ABSTRACT:
A magnetic bubble detector for an ion-implanted bubble memory is achieved by using a permalloy detector element and two conductors. The conductors are operative first to stretch a bubble from one position in a bubble path and then to destretch it, after detection, from the detector element to another position in the path. The detector has been operated at 100 kilohertz.
