Three heads: one record, one playback, and one erase head.
Tape width and head configuration allow stereo recording and playback on quarter-track tape.
Tape Transport and Motors
Three motors:
One hysteresis synchronous capstan motor for precise tape speed control.
Two 6-pole winding reel motors for stable tape tension and smooth winding.Tape speeds: 9.5 cm/s (3¾ ips) and 19 cm/s (7½ ips) with ±0.5% speed accuracy.
Wow and flutter (synchronization fluctuations): less than 0.10% at 9.5 cm/s and less than 0.08% at 19 cm/s.
Rewind speed: approximately 90 seconds for 370 meters of tape.
Frequency Response and Sound Quality
Frequency response:
40 Hz to 12 kHz ±3 dB at 9.5 cm/s (3¾ ips)
