Techniques for increasing storage density of magnetic drum systems

Published:08 December 1954Publication History

ABSTRACT

The problem of increasing the number of digits per linear inch of track length which can be reliably stored on and recovered from a magnetic medium is considered herein. The techniques to be described evolve from two well-known recording systems: the return-to-zero (RZ) and non-return-to-zero (NRZ) systems. The modifications concern both the nature of the recording and the method of reading back the information. The techniques can be used for tape storage as well as for drum storage.
