PROBLEM TO BE SOLVED: To provide a high quality perpendicular magnetic recording medium, having the fewer number of bright spots and nearly free from occurrence of peripheral damage, and to provide a magnetic recording device using the same. SOLUTION: The perpendicular magnetic recording medium 1 formed by providing at least a soft magnetic backing layer 3 and a magnetic recording layer composed of a Co alloy containing an oxide sequentially on a non-magnetic substrate 2 is characterized in that the non-magnetic substrate has≤50Ωcm resistivity. The magnetic recording device using the perpendicular magnetic recording medium is also provided. COPYRIGHT: (C)2006,JPO&NCIPI
