| description | PROBLEM TO BE SOLVED: To provide an optical recording/reproducing device capable of adjusting a tilt with a jitter amount of a regenerating signal, a tilt adjusting method suited to it and a recording control method. SOLUTION: This device is provided with an optical pickup 20 containing an objective lens, a tilt adjusting means adjusting the tilt of the objective lens, a jitter detection means 34 detecting the jitter amount of the regenerating signal generated from the optical pickup 20 and a tilt control part 36 feeding back the jitter amount detected from the jitter detection means 34 to the tilt adjusting means and controlling so that the jitter amount becomes minimum. Thus, since the need to provide a displacement sensor 26 detecting the tilt of the optical pickup 20 opposite to a disk is eliminated, this device isn't limited by a setup space. |
