so data on a surface of the disc is accessible by the head, the head having a head height, wherein the high
capacity data disc is for use with a disc drive in a portable computer, the support assembly comprising:
a hub having first and second axial ends and a flange extending from the second axial end, the flange
supporting the data disc; and
a clamp connected to the hub to rigidly connect the data disc to the hub, the clamp being a thermally
responsive clamp connected to the hub by a thermal shrink fit, the clamp having a first generally annular
portion contacting the data disc and a second generally annular portion extending radially away from the hub
beyond the first annular portion and being spaced from the data disc by a distance greater than the head
height.
