Estimating the term…
A magnetic disk device includes a plurality of disk-shaped magnetic disks, a spacer, a hub, and a clamp. Each of the magnetic disks includes a through-hole in a center section thereof. The spacer is disposed among the magnetic disks, and includes a through-hole in a center section thereof. The hub is inserted into the through-holes of the magnetic disks and the spacers. The clamp presses and holds the magnetic disks and the spacer. At surfaces where the magnetic disks and the spacer or the clamp contact, a flat surface height of an upper surface of at least one magnetic disk that contacts an outer circumference of the spacer or the clamp is lower than a flat surface height of the upper surface of at least one magnetic disk of the magnetic disks that contacts an inner circumference of the spacer or the clamp.
