ABSTRACT:
A method and apparatus for disc position centering is disclosed. The invention is adapted to precisely position the center of a disc at a predetermined position, in relation to the disc's outer diameter, when the allowable variation of the absolute value of the outer diameter is larger than the degree of centering precision required. The apparatus is adapted to determine the outer diameter of the disc using a displacement measuring device, and data provided to the system computer. The apparatus then positions the disc to the desired center position using devices which grip the disc by its outer periphery and whose relationship to the desired center position is known.
