ABSTRACT:
A magnetic transducer and method of operation is disclosed for removing the effect of interference magnetic fields present when detecting information magnetically coded on a carrier. The transducer is provided with a magnetoresistive compensating element disposed to develop a voltage in response to the interference magnetic fields equal to that developed across a magnetoresistive detecting element; however, the compensating element is positioned out of the magnetic leakage field of the coded information.
