<P>PROBLEM TO BE SOLVED: To reduce local wobbling mainly caused by static electricity generated on an optically recordable and reproducible flexible disk placed on a turntable and to perform 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 |
