ABSTRACT:
Method and device for controlling an optical recording/reproducing device, for detecting a wobble signal in advance during free running when only a focus servo is turned on, carrying out wobble PLL, detecting the present rotating speed of the optical disk from the wobble signal, and controlling the spindle to reach to a target speed quickly, thereby stabilizing the servo in advance before regular data recording/reproduction, and enhancing performance of the optical recording/reproduction device.
