Abstract:
Embodiments in accordance with the present invention provide a magnetic head having a narrow track width and excellent in productivity for the purpose of realizing a disk storage unit having a large capacity. In a magnetic head having a plurality of flairs on a main magnetic pole, a side shield is formed via a non-magnetic film on both sides of the flair disposed close to an air bearing surface in such a fashion as to be aligned with the flair.
