PURPOSE:To improve the traveling stability of the titled medium by providing a layer consisting of niobium carbide on a side opposite to the magnetic recording layer. CONSTITUTION:A layer consisting of niobium carbide is provided opposite to a magnetic recording layer. Namely, a magnetic recording medium is formed with the magnetic recording layer 1, a nonmagnetic substrate 2 and a rear lubricating layer 3. The thickness of the magnetic recording layer 1 is regulated to 0.5-10mum in case of a coating type and controlled to 0.05-1.0mum is case of a thin-film type. Polyimide, polyamide, etc., can be used as the material of the nonmagnetic substrate 2. The rear lubricating layer 3 is a thin film consisting of niobium carbide and NbC, Nb2C and their eutectic mixture can be exemplified. Consequently, a recording medium having an excellent traveling stability and which is hardly creased in winding in the producing process is obtained. |
