ABSTRACT:
There is described a magnetic bubble domain device particularly adapted for bubble domain detection. A bubble is supplied via a standard input propagation path, expanded to an elongated bubble comfiguration and replicated into a plurality of bubbles. The plurality of bubbles propagate along a respective plurality of propagation paths and reach a detector portion, preferrably at different times. The detector portion is arranged to receive bubbles along the respective plurality of paths and to produce enlarged bubbles representative of each of the bubbles replicated from the original bubble. Consequently, the original bubble has been enlarged by elongation and by replication wherein detection of the original bubble is enhanced.
