Abstract
A disk storage drive for mounting and driving at least one hard magnetic storage disk in a contaminant-free chamber is provided. A motor of the drive includes a stator, a bearing system, a rotor casing mounted to rotate around the periphery of the stator and a mounting arrangement for mounting the motor and disk in the contaminant-free chamber in a manner which minimizes the transfer of contaminants from the stator and bearing system into the contaminant-free chamber.
