Title: Compound detector for magnetic domain memory devices

Abstract: In a magnetic domain memory, a domain detector system includes a passive domain splitter in a domain propagation track, a first detector in the propagation track for detecting one of the domains from the splitter, and a second detector in an auxiliary propagation track which extends from the splitter, the detector outputs being combined to enhance the total output signal. The relative angular orientation of the detectors may be varied to provide any desired signal shaping. The passive splitter has features which ensure reliable domain splitting characteristics.
