<p>PROBLEM TO BE SOLVED: To simply keep a balance of disks. SOLUTION: The individual disks 1 are put aside in their prescribed directions by an amt. of a common difference between a hub 2b of a spindle motor 2 and a fixing hole 1a of each disk respectively, and the centroid of the total disks is conformed with the center of the spindle motor. For example, if the disks are two, they should put aside in the diametrically opposite directions to each other by the common difference respectively, and if the disks are three, they should put aside in shifting them at 120 deg. by the common difference respectively.</p> |
