PERPENDICULAR MAGNETIC RECORDING MEDIUM AND METHOD OF MANUFACTURING SAME

摘要

PERPENDICULAR MAGNETIC RECORDING MEDIUM AND METHOD OF MANUFACTURING SAMEThe present invention provides a perpendicular magnetic recording medium which exhibits reduced noise and improved performance such as SN ratio, and which can realize high magnetic recording densities. In the perpendicular magnetic recording medium, at least a first nonmagnetic intermediate layer, second nonmagnetic intermediate layer, and magnetic recording layer are stacked in order on a nonmagnetic substrate; the first nonmagnetic intermediate layer is formed from a CoerRuW alloy, and the second nonmagnetic intermediate layer is formed from an Ru-baseFig. 1
