ABSTRACT:
A magnetic bubble memory device for implementing its high storage density for practical use is generally composed of ion-implanted elements occupying the most part of a minor loop, and other elements made of soft magnetic materials. The ion-implanted minor loop with a higher density is folded several times, and includes straight propagation tracks adjacent to each other and connected by an inside turn, with another straight propagation track having an outside turn facing the inside turn being placed between the adjacent straight tracks.
