MANUFACTURING METHOD OF MAGNETIC RECORDING MEDIUM, MAGNETIC RECORDING MEDIUM, AND MAGNETIC RECORDING AND REPRODUCING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a magnetic recording medium for achieving higher recording density with higher reliability.SOLUTION: The manufacturing method of a magnetic recording medium at least includes: a step of forming an orientation control layer, on a nonmagnetic substrate, for controlling the orientation of an immediately above layer; and a step of forming a perpendicular magnetic layer in which an axis of easy magnetization is oriented mainly perpendicular to the nonmagnetic substrate. The step of forming the orientation control layer has a step of forming a granular structure layer containing Ru or a material comprising Ru as a main component, and an oxide with a melting temperature of 1000°C or lower by a sputtering method. In the step of forming the perpendicular magnetic layer, a granular structure layer containing magnetic particles and an oxide with a melting temperature of 1000°C or lower is formed by a sputtering method.
