Magnetic recording medium and magnetic recording and reproducing apparatus

A magnetic recording medium comprising at least a magnetic layer, a protective layer, and a lubricant layer on a nonmagnetic substrate in this order,

• wherein an outermost surface of the protective layer on the lubricant layer side contains carbon and nitrogen,
• the nitrogen is contained in the outermost surface in a range of 50 atomic % to 90 atomic %,
• the lubricant layer is formed by being in contact with the outermost surface, has an average film thickness of 0.5 nm to 2 nm, and contains a compound A represented in the below general formula (1), a compound B represented in the below general formula (2), and a compound C represented in the below general formula (3), and
• a mass ratio (A/(A+B+C)) of the compound A with respect to a s of masses of the compounds A, B, and C contain d in the lubricant layer is in a range of 0.05 to 0.6, a mass ratio (B/(A+B+C)) of the compound B with respect to the sum of the masses of the compounds A, B, and C contained in the lubricant layer is in a range of 0.05 to 0.5, and a mass ratio (C/(A+B+C)) of the compound C with respect to the sum of the masses of the compounds A, B, and C contained in the lubricant layer is in a range of 0.05 to 0.9,
• R1-C6H4OCH2CH(OH)CH2OCH2—R2-CH2OCH2CH(OH)CH2OH (1)
• in the general formula (1), R1 is an alkoxy group having 1 to 4 carbon atoms, R2 is —CF2O(CF2CF2O)x(CF2O)yCF2— (an order in parentheses of x and y may be this order, the opposite order, or a random order (each of x and y is an integer of 0 to 15).)
• CH2(OH)CH(OH)CH2OCH2CF2CF2(OCF2CF2CF2)mOCF2CF2CH2OCH2CH(OH)CH2OH (2)
• in the general formula (2), m is an integer in a range of 4 to 50,
• HOCH2CF2CF2O(CF2CF2CF2O)sCF2CF2CH2OCH2CH(OH)CH2OH (3)
• in the general formula (3), s is an integer.
