A variety of single tracks as well as a Class A push-pull track can be laid down by a two-ribbon-type valve while both Class A and Class B push-pull readily can be recorded by a three-ribbon structure. Both double-bilateral and doubleunilateral (dulateral) can be obtained from the single tracks by image doubling. An analysis of the effect of azimuth deviation on distortion indicates the dulateral track to be superior to the unilateral for all azimuthal deviations and superior to the bilateral for large values of the deviation.
