Abstract :
In this study, an investigation was made to discover methods of storing more bits on a Williams tube than can be stored by conventional methods. Read-around was ignored because the object was to explore the Williams tube as a secondary memory for non-random access operations. Proceeding on this basis, it was found that a four-fold increase in packing is possible with established techniques, and an even greater increase with other methods described in this paper. Such a memory is more versatile than a magnetic drum, as shown by the example of machine organization presented in this paper.
