    Abstract: A thin film magnetoresistive sensor of NiFeCo is juxtaposed with a saturable thin film shield of more highly permeable NiFe material. The curve depicting change of resistance of the sensor as a function of applied magnetic field is flattened, permitting the sensor to provide a magnetic switch, such as a keyboard transducer, a sensor of current through wires, a magnetic bubble detector and a remote control scanning sensor in a recording head. The scanner involves a stepped arrangement for providing different levels of sensitivity for adjacent sections of the magnetoresistive sensor.
