Abstract :
Contact recording systems have been studied for future surface recording disks with a high recording density. Ultra-low spacing technologies for ultra-low spacing are required for the contact systems as well as high wear performance. Particularly, a liquid lubrication system plays an important role for reducing a mechanical spacing and for improving wear performances. In this study, molecular design of lubricants for contact systems will be discussed from a viewpoint of bouncing and wear behaviors. As a result, a minimum bouncing height of 3 nm and a high wear performance were obtained.
