Magnetic bubble device |
摘要 |
A magnetic bubble device has minor loops formed through ion implantation and used for storing information. As the density becomes higher, inside turn corner portions are formed on the minor loops. Dummy patterns having circular, triangular or other shapes are disposed in the vicinity of the corner portion. It is desirable that the minimum distance X between the dummy pattern and the propagation track satisfy the relation of 1.5 D</=X</=3.5 D, where D represents the diameter of a bubble.
