Patent number: 5633089Abstract: There is provided a lubricant which is produced by dissolving a sorbitan ester compound in a solvent such as hexane or toluene. In the sorbitan ester compound, at least one of hydroxyl groups of 1,5-sorbitan is linked by ester linkage to a perfluoro polyether having a terminal carboxyl group and at least an other hydroxyl group is linked by ester linkage to a hydrocarbon having a terminal carboxyl group. There is also provided a thin magnetic metal film type magnetic recording medium or a coated magnetic recording medium in which the above lubricant is held on the surface of a magnetic layer. The lubricant exhibits superior lubricating effects under all conditions and is capable of maintaining the lubricating effects for prolonged time. Consequently, the magnetic recording medium which has the lubricant held on the magnetic layer exhibits superior running durability and resistance against abrasion.Type: GrantFiled: September 22, 1995Date of Patent: May 27, 1997Assignee: Sony CorporationInventor: Hirofumi Kondo
