In 1993, my friend gave me a wonderful birthday gifft! a book about Mr. Teragaki, Inventor, the man who designed legendary Seiko-Epson turntable.

I wanted to meet him, but back then Internet is not big in Japan. I contacted a machine shop who supported his turntable projects. The machineshop owner helpmed me to introduce to Mt.Teragaki. I visited his development shop couple of times in Tokyo. He was about 70 years old, but he was full of energy and joy!  

Audio Technica invested him over $3 million for his turntable development. Though, they decided not to market as a product. CD was there and $100K turntable was not practical at the time...

Audio Technica T1 (Design #7):
Vacuumed surface
auto disk centering 
linear tracking arm, the massive tonearm does not go up and down, the turn table does go up and down

In 1987,  Σ-3000 (Design #12) was sold for 2,300K JPY produced 30 (10 assembled, sold 6) units in1987
In 1994,  Σ-5000 was sold for 3,200K JPY (no compromise version of Σ-3000), produced 30 units
In 1997, Σ-5000 II was sold for 3,200K JPY
Σ-2000 released early 1990s for 1,400K JPY, produced 100 units (reduced cost version of Σ-3000)
The platter is 1.5 degree tapered to the center to eliminate warped disk. AND the platter is also tilted 1.5 degree. At the end platter is level where stylus covtact!


I still want to own his Σ-3000. I only saw and heard twice at his office in early 90's...
