A disc holder for holding at least one media storage disc (15) during rotation. The holder comprises a central hub (11) arranged for rotation about a central axis. The hub (11) includes resilient centring arms (18) which are arranged to provide an outwardly directed centring force on an internal bore of a carried disc (15) in order to centre the carried disc about the axis of rotation of the hub. The arms (18) are disposed in, and movable in, planes which are substantially perpendicular to the axis of rotation of the hub. The disc holder may be arranged for carrying a stack of axially spaced media storage discs (15) and may include axial gripping means for holding the stack together. The gripping means comprises a central shaft (17) which is held in position by ball shaped clamps (21) which are spring loaded against inclined surfaces. |
