In magnetic bubble domain storage systems, it is important that the data exit from the storage in the same sequence in which it entered the storage. In major/minor loop memory organizations using separate read and write major paths, this is easily achieved with gapped progagation elements such as T-bars, C-bars, half disks, and chevrons. However, because contiguous disk propagation elements are gapless, this has not been achieved. To solve this, a data reversal switch is provided which reverses the order of the data before it is entered into the minor loop storage registers. When the data is removed from the minor loops, it will have the same sequence as it had initially, thus avoiding data reversal. The data reversal switch is comprised of two adjacent, oppositely propagating contiguous propaation element patterns in which a parallel transfer of sequentially written data can be made. This reverses the order of the data from what it was initially, so that upon exiting from the storage loops the initial order will again be achieved.
