ABSTRACT:
A hybrid magnetic bubble memory device includes, magnetic bubble propagation tracks formed of partial ion-implantation and bubble propagation tracks formed of a soft magnetic material pattern. At least one of the junctions between the two type tracks is located on a corner soft magnetic material pattern where the bubble propagation direction is changed, and the hairpin conductor is superposed on the part of the corner pattern under which the magnetic material is not ion-implanted to form ion-implanted propagation tracks.
