Since a magnetic bubble memory is nonvolatile, a power failure does not affect the data stored in the memory. It does, however, destroy the count in the bubble position counters associated with the memory. Thus, when power is restored, you do not know where the various blocks of data are inside the memory. The present technique provides an efficient, reliable and economical way of resynchronizing the bubble memory counters after correction of a power failure.
