During that time, TEAC produced reel-to-reel machines, cassette decks, CD players, turntables and amplifiers.
Originally named the Tokyo Television Acoustic Company,[3] it employed Katsuma Tani, a former aviation and aeronautics engineer,[4] who established a reputation as a highly qualified creator of audio equipment.
Confident they could engineer a better tape recorder, the Tani brothers founded the Tokyo Electro-Acoustic Company on 24 December 1956.
In 1972 TEAC introduced the first consumer grade four-track reel-to-reel recorders with Simul-Sync that were capable of overdubbing.
[8] In May 1961 TEAC entered into a licensing agreement with IBM to create magnetic tape memory systems.
