摘要： A disc device capable of achieving a slimming down of a tilt adjusting portion is provided. A tilt adjusting portion 400, 500, or 600 is provided to adjust a light beam 303b emitted from an optical pickup 303 such that an optical axis 303c is set perpendicularly to a disc 200 loaded on a disc turning portion 302. As the tilt adjusting portion 400, 500, or 600, a turntable adjusting portion 600 for adjusting a tilt of the disc loading face of the disc turning portion 302, and an optical pickup adjusting portion 400 or 500 for adjusting a position of a frame 307 that holds an optical pickup driving portion 305 are provided. Therefore, a margin of adjustment in the adjusting portion can be reduced, the tilt adjusting portion 400, 500, 600 can be reduced in size, and a slimming down of a disc device 100 can be achieved.

摘要： Disclosed is an apparatus for reading information recorded on th e 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 forces, which are present when rotation the data carrier (1), are able to level the data carrier (1), thus reducing the wobble.

摘要： There is provided a low-cost disc device capable of using the same spindle motor and clamper even when the type of the DVD disc device differs. The clamper (100) includes a clamper main body (104) and positioning sections. A disc (10) is sandwiched between the clamper main body (100) and the spindle motors (210, 220, 230) holding the disc (10) and rotating. The positioning sections are formed on the clamper main body (104) for deciding the radial-direction relative position of the spindle motors (210, 220, 230) with respect to the clamper main body (104).
