YOKE TYPE MAGNETIC REPRODUCING HEAD, ITS MANUFACTURING METHOD AND MAGNETIC DISK DEVICE

摘要

PROBLEM TO BE SOLVED: To make it possible to prevent the fall of the yield and generation of the Barkhausen noise as much as possible. SOLUTION: This method is characterize in comprising a step of including a magnetic sensitive layer with a magnetization in plane, forming a current perpendicular to plane type magneto resistive effect film 4 which perpendicularly runs the sense current to a film plane and carrying out patterning into a component configuration, and a step of forming a magnetic yoke 12 which covers the magneto resistive effect film 4 carried out patterning into the component configuration.
