The single straight shaft is prevented from being driven out of the hub by providing internal threads at both ends of the straight shaft for engaging first and second screws through the internal threads respectively. The first screw causes a clamper to depress a magnetic hard disc against the hub, the second screw is provided to prevent the single straight shaft from being driven out of the hub. The straight shaft abuts a first and second bearing separated by spacer means disposed under the hub in alignment with the first and second inner races of the first and second bearing.
