An optical magnetic recording medium in which reproduction is implemented by transcribing a mark to a reproducing layer (13) based on a magnetic field from a recording layer, includes a reproducing layer (13), a non-magnetic layer (15), and a recording layer including a first recording layer (16) and a second recording layer (17), wherein the reproducing layer (13), the non-magnetic layer (15), and the recording layer including the first recording layer (16) and the second recording layer (17) are stacked in this sequence; the reproducing layer (13) has a property of an easy magnetization in an in-plane direction at room temperature; the first recording layer (16) and the second recording layer (17) each has a property of easy magnetization in a vertical direction to the in-plane direction at room temperature in a single layer; and there is a relation of M2
