The invention relates to a turntable (1) for a disc-shaped information carrier (2), such as a DVD, having a central round opening (21). The turntable comprises a centering element (3, 4), which is rotatable about an axis of rotation (7) by means of a driving element. The centering element (3, 4) comprises a fixed centering member (3) having a supporting surface (8) for the information carrier, and a further centering member (4) for final centering of the information carrier, said further centering member being movable in axial direction along the axis of rotation between an upper position, in which the centering member is unloaded, and a lower position, in which the centering member is loaded. An end-centering portion (32) of the movable centering member has the shape of a first truncated cone, which is directed upwards and which has a first apex angle. The turntable is further provided with a pressure member (5) for pressing the information carrier onto the support surface, as a result of which the movable centering member is moved from the upper position to the lower position. The turntable is used in a player for reading and/or writing disc-shaped information carriers having a central round opening, such as a CD or DVD player.
A turntable for a disc-shaped information carrier having a central round opening, comprising a centering element which is rotatable about an axis of rotation by means of a driving element, characterized in that the centering element comprises a fixed centering member having a supporting surface for the information carrier, and a movable centering member for final centering of the information carrier which is axially movable along said axis of rotation between an upper, unloaded position and a lower, loaded position, with an end centering portion of said movable centering member being in the form of an upwardly extending, first truncated cone having a first apex angle, and in that the turntable is furthermore provided with a pressure member for pressing the information carrier onto the supporting surface, as a result of which the movable centering member moves from the unloaded position into the loaded position.
