ABSTRACT:
Disclosed is an apparatus for reading information recorded on the track of a data carrier (1). The apparatus comprises rotating means (2) for supporting and rotating the data carrier (1) around an axis of rotation (3). The rotating means (2) comprises a turntable (21) and a motor (23) for rotating the turntable (21). The apparatus according to the invention is able to suppress a wobble introduced by the data carrier (1) when rotated. This is done by a flexible part (24) in the rotating means (2). In an embodiment the supporting surface of the turntable (21) comprises the flexible part (24). This allows the data carrier (1) to tilt in radial and tangential direction. The centrifugal force which are present when rotation the data carrier (1), are able to level the data carrier (1), thus reducing the wobble.
