摘要：
A method for manufacturing a magnetic recording medium includes forming a first protective layer of first material over a magnetic film provided on a substrate. The first protective layer has a thickness of about 0.2 nm to about 2 nm. A second protective layer of second material is formed over the first protective layer by driving ions of the second material into the first protective layer. The first protective layer is configured to prevent the ions of the second material from penetrating into the magnetic film.
