Surface lubrication of magnetic tapeFriction minimization between magnetic media (tape, cards, drums, etc.) and magnetic transducer (heads, etc.) is a key requirement in recording systems. Results are presented for an investigation intended to eliminate previously encountered shortcomings of friction-reducing treatments by a deposition of an inert liquid film on a fully manufactured (cured) magnetic medium. The film contains no particles, represents a compound characterized by good lubricating and thermal properties, is inert with respect to the normal formulation constituents, and has low surface tension and vapor pressure characteristics. The deposited film need only be molecularly thin to impart adequate lubricating properties to the tape. The discussion covers the characteristics of the surface lubricant, method of application, and surface coated magnetic media test results. Greater than 5 million passes of the 3M 900 tape on a loop tester are achieved with no apparent effect on the tape and with head wear decreased by as much as a factor of ten
