ABSTRACT:
A method of manufacturing a magneto-resistance effect type head that includes an element portion of magneto-resistance effect type and reproduces a read signal of data from a recording medium by the element portion, is proposed. The method includes applying a predetermined DC current to the element portion; and performing heat treatment on a part of the element portion that has been thermally deformed due to application of the DC current.
