Laser-assisted in-situ fractionated lubricant and a new process for surface of magnetic recording media

摘要

A magnetic recording medium is formed with enhanced tribological performance by applying a raw, unfractionated lubricant having a wide molecular weight distribution over a disk surface and treating the deposited lubricant with a laser light beam to effect in-situ fractionation of the lubricant to a very narrow molecular weight distribution. Embodiments of the present invention also include laser treating a deposited lubricant to increase the thickness of the bonded lube layer.
