Reference excerpt

TEAC Corporation (ティアック株式会社, Tiakku Kabushiki-gaisha) () is a Japanese electronics manufacturer. TEAC was created by the merger of the Tokyo Television Acoustic Company, founded in 1953, and the Tokyo Electro-Acoustic Company, founded in 1956.

Overview

TEAC is known for its audio equipment, and was a primary manufacturer of high-end audio equipment in the 1970s and 1980s and low-end audio during the 1990s. During that time, TEAC produced reel-to-reel machines, cassette decks, CD players, turntables and amplifiers. TEAC produced an audio cassette with tape hubs that resembled reel-to-reel tape reels in appearance. Many manufacturers at 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.

History The company that eventually became the TEAC corporation was founded in August 1953. Originally named the Tokyo Television Acoustic Company, it employed Katsuma Tani, a former aviation and aeronautics engineer, who established a reputation as a highly qualified creator of audio equipment. In 1956, his brother, Tomoma Tani, brought home a hand-made, 3-motor, 3-head stereo tape recorder. This sparked Katsuma's interest in reel-to-reel tape recorders. Confident they could engineer a better tape recorder, the Tani brothers founded the Tokyo Electro-Acoustic Company on 24 December 1956. The Tokyo Television Acoustic Company and the Tokyo Electro-Acoustic Company were merged to create the TEAC corporation, taking the initials of the latter company as its name. The main focus of the new company was to design and manufacture tape recorders. In 1969, TEAC produced the first consumer four-track reel-to-reel tape recorders capable of playing pre-recorded Quadraphonic open reel tapes (Q4). This was the first format to play high quality four-channel quadraphonic recordings in the home. In order to keep costs affordable, home machines used slower tape speeds and narrower track widths compared to similar professional machines. Quadraphonic sound was not widely adopted by the public and the Q4 format died by the late 1970s. In 1972, TEAC introduced the first consumer grade four-track reel-to-reel recorders with Simul-Sync that were capable of overdubbing. Musicians were able to use these products as the basis of home recording studios. With this advancement many consumers created sophisticated home demo recordings for the first time. TEAC, and its TASCAM division, as well as other manufacturers sold thousands of these machines to musicians well into the 1990s. Some of TEAC's most popular home multitrack recorders with Simul-Sync:

The A3340 4-track recorder with 10.5" tape reels, 7½ and 15 ips speeds w/ manual direction toggle lever The A2340 4-track recorder with 7" tape reels, 3¾ and 7½ ips speeds w/ manual direction toggle lever The A3340S 4-track recorder with 10.5" tape reels, 7½ and 15 ips speeds, the 's' designation indicates an improved tape transport mechanism with solenoid control The A2340S 4-track recorder with 7" tape reels, 3¾ and 7½ ips speeds, the 's' designation indicates an improved tape transport mechanism with solenoid control In 2013, Gibson bought a majority stake in the company, giving it 54.42% of the company. After Gibson's bankruptcy in 2018, TEAC announced that they would continue to operate on their own.

Computer tape memory systems In May 1961, TEAC entered into a licensing agreement with IBM to create magnetic tape memory systems.

TEAC Australia TEAC Australia were established in 1978 and licensed the TEAC brand name to distribute rebadged electronics manufactured by generic electronics manufacturers in China, or by companies such as GoldStar and Funai. These products were sold in discount department stores such as Kmart and had a reputation for being cheap and poor quality.

Worked examples

Example 1 — a first encounter with TEAC Corporation

Start with the simplest possible case. Write down what TEAC Corporation claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to TEAC Corporation before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about TEAC Corporation ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of TEAC Corporation

In research: TEAC Corporation appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses TEAC Corporation in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: TEAC Corporation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Audio equipment manufacturers of Japan, Companies based in Tama, Tokyo, Companies listed on the Tokyo Stock Exchange, so understanding it makes those chapters shorter.
In everyday life: Look for TEAC Corporation outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
