PROBLEM TO BE SOLVED: To more improve recording density in a magnetic recording medium and a memory device. SOLUTION: The magnetic recording medium comprises a non-magnetic granular layer and a recording layer arranged on the non-magnetic granular layer, wherein the recording layer comprises a first granular magnetic layer arranged on the non-magnetic granular layer and a second granular magnetic layer arranged on the first granular magnetic layer, and wherein a non-magnetic material to be used for the magnetic separation of metal particles contained in the non-magnetic granular layer is different from a non-magnetic material to be used for the magnetic separation of magnetic particles contained in the first granular magnetic layer.
