Abstract
There is described a bubble domain field access device component for providing continuous generation of a stream of bubble domains. The device is in the nature of a passive generator which is preferably constructed using one-level processing. The device uses multiple chevrons (chevron columns) which have the advantages of inherent redundancy, reduced gap tolerances and wide propagation margin. The structure comprises, generally, a rectangular seed plate arranged as a 90.degree., multiple-chevron, corner portion.
