Abstract

1315694 Magnetic domain shift register FILMFABRIK WOLFEN VEB 17 July 1970 34776/70 Heading G4C [Also in Division H3] In a shift register, bits are propagated along soft magnetic strips 3, Fig. 1, in which local variations of the critical switching field are produced by a pattern of permanently magnetized areas in a hard magnetic layer 2. The magnetic materials are insulated from one another by an elastic layer 4, and the structure is supported by an elastic substrate 1. A pulsed current is used to shift the bits, and may be passed through the strips 3 or the layers 2. The strips 3 may be overlaid with an electrically conductive layer, Fig. 2 (not shown). The permanent magnetic layer may be one or more thin metal layers and/or permanent magnetic particles embedded in a non-magnetic carrier. The shift register may be in the form of a continuously revolving endless tape.
