Title: Sinusoidal film plated memory wire

Abstract: Synchronous plating techniques for reducing adjacent bit disturb charactetics or interactions in a magnetic memory wire include the step of sinusoidally and smoothly depositing the magnetic layer on the outside surface of the wire so as to increase the effective magnetic path length between adjacent bits. The resultant wire has changing cross-sectional dimensions corresponding to the varying sinusoidal configuration of the wire. This invention concerns a film-plated memory wire of improved characteristics and the method of making the same. The term "memory wire" is used to designate a magnetic recording and reproducing element for recording or reproducing magnetic signals by magnetic flat interlinkage with a magnetic transducer head during relative motion of the wire and head.
