发明名称 Assembly method of optical pickup and optical pickup apparatus
摘要 A method for assembling an optical pickup apparatus for recording/reproducing a high density DVD, DVD and CD including two objective lens and three laser light sources, the objective lenses being provided on the lens holder having an actuator base for supporting the actuator, the method for assembling the optical pickup apparatus comprises the steps of adjusting a first tilt angle of the actuator base so that a coma aberration of a spot formed by the first light beams decreases when the first light beams are converged onto the first recording medium via the first objective lens, and adjusting a second tilt angle formed between the second objective lens and the lens holder so that a coma aberration of a beam spot formed by the second light beams decreases when the second light beams are converged onto the second recording medium via the second objective lens.
