Abstract

Current hard disk drives use hydrocarbonbased oils to lubricate the actuator arm pivot and the fluid dynamic bearing spindle motor At elevated drive temperatures hydrocarbon oil molecules escape from the fluid dynamic bearing motor and pivot actuator by evaporation and aerosoling entering into the drive air stream and contaminating the head–disk interface In this paper we study the transfer mechanism of hydrocarbon molecules nalkane C24H50 and C36H74 and disk lubricant ZdolPFPE molecules at the head–disk interface using molecular dynamics simulation A “twostep” transfer mechanism is postulated Airborne hydrocarbon molecules condense first onto the disk surface and then transfer by evaporation to the slider surface The numerical results obtained are in agreement with the assumed hypothesis of the transfer mechanismWe would like to thank Prof Vlado Lubarda and Prof Gaurav Arya for their valuable advice in the modeling of hydrocarbon and lubricant transfer simulation We would also like to thank Western Digital for providing an internship opportunity for Young Woo Seo in San Jose
