Thermally stabilized perpendicular magnetic recording medium

摘要

A magnetic recording medium including a substrate, and at least one magnetic layer formed on the substrate. The magnetic layer is formed from an alloy containing Cobalt, and Platinum (Pt). The magnetic layer is also formed from grain boundary segregation materials comprising Manganese Oxide and at least one of Silicon Oxide, Chromium Oxide, and Cobalt Oxide (CoO).
