Abstract: A method and apparatus for polishing hard discs uniformly while minimizing frictional electricity between the discs and polishing materials as well as preventing from frictionally heated deformation. A turntable for placing a disc thereon is freely rotatable without being connected to any motor or other driving force. A polishing material rotates horizontally and polishes the surface of the disc by contacting with the surface. The turntable relatively slides against the surface of the polishing material. A spindle of the polishing material is slightly inclined toward the center of the turntable from a vertical axis of the disc. The turntable is rotated in a direction opposite to the rotating direction of the disc. The rotation of the turntable is induced by the rotation of the polishing material transmitted by the friction between disc and turntable. The disc is substantially electrically connected to the ground during the polishing.
