ABSTRACT:
The two drive coils commonly used for moving magnetic bubbles in a bubble memory are driven by a pair of reactive-coupled tuned circuits. The tuned circuits are designed to maintain the proper phase relationship between currents in the circuits and to provide periodic refresh pulses once operation is initiated.
