    • An optical disc drive for reading the recorded data on an optical disc is provided. The optical disc drive includes a chassis, a turntable and a pickup head. The inner top surface of the chassis has a protruding structure or an escape-prevention component. The turntable is disposed inside the chassis for holding and rotating the optical disc. The protruding structure or the escape-prevention component is located above the optical disc when the optical disc is placed onto the turntable inside the chassis. The movable pickup head is disposed inside the chassis for reading the data recorded on the optical disc. The protruding structure or the escape-prevention component shortens the distance between the top surface of the optical disc and the inner top surface of the chassis. Thus, the optical disc is prevented from escaping from the turntable when the optical disc drive vibrates due to an external force.
    • 提供了用于读取光盘上的记录数据的光盘驱动器。 光盘驱动器包括底盘,转盘和拾取头。 底盘的内顶表面具有突出结构或防止逃逸部件。 转盘设置在底盘内,用于保持和旋转光盘。 当光盘被放置在机架内的转盘上时,突出结构或防脱组件位于光盘上方。 可移动拾取头设置在机架内部,用于读取记录在光盘上的数据。 突出结构或防止逃逸部件缩短光盘的顶表面和底盘的内顶表面之间的距离。 因此,当光盘驱动器由于外力而振动时,防止光盘从转台逸出。
