PROBLEM TO BE SOLVED: To provide a recording medium excellent in continuous sliding, durability, low in tackiness and high in meniscus force by incorporating liquid crystal molecules having a specified monocyclic structure as a lubricant into the outermost layer. SOLUTION: The outermost layer of a magnetic recording medium having magnetic layers on a nonmagnetic supporting body contains a lubricant containing liquid crystal molecules having a monocyclic structure expressed by a general formula of L-X<1> -R or L-X<2> . In the formulae, X<1> , X<2> are atomic groups having cyclic structures, L, R are cyano groups, nitro groups, aldehyde groups, hydroxyl groups, amino groups, amide groups, ether groups, carbonyl groups, carboxyl groups, oxycarboxyl group, halogen groups, alkyl groups, allyl groups, hydroxyimino groups, or allyl groups, alkyl groups, oxycarboxyl groups, carboxyl groups, carbonyl groups, ether groups, amide groups and amino groups with substitution of groups above described. The lubricant is applied on the surface of a magnetic material or added in the magnetic layer. |
