Figure 1 is a configuration diagram of one embodiment of the disc vibration damping mechanism according to the present invention, Figure 2 is a plan view of the damping material used in the present invention, and Figure 3 is a diagram of the disc vibration damping mechanism shown in Figure 1. Figure 4, an enlarged view of the main part, shows the state of deformation that the optical disc recording medium undergoes when the gap between the stabilizer and the optical disc recording medium is set to less than the thickness of the damping material in the main part shown in Figure 3. The diagram shown in FIG. 5 is a vibration frequency characteristic diagram of the outer periphery of an optical disk recording medium when the disk vibration damping mechanism according to the present invention is used.
Fig. 6 is a diagram showing the deformation of the damping material when a film etc. cannot be attached to the damping material, Figs. 7 and 8 are block diagrams of the conventional disc vibration damping mechanism, and Fig. 9 is the vibration damping mechanism. FIG. 10 is a vibration frequency characteristic diagram of the outer circumference of the optical disc recording medium when there is no gap between the stabilizer and the optical disc recording medium in the disc vibration damping mechanism shown in FIG.
Figure 11 is a vibration frequency characteristic diagram when the disk vibration damping mechanism shown in Figure 8 is held down by only soft damping material, and Figure 12 is a vibration frequency characteristic diagram when the disk vibration damping mechanism shown in Figure 8 is held in place by a hard damping material. A diagram showing the state of deformation of the optical disk recording medium when it is strongly clamped.
