Abstract
A magnetoresistance effect magnetic head includes a magnetoresistance effect element having first and second ends. An electrically insulating biasing portion is at ends of the magnetoresistance effect element to apply a longitudinal bias magnetic field to the magnetoresistance effect element and to suppress leakage current at the ends of the magnetoresistance element. The biasing portion can include an intermediate longitudinal bias application layer disposed between a first insulating antiferromagnetic layer and a second layer that can be an antiferromagnetic layer. The bias portion can also be formed as one bias application layer.
