Abstract: Single wall domains are moved in a sheet of magnetic material along paths defined by pole patterns in magnetically soft overlays in response to reorienting magnetic fields in the plane of the sheet. The direction in which domains move is determined by the magnetic state of high coercive force material adjacent selected portions of the overlay for selectively modifying pole patterns.

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.
