Abstract

After the application of a lubricant, magnetic disks are exposed to low-energy X-radiation causing a reaction in the lubricant and forming a solid fluorine compound on the disk surface. In an example, the magnetic disks are exposed for a short time to an X-radiation of 0.01 to 0.1 MeV immediately after the lubricant has been applied. During this process, only the start-stop zones or the entire disk surface may be radiated. The homogeneously distributed solid fluorine compound, formed on the disk surface during radiation, yields an excellent head/disk performance. This, in turn, leads to a longer start/stop life and fewer head/disk assembly failures caused by head/disk interference.
