Abstract: PROBLEM TO BE SOLVED: To improve a degree of flatness at the time of rotating an optical disk by attaching a weight on the strained part of the face of the optical disk and correcting the strained part of the face of the optical disk with the component of a centrifugal force to be exerted on the weight at a use time which is vertical to the face of the optical disk. SOLUTION: An optical disk 1 is set on a rotary driving device 3 and the displacement of the face of the optical disk 1 with respect to a reference plane is measured by using a laser displacement meter 4 while rotating the disk 1. The position of a strained part is detected as an angle with respect to the reference line M provided in the radial direction of the disk 1 and a weight 2 is added on a region where the strain specified by this measurement is generated. Here, the whole of the face of the disk is brought into to be in a flat state by attaching the weight 2 at a position where the displacement amount from the reference plane becomes maximum in the peripheral direction and by exerting a force directing to the reference plane direction on the disk at the time of rotating the disk 1. Moreover, the mass of the weight 2 is deteremined by the magnitude of the strain.

Abstract: PROBLEM TO BE SOLVED: To correct the deviation of the centroid of an optical disk. SOLUTION: The circumferential position B and magnitude of unbalance due to the mass eccentrity of the optical disk 1 manufactured in a normal process are detected. The position B is detected as an angle M with respect to a reference line A provided in the radial direction of the optical disk 1 Next, the mass eccentricity of the optical disk 1 is corrected by adding a weight 2 for negating the detected unbalance. At this time, the mass eccentricity is easily and accurately corrected if balance is achieved by adding the weight on the radius C including a point which is symmetric with the deviated positon of the center of gravity with respect to a central point 0 of the optical disk 1.
