PURPOSE:To obtain a composite magnetic bubble having a connecting section stably operated, by increasing a gap between a magnetic bubble transfer path formed with a soft magnetic substance and a magnetic layer holding a magnetic bubble more than the gap at other parts. CONSTITUTION:The gap L between the soft magnetic substance 1 and a magnetic substance 4 holding the magnetic bubble is increased for a desired part only as shown in Figure. The attracting force, i.e., driving force between the transfer path and the magnetic bubble is weaker as the gap L is increased. Thus, only the driving force of a desired soft magnetic transfer path is weakened by increasing partially the gap L. To change the gap between the soft magnetic substance and the magnetic substance holding the magnetic bubble, the thickness of an insulating layer 3 is changed. As the method changing the thickness of the desired part, the photolithography technology being the known technology is used. |
