Abstract
A hard-disk drive. The hard-disk drive includes a disk enclosure, a magnetic-recording disk accommodated in the disk enclosure, and a diffusion suppressing film. The diffusion suppressing film divides the space in the disk enclosure into a first space where the magnetic-recording disk is disposed and a second space for retaining a lubricant. The diffusion suppressing film also suppresses diffusion of the lubricant from the second space to the first space.
