Provided is a magnetic recording medium in which a lubricant layer contains a compound A represented by formula (1) and a compound B represented by formula (2), satisfies (A/B) = 0.2 to 3.0, and has an average thickness of 0.8 nm to 2 nm. R1-C6H4OCH2CH(OH)CH2OCH2-R2-CH2OCH2CH(OH)CH2OH ··· (1) (R1 is an alkoxy group having 1 to 4 carbon atoms. R2 is -CF2O(CF2CF2O)x(CF2O)yCF2- (x, y = 0 to 15), -CF2CF2O(CF2CF2CF2O)zCF2CF2- (z = 1 to 15), -CF2CF2CF2O(CF2CF2CF2CF2O)nCF2CF2CF2- (n = 0 to 4). HOCH2CF2CF2O(CF2CF2CF2O)mCF2CF2CH2OCH2CH(OH)CH2OH ··· (2) (m is an integer). |
