In this paper, it is presented that the experimental results of the magnetic bubble propagation in dual conductor current access test circuits, where the bubble-driving fields can be generated by applying the bipolar pulse currents to the apertured conducting sheets. Under the driving conditions that the current density for the first conducting sheet (I1) was at 0.5 mA/µm, for the second conducting sheet (I2) was at 1 mA/µm, and the frequency of these currents was at 200 kHz, the bias margin for the propagation normal to the currents flow was obtained as much as 5 Oe.
