Variable-Area Recording with the Light Valve
Various types of variable-area track, including standard and push-pull, may be obtained by various arrangements of the light-valve ribbons. A mathematical analysis is made of the effect of various light-valve constants on the magnitude of the resonance-peak and frequency-response measurements of an improved light valve with high magnetic damping are given. A theoretical study of the effect of azimuth deviation on unilateral, dulateral, and bilateral tracks is included in the paper and is illustrated with graphical charts of the distortion produced by various amounts of azimuth deviation for these types of tracks.
