Advanced Head Disk Interface System Assisted by Gas PFPE Lubrication
An advanced head disk interface (HDI) system assisted by gas perfluoropolyether (PFPE) lubrication is discussed in this paper.It is known that lubricant spins off at a high rotation speed and high temperature.Lubricant redistribution after long-term seeking operation with near-contact flying has been studied.The spin-off and redistribution of lubri
