摘要：
Disclosed is a magnetic bubble memory device having a first bubble propagation path formed in an ion-implanted pattern and a second bubble propagation path formed of permalloy elements, both paths being spaced out from each other by a distance larger than or equal to the diameter of the magnetic bubble, and a propagation path connecting structure in which a hairpin-shaped conductor for connecting both propagation paths is disposed between them.
