Abstract
An active replicate/transfer magnetic bubble domain switch which is especially compatible with gap tolerant structures is provided. The switch includes a broadfaced corner element of relatively massive structure which retains the bubble domain for more than one field cycle. The switch characteristics are superior to those of existing switches both at the 8 .mu.m and 16 .mu.m periods. The switch offers the advantages of good bias and phase margins, ease of fabrication and reduced drive field requirements. In the 8 .mu.m, version the device requires a substantially lower drive field than the pickax design by virtue of reduced bubble-bubble interaction in the minor loops.
