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 <=2.5mum and inert materials. CONSTITUTION:The magnetic layer is provided on the nonmagnetic base material containing a titanium compound whose average particle size is <=2.5mum and inert materials. It is desirable that the titanium compound and inorganic matters have <=2.5mum average particle size and it is more desirable that they have 0.05- 0.5mum average particle size; and when 0.03-10wt% titanium compound and inorganic matters are incorporated in 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. The proportion of said titanium compound to inorganic matters is optional if the titanium compound is >=0.02wt%.
