Abstract

A method of adjusting the tilt of objective lenses in an optical pickup having a plurality of light sources, an optical pickup component with a plurality of objective lenses which converge light from the plurality of light sources on an optical information recording medium and a movable part which holds the plurality of objective lenses, an actuator which drives the movable part of the optical pickup component, and a base on which the actuator is arranged and an optical system which introduces light emitted from the plurality of light sources to the plurality of objective lenses is constituted, which are capable of producing an optical pickup with a plurality of objective lenses while tilt is being simply adjusted, the method includes: a first tilt adjustment step of adjusting the tilt of the plurality of objective lenses with respect to the optical information recording medium with the optical pickup component temporarily arranged at a predetermined position on the base; and a tilt detecting step of detecting the tilt of the plurality of objective lenses after the first tilt adjustment step has been completed.
