Abstract

In the past, various types of lubricants have been used for magnetic surfaces such as disks and tapes. It has been found that in many cases improved lubricating properties may be obtained by the addition of additives, particularly those additives regarded as load-bearing, to the base lubricants.

Additives for Lubricants of Magnetic Surfaces

In the past, various types of lubricants have been used for magnetic surfaces such as disks and tapes. It has been found that in many cases improved lubricating properties may be obtained by the addition of additives, particularly those additives regarded as load-bearing, to the base lubricants.

Useful base lubricants include silicone, fluorinated silicone oils, mineral oils, isoprenoids, fluorenated and chlorofluorinated compounds, diester lubricants, polyalkyleneglycols, oleic acid and polyphenylethers.

Additives suitable for use with these base lubricants include tri-cresyl phosphate, dilauryl phosphite, triphenyl tetraphosphates, tri-p-tolyl phosphate, dihydroxy phosphines, benzyl disulfide, phenyl disulfide, zinc dialkyldithiophosphate and triphenyl arsenine.
