April 14 marks 65 years since the day (1956) when the Ampex company, created by the Russian and American engineer Alexander Ponyatov (1892 – 1980), demonstrated in Chicago the first in the world
commercial video recorder VR-1000. Soon, the first recorded TV programs went on air in the United States. In less than six months, the device was used in all the leading television studios in the United States. IN
In 1961, Ampex and its head Ponyatov received an Oscar for their contribution to this technology.
Alexander Matveevich Ponyatov was born on March 25, 1892 in the village Russian Aisha of Kazan province in the family of a merchant of the first guild. After graduating from the First real school in Kazan A.M.
Ponyatov in 1909-1910 studied at Imperial Kazan University at the Faculty of Physics and Mathematics.
Then, due to his passion for aviation, he was transferred to Imperial Moscow Technical School (MVTU)… Fearing harassment by the authorities for participating in student
gatherings in Moscow, A.M. Poniatov moves to the city to study Karlsruhewhere he was educated in Higher Technical School… To study in Germany, he left with the recommendations of Professor N.E.
In 1913, he returned to Russia and was drafted into military service, graduated from a pilot school, a participant in the First World War. During the Civil War in 1918 – 1920 A.M. Poniatov served in the rank
lieutenant in the White Army, after the defeat of which he emigrated first to China, and then to France and the United States.
In 1932, he received American citizenship. First time worked in the company General Electricthen went to Pacific Gas and Electric, then – to the firm Dalmo-Victor
Westinghousedeveloping electrical equipment for aircraft.
A.M. Ponyatov also experimented with electronics in his garage and in 1944 he founded his own company. Ampex… She made electromechanical devices for precise tracking
drive radar antennas.
After the war, the activities of the company were reoriented to the development of magnetic sound recording devices. In 1947, a prototype Model 200A audio recorder was created and demonstrated in Hollywood.
Further, the company produces a number of successful models of tape recorders: Model 300 (1949); Model 400 (low cost, 1950) and Model 600 (portable device, 1954).
In 1951, Poniatov began to develop a video recording device using the principle of transverse line recording with rotating heads. This method made it possible to combine high speed
movement of the magnetic head relative to the tape, necessary to record a TV signal bandwidth of several MHz with a low speed of movement of the tape itself, acceptable for continuous recording on

using a magnetic tape of the Q format for recording a video signal.This product was an overwhelming success, and the company headed by Ponyatov for a long time was the world’s leading manufacturer
video tape equipment.
The VCR turned out to be only part of a large technological pyramid that Ampex had to create. To do this, it was necessary to develop a completely new video tape – thin, durable,
capable of interacting with a video head, the temperature of which at the point of contact with the magnetic tape reaches several hundred degrees.
At the same time, in the mechanics of the product, it was required to achieve micron accuracy, and in electronics – the use of new methods of signal processing. As a result, the video recorder actually turned out to be the most
complex serial radio-technical device of that time.
In 1959, the VRX-1000 video recorder was demonstrated at the American exhibition in Moscow. At this exhibition, N.S. Khrushchev was presented with a tape recording of his meeting with US Vice President Richard
Nixon, but in those days in the USSR there was simply nothing to see it. Therefore, the recording was simply sent to the archives of the All-Union Scientific Research Institute of Sound Recording (now VNIITR).
And later she came there and a package from Ampex with a photocopy of the diagrams and a full technical description of the VCR. Soon in the Soviet Union, the serial production of video recorders was launched.
