ABSTRACT:
A magnetic bubble storage device is formed with a major-minor loop organization wherein the bit pitch in at least a part of a first region of the major loop other than a second region where the major loop and the minor loops are connected is larger than the bit pitch in the second region. This permits the realization of a pattern arrangement with a broader operating margin and also facilitates the addition of redundant minor loops.
