| 发明名称 | Magnetic recording medium | ||
| 摘要 | A magnetic recording medium is disclosed which has excellent corrosion resistance, even with a protective layer of thickness 2 nm or less. The magnetic recording medium includes, on a substrate, a magnetic layer and a carbon-based protective layer. The thickness of the carbon-based protective layer is 2 nm or less, and the contact angle of water on a surface of the carbon-based protective layer is 25° or greater and less than 60°. | ||
