Abstract
A bubble domain replicator for ion-implanted contiguous disk devices has a cusp portion and a tip portion extending substantially away from the cusp portion so that the cusp forms part of a super track and the tip forms part of a bad track. A hairpin conductor is positioned over the cusp portion and tip portion so that the closed end of the hairpin is closest to and surrounds the end of the tip portion.
