Abstract: Domain propagation along a path defined by a straight line conductor is achieved by driving domains back and forth across the conductor against the edges of regions forbidden to the domains. By angling the edges of the regions with respect to the axis of the conductor and by offsetting those edges associated with one edge of the conductor with respect to those associated with the other, the back and forth motion is translated into movement along the axis.

Abstract: A circuit for controllably inverting the sequence of a serial pattern of single-wall magnetic domains is implemented by offsetting or ''''phasing'''' opposing serrations on the sides of a serrated groove which is superimposed by a serpentine conductor pattern that defines a serial string of enhanced propagationpulse write circuits on both sides of the groove. A propagating pattern of domains on one side of the groove is displaced to the opposite side of the groove in response to an enhanced propagation pulse, thereby reversing the direction and inverting the sequence of domain propagation.

Abstract: Selected write circuits in a serial string of enhanced propagation pulse write circuits are activated by modulating the magnetic bias fields in the local vicinity of the selected circuits a sufficient amount to cause only the selected circuits to respond to enhanced propagation pulses, which are normally of insufficient amplitude to activate any of the write circuits.

Abstract: A ''''write'''' feature is incorporated into the propagation circuitry of a lateral displacement shift register by reducing the lateral dimensions of the serpentine propagation conductor pattern at predetermined ''''write'''' positions along the propagation channel. Enhancement of amplitude of a selected propagation pulse creates a lateral force sufficient to displace a domain at such a position to a side of the channel determined by the polarity of the enhanced pulse.
