Abstract: PURPOSE:To lower the limit of tracking capacity of a reproducing device and to remove wow and flutter easily by eliminating eccentricity engaging the lower edge of the hole of a disk tightly with the part of the same diameter of the conical face of a sliding body. CONSTITUTION:The upper face 5' of a flange 5 is perpendicular to a rotation shaft 2. The diameter of the lower end of the conical face 7 of a sliding body supported slidably by the rotation shaft 2 is larger than the maximum diameter of the hole 3 of a disk 4, and the diameter of upper end is smaller than the minimum hole diameter. The sliding body 6 is energized upward by a spring 8, and upward sliding is restrained by a stopper 9.
