Lubrication is a significant step in establishing long-term reliability of disk storage devices. Failure resulting from unlubed or low-lubed disks and lube spin-off is well known. Lube losses are observed during field use of the devices. Both the initial lube retention quality and the lube holding quality of the disks during operation depend on the surface morphology and topography The described method increases both of these parameters significantly. A microwave process is described briefly below. This process consists of microwave radiating either side of a buffed and washed disk for 30 seconds, thus removing any residual fluids from the pores prior to lubing. This increases the lube retention and, more importantly, the lube-holding quality of the disk.
