抄録

A soft magnetic undercoating layer for perpendicular recording media was prepared by electroless plating method, and the most optimum plating conditions were investigated.<br>The iron content of nickel-iron-phosphorus films varied from 0 to 18% with the ferrous sulfate concentration in the plating solution. The addition of iron to nickel-phosphorus plating film decreased their coercive force and increased squareness. Film deposited from the most optimum plating solution exhibited coercive force of 1.0 Oe and squareness of 0.95 and showed strong (111) plane orientation, which improved the anisotropy of perpendicularly magnetized film.
