发明名称 Magnetic recording medium and method for producing the same
摘要 A magnetic recording medium includes a nonmagnetic substrate and a magnetic layer which is formed on a surface of the substrate and which has an axis of easy magnetization inclined from a direction to normal plane of the layer. An angular dependency of coercive force, of the medium which is measured by changing an application angle of a magnetic field in a range relative to -90 DEG to +90 DEG from the plane of the layer with a plane normal to the layer and including the axis of easy magnetization, has two local maximum values and two local minimum values. A ratio of the local maximum value closer to a plane direction to the minimum value closer of the layer to the local plane direction of the layer is from 1.6 to 2.4, and the local maximum value closer to the plane direction of the layer is larger than the local maximum value closer to the line normal to of the plane of the layer. The medium has a high S/N ratio.
