Substrate For Perpendicular Magnetic Recording Medium, Method Of Manufacturing The Same, And Perpendicular Magnetic Recording Medium
摘要:
A substrate for perpendicular magnetic recording medium 2 is provided with a soft magnetic substrate coat 5. On this soft magnetic substrate coat 5, an anticorrosion coat 5 is formed. The anticorrosion coat 6 is preferably formed so as to completely cover the entire soft magnetic substrate coat 5.
