<P>PROBLEM TO BE SOLVED: To provide a turntable capable of reducing local wobbling mainly caused by static electricity generated on an optically recordable and reproducible flexible disk placed on the turntable and performing stable focusing in optical recording and reproduction. <P>SOLUTION: A spacer 104 is incorporated in the turntable 102 provided with through-holes 105 for air flowing, the optically recordable and reproducible flexible disk 101 is placed on the turntable, and they are integrally rotated. In this case, a stable airflow is generated in a gap secured with the turntable 102, force by the airflow, the gravity/centrifugal force of the flexible disk 101 and electrostatic repulsive force are balanced, thereby keeping the stable balanced state of the flexible disk 101. <P>COPYRIGHT: (C)2007,JPO&INPIT |
