PURPOSE: To produce a magnetic recording medium superior in electromagnetic transducing characteristic, running capacity, durability (wear resistance), and productivity by providing a magnetic layer on a nonmagnetic base material containing a titanium compound whose average particle size is ≥2.5μm.
CONSTITUTION: The magnetic layer is provided on the nonmagnetic base material containing a titanium compound whose average particle size is ≤2.5μm. It is desirable that the average particle size of the titanium compound is ≤2.5μm, and it is more desirable that it is 0.05W0.5μm; and when 0.03W10wt% titanium compound is incorporated into a base film, the magnetic recording medium superior in electromagnetic transducing characteristic, running capacity, durability (wear resistance), and productivity is produced easily without raising the cost.
