MAGNETIC RECORDING MEDIUM AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide means for improving electromagnetic conversion characteristics and running stability.SOLUTION: A magnetic recording medium comprises a nonmagnetic layer containing a nonmagnetic powder and a binder, and a magnetic layer containing a ferromagnetic powder and a binder in this order on a nonmagnetic support. The nonmagnetic layer has a thickness of equal to or less than 300 nm; a composite elastic modulus as measured on a surface of the magnetic layer ranges from 6.0 to 8.0 GPa; the magnetic layer comprises an abrasive with a specific surface area by BET method ranging from 14 m2/g to 40 m/g; and a surface abrasive occupancy on a surface of the magnetic layer ranges from 0.2% to 2%.
