摘要： To suppress a magnetic wall movement in the structure including an amorphous magnetic layer as a recording layer, and to realize a high density recording with a sufficient signal quality level, a magnetic recording medium includes an amorphous magnetic layer (recording layer) formed on a substrate, a non-magnetic metal element layer (underlayer) formed between the substrate and the amorphous magnetic layer, wherein an average surface roughness Ra of the non-magnetic metal element layer is in a range of 0.7 nm to 2.0 nm. The foregoing structure having the non-magnetic metal element layer of a large average surface roughness Ra brings about a great pinning effect onto the amorphous magnetic layer, thereby forming magnetic bits under stable conditions when carrying out a high density recording.
