Additional Details

Description

The RT-909,  an auto reverse / auto repeat-playback stereo tape deck produced from 1979 until 1984 , has four heads (erase, record and two playback).
The similar RT-901 did not feature auto-reverse and thus only had a single head (and a few less controls.)
Both recorders were rack-mountable and designed to take 10½ ” reels. A closed-loop dual capstan drive system isolated the tape at the heads from any external interference, which resulted in a constant tape-to-head
contact.
