Abstract
A magnetic disk storage apparatus includes an air-tight enclosure containing a drive mechanism for rotating magnetic disks coated with a lubricant material and a flying head assembly. A lubricant evaporating source is arranged inside the enclosure and exposed to the flow of hot air produced by rotation of the disks whereby the lubricant is evaporated and the enclosure is filled with lubricant vapor to suppress the evaporation and consumption of the lubricant layers coated on the magnetic disks. The lubricant evaporating source may be positioned on the inside wall of the enclosure, on a dummy surface of the disks, or on a portion exposed to the circulating hot air flow inside the enclosure. The surface on which the lubricant evaporating source is coated may be of a porous or rough structure to accelerate the evaporation of the lubricant of the source and provide a strong adhesion of the lubricant material to the surface.
