ABSTRACT:
According to the invention, a disk drive includes structure that prevents a non-operational shock from damaging a data region of a disk surface as a result of contact between the data region and other components of the disk drive. The disk drive includes one or more retaining structures, each retaining structure having portions that extend, above and below the disk, respectively, from a location beyond the periphery of the disk to a location within the periphery of the disk, but outside of the data region of the disk surface. The one or more retaining structures limit displacement of the disk in a direction perpendicular to the surface of the disk to prevent the data region from contacting other components of the disk drive, thereby preventing damage to the data region.
