摘要:
A magnetic disc is provided with a magnetic layer, a protection layer and a lubrication layer in this order on a substrate. After successively forming the magnetic layer and the protection layer on the substrate, the protection layer is exposed to plasma under normal pressure, then, the lubrication layer is formed on the protection layer. The plasma is generated in at least one kind of gas selected from among nitrogen gas, argon gas, oxygen gas, and fluorine hydrocarbon gas. The protection layer is a hydrogenated carbon protection layer.
