Abstract

PURPOSE: To improve sliding resistance of a recording medium by supplying a necessary amount of lubricant from a lubricant supply source to the surface of the medium through a lubricant supply system.
CONSTITUTION: Lubricant 14 is supplied from a lubricant supply source of a hollow part 11 of a spindle shaft 5 to the hub groove 13a of a hub 6 through a supply passage 12 by means of centrifugal force generated at the time of operating a head disk assembly, and further supplied to a spacer groove 15a of a spacer 9 laminated and placed on the hub 6. The spacer 9 is formed of a material immersed with the lubricant 14, and the lubricant 14 stored in the groove 15a is gradually oozed to the surface of the inner peripheral side of a recording medium 10 through the spacer 9. The lubricant 14 is moved from the inner peripheral side to the outer peripheral side by means of the force, an air stream. Thus, a lubrication film on the surface of the medium 10 is always maintained suitably to improve its sliding resistance.
