METHOD FOR MANUFACTURING MAGNETIC RECORDING MEDIUM AND MAGNETIC RECORDING REPRODUCING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnetic recording medium and a magnetic recording and reproducing device so that both of corrosion resistance and floating property are improved. SOLUTION: After a lubricant 3 is applied on the surface of a surface protective film 2 formed on the surface of a magnetic recording medium 1, the medium is exposed to an ozone atmosphere 4 and the surface free energy of the surface of the magnetic recording medium 1 is controlled to <=15 mN/m.
