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 sp2 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”.
