PROBLEM TO BE SOLVED: To make always excellent recording/reproducing performable without depending on the tilting angle of an optical disk by correcting the effect of wave front aberration. SOLUTION: This optical information recording/reproducing device for recording/reproducing information to/from an optical disk 4 is provided with a laser diode 1 for radiating a laser light to the optical disk, a detecting means 13 for detecting the tilting angle of the optical disk, an aberration correcting means for correcting a wave front aberration caused by the tilting angle by correcting the tilting angle of the optical disk, a driving means for driving the aberration correcting means based on the detected tilting angle, and a laser control means 24 for changing the power of the laser based on the detected tilting angle. |
