PURPOSE:To obtain a magnetic recording medium having good runnability and excellent durability by forming an underlying layer contg. a ferrite compd. on the surface of a magnetic layer provided on a nonmagnetic substrate and further laminating a polymerized film of p-xylylene or the deriv. thereof as a lubricating layer atop said layer. CONSTITUTION:The underlying layer 3 contg. the ferrite compd. is formed on the surface of the magnetic layer provided on the nonmagnetic substrate 1. The magnetic recording medium is constituted by further laminating the polymerized film of the p-xylylene or the deriv. thereof as the lubricating layer 4 thereon. The ferrite compd.-contg. layer to be used for the underlying layer 3 is the oxide of Fe or the composite oxide formed by mixing Mn, Zn, Cu, Co, Ni and Cr respectively alone or in combination at adequate ratios therewith. The wear resistance and adhesive power of the underlying layer itself act to sustain the low friction characteristic of the lubricating layer by interposing such underlying layer. The magnetic recording medium having the good runnability and the excellent durability is thereby obtd. |
