Abstract: THE OUTPUTS ACHIEVED IN NONDESTRUCTIVE READ OPERATIONS OF MAGNETIC CORE MEMORIES OPERATED IN A DIFFERENTIAL PERMEABILITY MODE ARE ENHANCED BY A PULSE ADDED TO THE SELECTION PULSE TRAIN TO DRIVE TO RELATIVELY HIGH PERMEABILITY STATES ONLY THOSE CORES IN A SELECTED WORD WHICH ARE IN A PARTIALLY SWITCHED CONDITION. THE INCREASED PERMEABILITY PERMITS ENHANCED OUTPUTS IN PARTICULAR MODES OF OPERATION.

Abstract: A single wall domain propagation arrangement herein includes magnetically soft overlay patterns which generate magnetic poles in response to reorienting inplane fields to move domains in propagation channels defined thereby. The arrangement is organized for high packing density and fast access by providing parallel recirculating bit channels to move consecutive binary word representations to a common recirculating channel. The common channel moves the word to a common read-write area. Information moves synchronously in the common channel, as well as in the parallel channels, permitting the return of information to the parallel channels with little logic circuitry.

Abstract: Single wall domain propagation circuits include herein both magnetically soft overlays which define propagation paths along which domains move in response to reorienting in-plane fields and electrical conductors which act on magnetically hard regions in the overlay, when pulsed, to modify locally pole patterns generated by the in-plane fields. An organization in which domains are moved in a manner to eliminate unwanted effects of current pulses in those conductors on stored domain patterns is described.

Abstract: An improved source of single wall domains is described where a magnetically soft overlay pattern is structured to stretch a domain in response to a reorienting field in the plane of the material in which single wall domains are moved.

Abstract: Single wall domains are moved in a slice of magnetic material by magnetically soft overlay patterns on both surfaces of the slice. The overlays are shaped alike and are offset one from the other along the axis of domain movement so that each provides pole patterns to attract a domain to the same consecutive positions as a magnetic field reorients in the plane of the slice.
