Dynamic conformations of fluorocarbon molecules on magnetic hard disk surfaces with charged sites

摘要: To meet the demand of extremely high recording density magnetic storage device, head is expected to reduce its flying height sub 5 nm. Lubricant films in such system become more important and conformation characteristics lubricant molecules, which receive attractive forces both from disk head, must be clarified for stable head. In this report molecular dynamics simulations are carried out investigate molecules. The model composed solid surface polar-ended fluorocarbon has several reactive sites, interact with polar end groups Varying number processes that sites attract molecules simulated. Results present indicate tend gathered piled up. It difficult achieve 100% coverage.
