Abstract: Turntable (10) has a turntable bottom (19) and a turntable wall (20) which together define a locating space (21) in which the hub (7) of an information disc is engageable, and in which it is centered by means of a centering member (12) and clamped by magnetic clamping means. At the circumference of the locating space a centering wall (26) is provided, which wall has an inwardly sloping surface (27). The dimensions of the various parts, the field strength of the magnetic means and the coefficients of friction of the cooperating materials of the hub and the turntable are selected in such a way that, once an information disc has reached a position in which the free end of the centering member (22) has engaged the centering hole (17) of the information disc, the outer wall (28) of the hub (7) is situated above the sliding surface (27) of the turntable.
