Abstract

After he had listened to his voice on the wonderful wire recorder of the late 1930s, Dr. Vagtborg, director of Armour Research Foundation asked, “Why must the wire move so fast? Why can’t we record slower and longer on the same record?” In other words, why not increase the recording density?
