Abstract
A magnetic bubble detector which includes chevron propagation elements and underlying thin film magnetoresistive members is described. A portion of the dummy detection member is misaligned from its overlying chevrons. This misalignment provides a bias to the detection circuitry. A negative voltage is detectable when no bubble is present and a positive potential when a bubble is present. This allows easy matching between the detector and sense amplifier.
