Abstract
Turntable runout of an optical disk drive is corrected by the application of at least three skidproof rubber pads affixed to the turntable on a circle and separated by equal angles. The height of each of the skidproof rubber pads is selected to adjust the runout of the turntable at each location. The invention accomplishes the compensation of turntable runout where, traditionally, lathe-turning was required.
