Abstract
Consecutive bit bubble memory devices employ a dummy detector element separated from the detector element. This arrangement causes substantial background magnetoresistor noise. The dummy detector of the present invention is located in a novel dummy array which minimizes the magnetoresistor noise, enhances the signal-to-noise ratio and enables the detection of bubble domains without error.
