Abstract
A method for creating a hard drive includes installing a slider in a disk drive having at least one disk lubricated with a first stage lubricant. The slider is designed to be in contact with the disk at initial use. The slider is burnished. A second stage lubricant is added to the disk after the burnishing step. The first stage lubricant provides less lubrication than the second stage lubricant, allowing the slider to be burnished in a controllable manner during the burnishing step. The second stage lubricant then provides lubrication to the disk during use by the end consumer.
