Abstract
Progression from standard variable-area types of recording to class A push-pull and finally from class A to class B push-pull was primarily motivated by an appreciation of the inherent advantages of the push-pull types of recordings, and an ability to perfect processing and recording controls necessary to realize the finer qualities of the class B push-pull recording. The adoption of class B push-pull variable-area for original recording has eliminated distortion introduced by noise-reduction systems, and has reduced background noise by at least 6 db.
