A skew adjustment system of an optical disk device is provided to readjust radial skew for the optical disk device once misalignment of the radial skew is detected while displaying detected and readjusted states for the misalignment of the radial skew, thereby improving a product throughput. A skew adjustment jig unit(204) adjusts tangential skew and radial skew for an optical disk device, and readjusts the radial skew if misalignment of the radial skew is detected. A radial skew misalignment detector(206) detects misalignment of the radial skew for the disk device whose skew is adjusted. If the misalignment is not detected, a performance test module unit(210) receives the disk device from the detector(206) to carry out a performance test. A controller(202) provides a control signal for adjusting the tangential skew and the radial skew for the disk device as well as a control signal for readjusting the misalignment, to the jig unit(204), provides a control signal for detecting the misalignment to the detector(206), and provides a control signal for conducting the performance test to the module unit(210) if the misalignment is not detected.
