摘要： A video disc player is provided with a stabilizing disc which during playing is disposed at a small distance above the video disc, air being admissible through an inlet restriction between the stabilizing disc and the video disc so that locally a sub-atmospheric pressure is produced as a result of the centrifugal pumping action of the video disc. In order to prevent the video disc from being drawn along when the stabilizing disc is moved upwards, an air by-pass passage is provided which via air-valve means can be opened when playing of the video disc is terminated, so as to admit an increased air stream between the stabilizing disc and the rotating video disc in order to at least substantially eliminate the prevailing sub-atmospheric pressure.
摘要翻译：视频盘播放器设置有稳定盘，其在播放期间设置在视频盘上方较小的距离处，空气通过稳定盘和视频盘之间的入口限制允许，使得局部地产生次大气压力作为视频盘的离心泵送动作的结果。为了防止视频盘在稳定盘向上移动时被拉出，提供了一个空气旁路通道，当播放视频光盘终止时，通过空气阀装置可以打开，以便允许在稳定盘和旋转视盘之间增加空气流，以便至少基本上消除主要的低于大气压的压力。
