Frequency-Modulation Noise in Magnetic Recording

Abstract

Certain noise effects associated with high-frequency recorded signals are attributable to rapid fluctuations in the speed of the magnetic tape as it passes over the recording heads. The high-frequency tape flutter may be caused by resonant longitudinal vibrations which are excited by random frictional forces. The flutter rate can be determined theoretically from a consideration of the mechanical properties of magnetic tape, and the calculations verified by actual measurement with a frequency discriminator and spectrum analyzer.
