Abstract
PURPOSE: To prevent both the wear and the damage on the surface of a magnetic disk and thus increase the lifetime of a magnetic disk device, by avoiding the exhaustion of the lubricant on the surface of the magnetic disk.
CONSTITUTION: A magnetic disk 3A consists of a porous layer 9 provided at the center part of a disk substrate 4 and filled with the liquid lubricant, a coated layer 10 formed by applying the plating or sputtering process on the surface excluding an outer peripheral part 9A of the layer 9, a magnetic film 5 formed on the surface of the substrate 4 excluding the layer 9, and a lubrication layer 6 formed on the surface of the film 5 by the liquid lubricant. Such disk 3A is fixed to a spindle 2, and thus the liquid lubricant stored in the layer 9 oozes out gradually from the part 9A according to the rotation of the disk 3A and by the centrifugal force.
