PROBLEM TO BE SOLVED: To provide a magnetic recording medium which can maintain a sufficient sliding durability characteristic and corrosion resistance, at a high surface recording density of equal to or more than 600 gigabits/square inch. SOLUTION: The disk-like magnetic recording medium of a magnetic recording system recorded at the surface recording density of equal to or more than 600 gigabits/square inch is provided with a lubrication layer on the surface of the disk-like magnetic recording medium comprising a surplus layer and a fixed layer, wherein the ratio of the surplus layer to the fixed layer is different according to the surface region of the disk-like magnetic recording medium. The long-term sliding durability can be maintained, and the recording/ reproducing can be achieved in the condition of the high surface recording density of equal to or more than 600 gigabits/square inch.
