Abstract:
The present invention relates to a magnetic recording medium in which a lubricant layer contains a compound A represented by general formula (1) and a compound B represented by general formula (2), satisfying (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).
