Abstract
A method of manufacturing a magnetic recording medium with high recording density and enabling stable flight of a magnetic head, with high manufacturing yields, is provided. The method includes layering a magnetic layer, a protective layer, and a lubricating layer in order on a substrate, and forming a medium for transfer. The method further includes transferring a magnetic pattern to the medium for transfer, and flattening a surface of the lubricating layer of the medium for transfer for which the magnetic pattern transferring is completed. The surface of the lubricating layer is flattened either by wiping the surface of the lubricating layer using a member without a cutting effect, or by heating the surface of the lubricating layer.
