ABSTRACT:
SLM field access bubble devices which include at least one conductor crossing a bubble propagation path have severely limited operating margins (especially for small bubbles) for the bubble in the vicinity of the conductor. Apparatus and method for operating such a bubble device is disclosed which improves the device operation in this region. The improved apparatus and method provides an additional field source with a sense and magnitude to support the bubble when it reaches the conductor region. Such a field source, as disclosed, includes a current pulse in the conductor.
