摘要： A disk clamping device for clamping either one of a disk having a small center hole, such as a compact disk, and a disk having a larger center hole, such as a video disk, to a turntable with which the diameter of the turntable can be increased to reduce the amount of bending and vibration of the disk while it is being played. A first hub (24) for centering a disk (30) having a small center hole is mounted on the disk drive shaft (23) of the drive motor (21), while a second hub (26), separate from the first hub (24), is mounted on the other side of the disk playing position together with a clamper (27). The second hub (26) has a clamping surface (26a) which is brought into contact with the surface of the disk having a small diameter hole when engaged with the disk drive shaft (23).

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： 2.2 Die Erfindung schafft Abhilfe, indem eine Einlegeschei­be (5) in das CD-Fach (2) des CD-Spielers oder der CD-Cartridge (1) eingelegt wird, deren Außendurchmesser dem Hüllkreis­durchmesser der Halterungsvorrichtung entspricht. Der Innendurchmesser ist an den Außendurchmesser der CD kleineren CD-Formats angepaßt, so daß die CD in die Ein­legescheibe hineingelegt werden kann.
2.3 Die CD-Haltevorrichtung ist zum universellen Abspielen von CD's verschiedener CD-Formate auf ein und demselben CD-Spieler anwendbar.

摘要： A disk drive apparatus according to the present invention includes a horizontal guide mechanism and a vertical guide mechanism, which are disposed between a frame (10) and a slider (60) for slidably guiding the slider (60). The horizontal guide mechanism includes an engaging piece (69b) disposed in at least one of the frame (10) and the slider (60) and an engaging hole (24a), which is disposed in the other and is engaged with the engaging piece (69b). One of the frame (10) and the slider (60), in which the engaging piece (69b) is formed, is made of a metallic sheet material while the engaging piece (69b) is formed by bending part of the metallic sheet material.
Forming the engaging piece (69b) by bending part of the metallic sheet material in such a manner simplifies the structure of the disk drive apparatus according to the present invention so that the fabrication is facilitated, enabling fabricating cost to be reduced.
