To provide a vibration resistance controller for an optical disk drive which does not receive the influence of vibration and impact by more exactly executing the correction of a servo system from a detection signal based on the external vibration detected by a sensor.

The vibration resistance controller of the optical disk drive 1 having a loop for applying feed forward or feed back to a servo system for the position control of an optical head of an optical disk 5 is equipped with a detecting means which is disposed with the displacement sensors A, B in the plural positions advancing to the optical head 6 and detect the external vibration from the phase differences and output changes of these displacement sensors A, B. The optical head control signal of the servo system is corrected from the detection results of the detecting means.
