Abstract

A hub assembly for a data storage disk comprises a hub member and a raised boss near a center axis of the hub member, the raised boss being surrounded by an annular bonding surface and being configured so as to protrude into a center hole of a data storage disk when the bonding surface is in contact with a surface of the disk. Two hub assemblies are disposed on opposite sides of the disk, the respective raised bosses of the hub assemblies protrude into a center hole of the disk, where they are bonded to each other to increase the overall bonding force between the hub assemblies and the disk. The hub assemblies and disk may be bonded together using a UV curable adhesive. The hub assembly may also include a metal hub plate that is used to magnetically clamp the disk/hub assembly to the spindle of a disk drive. In one embodiment, the metal hub plate has several tabs that are bent around the disk to attach the metal hub plate to the disk. The metal hub also has features, such as notches, that are used to register the metal plate correctly with a die that is used in the process of bending the metal tabs.
