摘要：
A magnetic bubble memory device comprises contiguous-disk ion-implanted magnetic bubble propagation tracks formed by implanting selectively ions in a magnetic layer which can hold magnetic bubbles. At least one of the disks which form the ion-implanted bubble tracks and each of which may have a circular or square shape, is configured to include a combination of arcs of circles having different curvatures or a combination of sides of squares having different sizes.
