<p>A unitary centering device made of a pliant material is interposed between a cylindrical spindle and a plurality of annular disks in a disk drive. The centering device is corrugated to provide spaced-apart radial spring forces to hold the disks concentrically on the spindle during the assembly process. The corrugated shape also ensures that an air gap exists between the disks and the spindle, so that temperature cycling during operation does not result in radial disk shifting.</p> |
