摘要： A magnetic recording medium and a magnetic disk device using the same. The magnetic recording medium comprising a nonmagnetic substrate having applied thereon, through two or more chromium-based underlayers, a magnetic recording layer having a circumferential direction of easy magnetization and containing cobalt as a principal component thereof, and also containing chromium and platinum in combination with tantalum or tantalum and niobium. Using the magnetic recording medium, a reproducing output and S/N ratio can be increased without causing an increase in noise.
