Abstract
A magnetic recording medium that includes a substrate, an insulation layer applied onto a surface of the substrate, and a magnetic layer applied onto the insulation layer. The insulation layer is made from a redox-corrosion-inhibiting material. In one embodiment, the insulation layer inhibits redox corrosion by inhibiting electron transfer through the insulation layer (e.g., inhibits electron transfer between the substrate and the magnetic layer).
