This Austrian-made half-track mono recorder had three speed, 3¾ ips being the highest, hence the name Tricorder. It was very likely the first recorder to employ the ultra-slow speed of 15/16 ips, giving 12 hours continuous recording. Many were skeptical that a recording speed this slow could be successful, but apparently it was, even though a frequency response of only 40 – 4kHz 2dB was attainable.
However, the Tricorder boasted an exceptionally well-designed tape drive mechanism which gave a very low wow and flutter figure of 0.3% even at the lowest speed.
