Abstract
This paper gives a general analytical theory of reproducing variable width records with oblique images. Two types of records are considered. In each case the effect of obliquity is to introduce non-linear distortion and loss of power; but the amount of distortion produced and its dependence on the modulation are different in the two types of records. The loss due to the width of the image is practically independent of the orientation of the reproducing image. Curves are given which show the amount of distortion produced by an error of orientation of 43 minutes when the width of the sound-track is 0.080 inch.
