или описание ленты АБЕХ (явно указано через коррекцию 70мкс - лента хром):
"Signals on the tape: 12.5k, 10k, 6.3k, 1k and 250Hz
Level: -24dB (@0dB=250nWb/m) or -20dB (@0dB=160nWb/m)
IEC (Prague) 1981 standard
Time constant: 70us
This is a full track frequency response alignment tape, you can also use it for azimuth alignment as well.
The signals from 6.3k to 12.5kHz are ideal for azimuth check. The tape is almost not used before, no level drop off.
