    • A disc cleaning device is disclosed which includes a disc support platform mounted to rotate about a first axis. This platform is adapted to support a disc to be cleaned and to center the disc to be cleaned about the first axis. An annular cleaning surface is mounted to rotate about a second axis spaced from the first axis. This cleaning surface is positioned to contact a disc to be cleaned supported on the platform. The platform and the cleaning surface are rotated such that the cleaning surface rotates at twice the angular velocity of the platform. The cleaning surface defines an effective radius equal to the separation between the first and second axes. It has been discovered that this geometry and arrangement of velocities ensures that relative movement between the cleaning surface and the disc to be cleaned is oriented substantially radially with respect to the first axis in order to provide a substantially radially oriented cleaning of at least an annular portion of the disc to be cleaned. Certain preferred embodiments include a mechanism for moving any selected one of two cleaning discs into the preferred geometry in order to allow a sequential washing and drying action with separate cleaning discs.
    • 公开了一种盘清洁装置,其包括安装成围绕第一轴旋转的盘支撑平台。 该平台适用于支撑要清洁的光盘并使待清洁的光盘围绕第一轴线居中。 安装环形清洁表面以围绕与第一轴线间隔开的第二轴线旋转。 该清洁表面被定位成接触被支撑在平台上的要清洁的盘。 平台和清洁表面被旋转,使得清洁表面以平台的角速度的两倍旋转。 清洁表面限定等于第一和第二轴之间的间隔的有效半径。 已经发现,这种几何形状和速度的布置确保了清洁表面和待清洁的盘之间的相对运动相对于第一轴线基本上径向地定向,以便提供至少一个环形部分的基本径向取向的清洁 的待清洁的光盘。 某些优选实施例包括用于将两个清洁盘中的任何选定的一个移动到优选几何结构中的机构,以便允许使用单独的清洁盘进行顺序的洗涤和干燥操作。
