Additional Details


Bi-directional record and playback were the main selling point of the X-700R. It featured six Hard permalloy heads (two each for erase, record and playback) and three motors.
Speeds were 7½ and 3¾ ips and maximum reel size was 7″.
A dbx noise reduction circuit was incorporated, and, coupled with EE (Extra Efficiency) tape, the X-700R had a pretty impressive frequency response and signal to noise ratio.
A dual-capstan closed-loop transport mechanism was employed, which effectively isolated the tape in the critical head area from tension irregularities outside of the loop and hence reducing wow and flutter to a minimum (0.03%
at 7½ ips). A ±6% pitch control was also included.
Full logic control enabled direct switching between any mode and a record mute function and timer rec/play capability provided recording convenience.
