摘要：

The structure of the interface between a lubricant film and a carbon film on a thin film magnetic recording disk was investigated by TOF-SIMS. Fombiln AM2001, Fomblin Z. DOL and Fomblin Z. DIAC of perfluoropolyether were used for a lubricant, and the sputtering carbon film A was used for a carbon film. It was considered by TOF-SIMS that the terminal groups of Fomblin AM2001 interacted with sp(2) elements of a carbon film, the terminal groups of Fomblin Z. DOL, Fomblin Z. DIAC combined with water elements of a carbon film through hydrophilic combination. The results showed that the lubricant which combined with a carbon film were "Bonded lubricant", the other which not combined with a carbon film were "Free lubricant".
