ABSTRACT:
Additives that inhibit the passage of oil across oil-air interfaces in disk drives and enable the use of the lower viscosity oil in disk drives are disclosed. Mass transfer of oil from the bulk liquid oil into the vapor phase takes place by oil molecules evaporating from the oil-air interface, or collections of oil molecules being ejected from the oil-air interface as aerosol. The invention reduces mass transfer across the oil-air interface through the use of oil-soluble surfactants.
