The figure shows a magnetic disk assembly for use in disk storage apparatus. A number of disks 1, each in the form of an annular ring, are assembled with accurately machined intervening spacer rings 2 on a hub 3. The hub 3 is itself supported for rotation on spindle 4. The lowest disk sits directly on annular shoulder 5, accurately machined so as to provide a datum surface for the disks.
