Abstract
A field-access, magnetic bubble memory organized in a major-minor configuration includes an extra set of minor loops dedicated to fault correction. The loops of the extra set are coupled to a major path in a manner to move the information in the loops of the set controllably out of synchronism with respect to the information in the remaining loops. Thus, information in the loops of the extra set can be inserted into the data stream originating from the remaining loops at positions of missing data from faulty ones of those loops.
