ABSTRACT:
Operating margins for major-minor magnetic bubble memories are improved by use of protective rails between minor loops to prevent loss of information due to stripout. The rails, as are the propagation paths, are defined by unimplanted regions in an otherwise ion-implanted layer. In another embodiment, unimplanted rectangular islands are used rather than rails.
