Magnetic bubble transmission system
 A magnetic bubble transmission system in which a magnetic bubble is retained in a magnetic thin plate under an appropriate bias magnetic field applied to said magnetic thin plate in a direction perpendicular thereto and in which said magnetic bubble is transmitted by reducing and restoring the intensity of the bias magnetic field. A single conductor line is disposed in close contact with the magnetic thin plate. Magnetic patterns magnetostatically coupling with the magnetic bubble are disposed along the conductor to develop at least one desired transmission path of the magnetic bubble line in such a manner that their width are monotoneously reduced at regular intervals in the desired transmission path of the magnetic bubble. The intensity of the bias magnetic field in the area extending along said conductor line is reduced and restored by a pulse current flowed in the conductor line. The transmission step of the magnetic bubble can be controlled by changing the level of the pulse current.
