ABSTRACT:
A composite lubricant for recording disk media, a recording disk media including a layer of the composite lubricant, and method of manufacturing the same are described. The composite lubricant may include a non-phosphazene component and a phosphazene component where the non-phosphazene component is a difunctional perfluoropolyether compound terminated with first and second polar end groups, the first polar end group comprising a first number of hydroxyls and the second polar end includes a second number of hydroxyls, greater than the first number of hydroxyls. The phosphazene component may be a difunctional perfluoropolyether compound terminated with a phosphazene functional group and with a third polar end group, the third polar end group comprising a third number of hydroxyls equal to the second number of hydroxyls.
