Abstract
A disk drive for driving storage disks can suppress warping of the disks even when thinner disks and a less rigid hub are employed for the purpose of reducing the size of the disk drive. The disk drive includes a plurality of disk-type storage media, spacers placed between respective two adjacent disk-type storage media, a hub on which a stack of the disk-type storage media and the spacers is fitted, the hub having a surface contacted by the disk-type storage medium positioned on one end of the stack, and a clamp which presses the stack onto the surface of the hub.
