Abstract
The present invention is directed to a magnetic transducer element with outstanding productivity, with which the track width can be defined to a high degree of accuracy and required magnetic characteristics can be reliably imposed upon the central active area. Laminated films which generate a magnetoresistance effect, a magnetic domain control film, which applies a magnetic bias to the laminated films and a pair of lead conductor films are provided. The laminated films and the magnetic domain control film are laminated to each other to constitute a central active area. The lead conductor films terminate the side end surfaces of the central active area at the two sides in direction running at a right angle to direction of the lamination of the central active area.
