  • Lubricant film forming method, slide body with lubricant film, magnetic recording medium, magnetic head slider, and hard disk drive
    Publication number: 20080024923
    Abstract: A lubricant film forming method has a step of irradiating a lubricant with an OH group laid on a surface of a base material, with infrared laser light that excites vibration of an OH bond of the OH group. In this method, the irradiation with the infrared laser light excites vibration of the OH bond of the OH group in the lubricant. Therefore, it enhances reactivity between the OH group of the lubricant and the surface of the base material, facilitates chemical bonding of the lubricant to the surface of the base material, and enhances durability of the lubricant.
