Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a recording medium capable of imparting magnetic characteristics optimum for high density in-plane magnetic recording to the magnetic layer, and to obtain a magnetic storage device having large capacity by using the medium. SOLUTION: An underlying layer 12 consisting of a nonmagnetic Ni-based alloy having a fcc structure is formed between a nonmagnetic substrate 11 and a Co-based alloy magnetic layer 13. In the layer 12, the (100) plane of the fcc structure is aligned along the normal line direction of the plate, and the Co-based alloy magnetic film 13 having a hcp structure is formed by epotaxially growing the (110) plane on the underlying layer.
