TEAC has 4 divisions:
TEAC is known for its audio equipment, and was a primary manufacturer of high-end audio equipment in the 1980s. During that time, TEAC produced notable tape decks, cd players, turntables and amplifiers.
Of particular note is that TEAC produced an audio cassette with tape hubs reels that resembled reel-to-reel tape reels in appearance. Many manufactures of the time used these TEAC cassettes in advertisements of their tape decks because the TEAC cassettes looked more professional than standard audio cassettes, and because reel-to-reel tape recordings were known to be of higher quality than cassette recordings.
