Abstract:
1. A method for manufacturing a magnetic head, the method comprising: forming a stacked film on a first magnetic shield including at least one of Fe and Co, the stacked film being configured to form a stacked body, the stacked body including a first magnetic layer, a second magnetic layer, and an intermediate layer provided between the first magnetic layer and the second magnetic layer; forming the stacked body by removing a part of the stacked film by etching; forming a side wall film by over-etching the first magnetic shield to cause a material included in the first magnetic shield to adhere to a side wall of the stacked body, the side wall film including at least one of Fe and Co and having a composition different from a composition of the first magnetic layer and different from a composition of the second magnetic layer; and forming a second magnetic shield on the stacked body to form a reproducing unit.
