Soft magnetic films for head core materials mainly electrodeposited CoNiFe based films developed by us were introduced. Electrodeposited CoNiFe thin film has high saturation magnetic flux density (Bs) and low coercivity. Magnetic properties except for Bs and corrosion properties of these films were depended on very small amount of inclusion such as S and H elements. The increase in resistivity (ρ) on the base of this high Bs CoNiFe thin film was developed by controlling very small amount of C inclusion. Finally, application of the film to new type of magnetic recording head was reported.
