PURPOSE: An auto balancer is provided to improve the unbalance by an eccentric mass in a disk operating system. CONSTITUTION: The auto balancer comprises a member for correcting balance of a revolution body and a member for increasing spin of the revolution body. The balance correcting member transfer follow the rotation of the revolution body in the anti-direction of the eccentric mass of the revolution. The spin increasing member increase the whirling of the revolution body by being compressed and being expanded because the centrifugal force follow the rotation of the revolution. Whereby, with increasing whirling force, it is able to reduce unbalance of rotating system.
