ABSTRACT:
The disclosure relates to a lubricant layer formed on the magnetic surface of a magnetic storage medium such as a magnetic disk. Optionally a protective film may be interposed between the magnetic surface and the lubricant layer. Several types of perfluoroalkyl compounds including some polymers have been proved excellent as the lubricating material. The lubricant layer formed of these perfluoroalkyl compounds is remarkably high in durability even though the read/write head makes repeated frictional contact with the storage medium, and this lubricant layer is very low in the tendency to stick to the head.
