upon a time, when there were no lovers of warming up cables and installing “power harmonizers” , and soundtrack players were all analog, very noisy and almost always monophonic, the harsh Japanese engineers from the city of Tokyo came to the conclusion that it’s enough to endure this and it’s time, finally, to explore new horizons, at the same time combining business with pleasure - a dream to show a huge cookie pot for gaijins . Since the advantage in the field of video recording by the 60s was already firmly entrenched in the Americans (grandfather Ponyatoff in 1956 released the world's first video recorder Ampex VR-1000, which instantly buried the telekino ; a little later the Soviets pulled up), it was decided to develop the unknown then Another direction of digital sound recording. And here just the development of pale-faced ones turned out to be very useful - after all, few people now remember that for many decades in a row, huge reel video recorders with rotating heads were almost the only devices capable of providing the highest data recording density per square centimeter, and at the same time to develop such a speed of reading the signal that no punch cards could even dream of - it was about megahertz of the useful frequency range, given from the magnetic tape every second.
