US 5,852,533 A · Magnetoresistance effect transducer element with continuous central active area

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.

Dependent claims

A magnetoresistance effect transducer element comprising:

a laminated film structure that generates a magnetoresistance effect;
a magnetic domain control film that applies a bias magnetic field to said laminated film structure;
a pair of lead conductor films;
said laminated film structure and said magnetic domain control film are laminated to one another to form a continuous central active area;
said laminated film structure layer and said magnetic domain control film extend fully from one lateral side of the central active area to an opposite lateral side of the central active area;
said pair of lead conductor films are respectively formed on each said lateral side along a lateral side end surface in a direction at a right angle to a direction of lamination of said central active area;
and at least one of said lateral side end surfaces extends obliquely in said direction of lamination of said central active area.
