Perpendicular media with Cr-doped Fe-alloy-containing soft underlayer (SUL) for improved corrosion performance

摘要

A perpendicular magnetic recording medium having a substrate, a Cr-doped Fe-alloy-containing underlayer containing about 8 to 18 at % Cr and a perpendicular recording magnetic layer, and a process for improving corrosion resistance of the recording medium and for manufacturing the recording medium are disclosed.
