SONY

The name of SONY was coined as abstract, consonant with the English word Sound (sound) and Sonic (sound) and pronounced in all languages in the same way - SONY. SONY began in September 1945 when Masaru Ibuka founded Tokyo Tsushin Kenkyujo with a group of like-minded people. At first, the company was engaged in everything that turned up by the arm. In 1946, Ibuka expanded his business and took in partnership with his longtime friend Akio Morita. Masaru Ibuka wanted to produce things for a wide range of customers, it only remained to find the right product.
He turned his attention to a wire recorder. But the tape recorder made by him had a number of shortcomings: fast head wear, short recording time, high noise level, and Masaru Ibuka decided to make a tape recorder using a tape with a magnetic layer. The lion's share of the work on this project belonged to electronic engineer Kihara.

First of all, he took up the invention of magnetic tape manufacturing technology. The OP magnet powder was chosen as the material of the magnetic layer, but only noise and wheezing appeared in the phonogram, the head was not able to “register” the tape. And then almost by accident, Kihara decided to try the chemical ferroxide, and the tape sounded.

In 1950, the first C-type and A-type tape recorders appeared. With the invention of the first transistor by the American company RCA, Ibuka decided to make transistor receivers and tape recorders, but for this it was necessary to manufacture his transistors. After long negotiations, he managed to obtain a patent for the manufacture of transistors and in 1954 the first 2T14 transistors and 1T23 diodes were manufactured. In 1957, when the "era of silicon" came, Ibuka instructed one of the leading engineers at Tsukamote to study the possibilities of using transistors in television receivers.
A year later, the world's smallest black-and-white TV-301 appeared, where there were 23 silicon and germanium transistors, 50 conventional and two high-voltage diodes. On April 15, 1968, the first Trinitron television was developed.

In parallel with the transistor TV and Trinitron CRT, SONY was actively working on a video recording device. She became the first company to develop a video decoder using technology from the American company Ampex. SONY initiated the adoption of a single video standard. In 1970, SONY, Matsushita, JVC, and five other companies entered into a format unification agreement. The leader was the company SONY, which demonstrated in 1971 the new color cassette system U-matic and video players VP-1100 and VO-1700. SONY and JVC have developed new formats for compact camcorders: Video-8 and VHS Compact. The most widely used formats are Video-8 (Hi8) and (S-VHS-C).

In 1997, SONY developed a new technology for the production of picture tubes with an ultra-flat screen F.D. Trinitron (Flat Display - a flat display device). The first televisions to use this technology appeared under the name FD Trinitron WEGA (KV-29FX11). FDTrinitron technology includes four key achievements of the company's developers: an ultra-flat screen, the use of new materials to create a given tube strength, and an aperture grille with high quality centering and spotlight with improved focus.
