It has been shown that polymer magnetic binder systems used in magnetic recording disks can be cured by electron beam. Ultraviolet (UV) curing of siloxanes has shown signs of modification to polymer surface when exposed to UV light between 185 - 250 mm radiation. Some current disk formulations are strong absorbers of UV due to their composition. The lubricant used on some of these disks contains (Image Omitted) type bonds. There is sufficient energy in the 180 to 250 mm region to form free radicals, which, in turn, can react with the disk coating to anchor a lubricant to the disk, thus preventing start-stop failures due to lubricant depletion. A further advantage would be the formation of a highly cross-linked surface on the disk.
