Yoke type magnetic transducer head utilizing a magnetoresistance effect.

摘要

A yoke tyope magnetic transducer head utilizing a magnetoresistance effect in which a magnetoresistance effect sensing portion (5) is provided so as to magnetically couple a cut-away portion in a magnetic circuit including an operation gap (g) and a magnetic yoke (8) having in its one portion the cut-away portion and in which a first bias magnetic field is applied to the magnetoresistance effect sensing portion (5) by a first magnetic flux that is generated when a current is flowed through the magnetoresistance effect sensing portion (5), or when a current is flowed through both the magnetoresistance effect sensing portion (5) and a bias conductor (3), which includes a hard magnetic layer (14) for generating a second magnetic flux by which a second bias magnetic field is applied to the magnetoresistance effect sensing portion (5) and for passing through the magnetic yoke (8) a magnetic flux which cancels at least a part of the first magnetic flux which passes through the magnetic yoke (8).
