Lubricant composition and method
 A thin-film magnetic recording disc for use with a read/write head in a disc drive is disclosed. To reduce the static and dynamic frictional coefficients of the disc surface, the disc is coated with a lubricant layer composed of a mixture of a polyphenoxycyclotriphosphazene lubricant and a perfluoropolyether oil. Also disclosed is a lubricant composition containing these two components, as well as a method for improving the lubricating properties of a perfluoropolyether oil.
