Abstract
An improved magnetic bubble replicator is characterized by relatively high bias and phase margins. Both the orientation of a replicate conductor with respect to a permalloy replicator element and the shape of the replicator element are shown to be important in determining those margins. Such replicators are typically employed to produce an image of a bubble pattern in a channel adjacent a plurality of closed loop paths in which the bubble pattern moves.
