Abstract
PURPOSE:To suppress the oscillation of a driving current with low power consumption by connecting two load means to two coils in parallel only in the neighborhood of a part where the driving current supplied from each coil driving means to the two coils goes to zero, respectively. CONSTITUTION:First and second coils 18 and 19 to drive a bubble by generating a rotary magnetic field are provided on a bubble memory device 17, and each coil is driven by first and second driving currents 11 and 12 with phases different with each other from first and second coil driving means 15 and 16, respectively. Furthermore, first and second control means 22 and 23 are provided, and first and second load means 20 and 21 are connected in parallel with the first and second coils 18 and 19 only in the neighborhood of the part where supplied first and second driving currents go to 0s, respectively. In such a way, it is possible to suppress the oscillation of the current at the time of stopping the coils 18 and 19 for generating the rotary magnetic field, and also, to reduce the power consumption in a load circuit for controlling the oscillation remarkably.
