摘要：
A highly reliable rotary magnetic recording medium has a lubricating film layer on its surface, the lubricating film layer being composed of fluoropolyether having at least two acidic functional groups in one molecule as a lubricant and fluoropolyether having at least two basic functional groups in one molecule as another lubricant, where a stable network structure is formed on the surface of the magnetic recording medium by an appropriate combination of the lubricant having the acidic groups at the terminal ends of lubricant molecule and the lubricant having the basic groups at the terminal ends of lubricant molecule.
