Abstract
A method and apparatus are provided for improving the durability of lubricating layers on the surfaces of disks. The lubricating layers on the disks are exposed to ultraviolet and infrared radiation of sufficient duration and energy to reduce the total thickness of the layer but retain at least about 40% of the thickness of the remaining layer in bonded form. The useable lifetime of the lubricating surface is prolonged by treatment of the lubricating layer in this manner.
