摘要:
A magnetic recording medium including a solid lubricant film containing a plasma-enhanced chemical vapor deposited perfluoropolyether is disclosed. Preferably, the solid lubricant is formed in the presence of oxygen and longer fluorocarbon chain to form perfluoropolyether, thereby enhancing the chain flexibility perfluoropolyether and in the presence of a hydrocarbon to stabilize the process, thereby allowing process control.
