A magnetic recording medium comprises a substrate and a magnetic layer provided on the substrate, and has a surface profile satisfying the following conditions (1) to (6): (1) the number of peaks which project above a slice line at a depth of 25 ANGSTROM from the maximum peak height (PC25) is 5 to 100/mm; (2) the ratio of the number of peaks which project above a slice line at a depth of 50 ANGSTROM from the maximum peak height (PC50) to PC25 (PC50/PC25) is 1 to 3; (3) the ratio of a high spot count (HSC) at the center line to PC25 (HSC/PC25) is 1 to 4; (4) the skewness is 1 to 5; (5) the maximum peak height is 60 to 200 ANGSTROM ; and (6) the bearing ratio at a depth of 50 ANGSTROM from the maximum peak height is not more than 3%. |
