Abstract
An in-plane magnetic holding field, long known to provide improved operating margins for a magnetic bubble memory during stop-start operation, is produced by unique bias magnet designs each of which provides a constant in-plane bias field in a manner consistent with normal bubble propagation as well as with stop-start operation.
