OPTICAL DISK DRIVE, CAPABLE OF RECORDING/REPRODUCING INFORMATION ON/ FROM AN OPTICAL DISK HAVING A STANDARD SIZE AS WELL AS A MICROMINIATURE OPTICAL DISK USED IN A MOBILE APPARATUS

摘要

PURPOSE: An optical disk drive is provided to form the second turn table for a microminiature optical disk except the first turn table for an optical disk having a standard size, and to rotatively drive the second turn table by a dynamic force transmitter, thereby recording/reproducing information on the standard-sized optical disk and the microminiature optical disk as well. CONSTITUTION: The first rotational axis(130) is formed for a spindle motor. The first turn table(131) is coupled with the first rotational axis(130) to set an optical disk therein. A dynamic force transmitter(140) transmits a rotational driving force of the first turn table(131) to the second turn table(151). The second rotational axis(150) receives the rotational driving force of the first rotational axis(130) by the dynamic force transmitter(140). The second turn table(151) is coupled with the second rotational axis(150).
