Abstract : Replication in a magnetic bubble device is realized by a method of operation that is based on the principle of stretching, then cutting the bubble by the control current pulses. In this mode of operation, the bubble is stretched, under the influence of a large amplitude current pulse in the control conductor, between the switch propagate element in the primary track and another propagate element in the secondary track. The bubble strip is let to propagate for a fraction of a field cycle after which a second large amplitude narrow pulse is applied to the control conductor to sever the bubble strip into two parts. One part propagates as would the original bubble n the primary track and the second part propagates in the secondary track. (Author)
