    Abstract: This disclosure relates to a transducer apparatus for the nondestructive readout of tapes and other magnetic records which apparatus includes a magnetizable thin film mounted on a planar substrate and which is anisotropic in nature having a preferred or easy direction of magnetization. The film is provided with a conductor parallel to the easy axis of magnetization and also conductor normal to the easy axis of magnetization with the conductors oriented relative to the film such that current pulses sent through the first conductor will not induce an appreciable signal in the other conductor without the presence of an external magnetic field while such current pulses sent through the first conductor will induce either a positive or negative sense signal in the presence of an external magnetic field.
