In order to achieve the required Contact Start and Stop (CSS) durability in the rigid disk system, we investigated the relationship between CSS durability and lubricant structures in terms of polar group, chain length, and chain symmetry. The stronger polar group which has a strong intensive adhesion on the disk surface, shows the ability to withstand CSS operations. The long saturated hydrocarbon chain group, with both an extensive cohesion and high packing, leads to higher durability. Based on these findings, we designed and synthesized new lubricants which exhibit further improved performance.
