PURPOSE:To avoid the malfunction of transfer of magnetic bubbles between transfer paths by providing a strip pattern made of a nonmagnetic substance along the transfer direction of the magnetic bubbles between ion implanting transfer paths constituting a minor loop. CONSTITUTION:The strip pattern PS made of a nonmagnetic substance such as Mo or Au is formed along the transfer direction P of magnetic bubbles B among ion implanting transfer paths m1-m3 constituting the minor loop (m) group. Since the strip pattern PS is provided among the paths m1-m3, a potential barrier is formed on a buffle magnetic material LPE due to stress from the strip pattern PS. Then the potential barrier avoids the transfer of the magnetic bubble B to adjacent ion implanting transfer paths.
