A Digital Static Magnetic Wire Storage with Nondestructive Read-Out

Abstract

After a brief review of pertinent magnetic effects and sonic wave propagation in elastic media, a nonvolatile, digital, magnetic storage scheme is described, wherein binary words may be stored by magnetizing segments of a wire, and the information may be read out an unlimited number of times with no deterioration of the stored information. Two storage schemes are presented: a temporary, electrically addressed storage, and a permanent, program-type store. Bit-storage density, read-out and input pulse shapes, and read-out frequency are noted. Possible limitations such as losses, temperature effects, and pulse shape are balanced against advantages and a comparison is made to a number of other types of bit storage.
