Harmonic Distortion in Variable-Density Records
Wave-form distortion in variable-density records caused by improper track processing and the ribbon velocity effect of the light-valve is considered from both theoretical and experimental standpoints. General agreement between calculated and experimental values of second-harmonic distortion is attained. Observed values of third-harmonic distortion are considerably greater than those predicted by the theory. Data obtained indicate that rather high values of distortion may result due to non-linearity of the relation between negative track exposure and print transmission.
