High density information discs are lubricated with a silyl quaternary ammonium salt of the formula <IMAGE> wherein R is a lower alkyl group of 1-5 carbon atoms; R3 is methyl or ethyl; R4 is an alkyl group of 1-12 carbon atoms and X is -OSO2-(CH2)nCH3 wherein n is an integer of 5-12. Discs lubricated with this lubricant exhibit improved stability to high temperature, high relative humidity environments.
