ABSTRACT:
There is provided a magnetic recording medium which exhibits superior lubricating properties and superior tape-transport properties as well as superior robustness even in a low-temperature environment. A magnetic layer containing a ferromagnetic metal is formed on a nonmagnetic support, and a protecting film is formed on the magnetic layer. A lubricant auxiliary coating composition comprising an aromatic alcohol is applied to the protecting film to form a lubricant auxiliary layer, and a lubricant coating composition comprising a compound represented by the formula (1) below is applied to the lubricant auxiliary layer to form a lubricant layer.in-line-formulae description="In-line Formulae" end="lead"?R1CH(COOR2)CH2COOR3 (1)in-line-formulae description="In-line Formulae" end="tail"?wherein R1represents an aliphatic alkyl group, an aliphatic alkenyl group, or a hydrogen atom, and each of R2and R3independently represents a fluoroalkyl group, a fluoroalkenyl group, a fluoropolyether group, or a hydrogen atom.
