Abstract
A disk storage has one or more disks provided with center holes. An electric motor extends coaxially through these holes and has an external rotor to the outer circumference of which the disks are secured so that they rotate with the rotor. A labyrinth seal is provided for at least reducing the escape of contaminants from the motor.
