Frequency-modulation magnetic-tape playback system

Data recording systems which make use of
frequency-modulation of a carrier signal recorded on
Magnetic tape are subject to noise resulting from speed
variations in the recording or playback mechanisms. This
report describes a playback system which reduces this
noise by utilizing a constant-frequency signal recorded
Simultaneously with the data signal, but on a different
channel of the tape, to obtain a measure of the speed
variations. By using this information, the system
reduces the noise to a fixed level which is independent
of the magnitude of the speed variations. This playback
system was designed for use in connection with Hardtack
Project 1.1 and was used in processing the magnetic tape
information obtained in the field. 2 references.
