ABSTRACT
The magnetic cores developed prior to 1952 were nonuniform and, therefore, extremely marginal in their operating characteristics. Not only did they present many circuit problems but they were difficult to manufacture as well. Since 1952, however, the picture has changed radically; rapid development of core materials, more advanced processing techniques, as well as new circuits and design techniques have all combined to place the magnetic core in a position equal to, if not superior to, all other digital components. Today this increased tempo in development is becoming evident in many laboratories and the number of new systems and components that employ magnetic cores is increasing rapidly. In fact, it is quite safe to predict that most computers designed in 1955 will use more magnetic cores than any other 2-state component. The promise of unusual reliability and long life of the magnetic core has been the motivating factor in most of the developments. Then, too, the possibility of reduction in cost, weight, and power requirements has its measure of attraction.
