PERPENDICULAR MAGNETIC RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To realize the enhancement of medium functions such as high output and low noise by improving the orientation of a magnetic recording layer in a perpendicular magnetic recording medium and reducing the initial growing layer in the magnetic recording layer. SOLUTION: The perpendicular magnetic recording medium having a base layer, the magnetic recording layer, a protective film and a liquid lubricating layer on a non-magnetic substrate is characterized in that the base layer includes non-magnetic NiFeCr.
