CD player developed as a higher model of Teac RDS-10. Teac's original VRDS (Vibration - Free Rigid Disc - Clamping System) is carried in the mechanism part. In this mechanism, by crimping a disc with a high precision clamper to a high mass turntable having the same diameter as the disc and a delicate taper angle, it corrects the warping and distortion of the disc and thoroughly vibrates and resonates during disk rotation I am eliminating it. Furthermore, it is possible to always read pits at the center of pickup optical axis by means of a pickup finely adjusted at the same angle as the taper angle of the turntable.
In the Teac VRDS-20, aluminum die casting is used for a turntable, and a newly designed wall thickness reinforcing rib structure is adopted as a bridge part supporting this. In this bridge's mechanical base, special polymer material mixed with glass fiber and ceramic powder is adopted as polyester base. In addition to being extremely low in coefficient of thermal expansion and strong in temperature change, this material has about twice the specific gravity compared with ABS resin, it has excellent electrical and mechanical properties, and hard dimension accuracy is possible.High precision helicoid is adopted as a clamping mechanism. In addition, a high precision high torque brushless · hole motor is adopted as a drive motor.
