MAGNETIC RECORDING MEDIUM, METHOD OF MANUFACTURING THE SAME AND MAGNETIC MEMORY DEVICE

PROBLEM TO BE SOLVED: To provide a magnetic recording medium which can record and reproduce high-density information and has high coercive force, low noise, high S* and high reliability. SOLUTION: The magnetic recording medium is arranged with information recording layers 15 and 15' consisting of magnetic films of a Co-base alloy system through at least two nonmagnetic ground surface films on a substrate 11, in which first nonmagnetic ground surface films 13 and 13' arranged on the most substrate side of the nonmagnetic ground surface films consist of composite films essentially consisting of Cr and containing at least one element of the group consisting of Zr, Si, Al, Ti, V, Ta, and Y and oxygen and the concentration of the elements is specified to 1 to 20 atom.% and the concentration of the oxygen to 1 to 30 atom.%.
