发明名称 TURNTABLE DEVICE AND MANUFACTURING METHOD THEREOF
摘要 <p>A turntable device includes a disc base on the circumference thereof, and the disc base has a hardness more than a given level. The surface of the disc base is roughened at a given level in order to prevent the disc from slipping and adhesion to the disc base. The disc base can compensate surface wobble caused by the disc base. A manufacturing method of the turntable device includes the steps of: a) dripping liquid resin mixed with fine particles on the circumference of the turntable; and b) hardening the resin to form the disc base. The turntable device is good for e.g. CD players, optical disc driving apparatuses.</p>
