A disc drive cartridge arrangement includes a hub clamp for engaging a spindle of a disc drive which clamp has inwardly spiralling fingers to reduce the space required therefor and to firmly engage the spindle, and a door and aperture arrangement which allows the heads of the disc drive to enter the cartridge from the upper and lower surfaces of the cartridge. The hub to which the disc of the disc drive cartridge arrangement is mounted includes a labyrinth seal arrangement for preventing contaminants from entering the interior of the housing.
