Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an intra-surface magnetic recording medium satisfactorily stable to low noise, high coercive force or thermal fluctuation and to provide a magnetic storage device having high surface recording density and high in reliability. SOLUTION: In the intra-surface magnetic recording medium having a non- magnetic substrate, a base layer formed on the non-magnetic substrate and a magnetic layer formed on the base layer, the medium has a first base layer having an amorophous or fine crystal structure, a second base layer having a body centered cubic structure and a third base layer having a hexagonal dense structure in this order on the non-magnetic substrate and the magnetic layer having a hexagonal dense structure is formed via the third base layer and the third base layer consists of an alloy containing Co and Ru.
