Corrosion resistance of next generation magnetic disk (2): Synthesis and properties of novel lubricant for magnetic disk towards improved anti-corrosion

摘要

Novel lubricant with corrosion inhibiting benzotriazole groups was designed and synthesized to secure reliability of next generation bit patterned media (BPM). The novel lubricant exhibited excellent anti-corrosion ability compared to those of the conventional lubricants. Furthermore, the novel lubricant could be a good candidate for thermal assisted magnetic recording (TAR) because of its high thermal durability.
