The optical information recording and reproducing apparatus tilt adjustment method of the objective lens, the manufacturing method of the optical pickup, the tilt adjustment device of the objective lens, the optical pickup parts, and the optical pickup,

摘要

And a plurality of objective lenses for focusing the optical information recording medium a plurality of light sources makes it possible to manufacture while performing adjustment tilt easily, the optical pickup having a plurality of objective lenses, the light from the plurality of light sources an actuator for driving an optical pickup device having a movable body that holds the objective lenses of the plurality of the movable body of the optical pickup parts, the actuator is disposed, the plurality of light emitted from the plurality of light sources in the optical pickup optical system for guiding the objective lens has a configured base, and a tilt adjusting method of the objective lens, the state of being temporarily placed the optical pick-up component to a predetermined position of the base on at a tilt adjustment process first adjusts the inclination with respect to the optical information recording medium of the plurality of objective lenses, a tilt detection step of detecting a tilt of the objective lens of said plurality of tilt adjustment step is completed after the first I was equipped with.
