Patent ID: 7848186

Claim:
A method of manufacturing an optical pickup apparatus including an objective lens focusing light emitted from a light source onto an information surface of an optical disc, the method comprising: assembling an optical block configured to cause light emitted from the light source to be incident on a first lens surface of an objective lens that includes the first lens surface on a light-source side, a second lens surface on an optical-disc side, a first edge surface provided on an outer region of the first lens surface, and a second edge surface provided in an outer region of the second lens surface, wherein a first optical axis of the first lens surface coincides with a second optical axis of the second lens surface, and wherein the first optical axis and the second optical axis are orthogonal to the second edge surface but not the first edge surface; adjusting a tilt of the optical block so that an optical axis of light caused to be incident on the first lens surface of the objective lens from the optical block becomes orthogonal to a predetermined reference surface; assembling an actuator being configured to drive the objective lens, and including a lens holder with a lens receiving surface, the lens holder configured to hold the objective lens such that the first edge surface of the objective lens is placed on the lens receiving surface; mounting the actuator on the optical block having a tilt relative to the reference surface; and adjusting a tilt of the actuator so that the second edge surface of the objective lens held in the lens holder becomes parallel to the reference surface.
