Abstract:

The document discusses the means for reproducing electrical ultra-low frequency signals from a magnetic tape which make it possible to use ordinary recording devices for the registration of these signals without difficulties, and to use ordinary electromagnetic heads for their reproduction. The use of electrical modulation techniques is considered, permitting the use of ordinary magnetic recorders with rather weak specifications for the reproduction of electrical ultra-low frequency signals.
