A double layer perpendicular magnetic recording medium having a high medium
S/N ratio at a recording density of 50 Gb/in.sup.2 or higher and a
magnetic storage apparatus with a lower error rate and excellent
reliability are obtained with a structure having soft magnetic underlayer
12, an intermediate layer 13 and a perpendicular magnetic recording layer
14 are sequentially formed on a substrate 11. The, intermediate layer 13
is made to be a non-magnetic amorphous alloy, in which Ni is a main
component and Zr is contained, and the soft magnetic underlayer 12 is
constituted of ferromagnetic nano-crystals precipitated by annealing.
