ABSTRACT:
The present invention includes a data disc support assembly for supporting a data disc relative to a head so data on a surface of the disc is accessible by the head. The support assembly includes a hub which has first and second axial ends and a flange extending from the second axial end. The flange supports the data disc. A clamp is connected to the hub to rigidly connect the data disc to the hub. The clamp has a first generally annular portion contacting the data disc and a second generally annular portion extending axially away from the hub beyond the first annular portion. The second annular portion is spaced from the data disc by a distance greater than the height of the head.
