Abstract
An optical pickup apparatus () is provided with: a carriage body (); an optical parts accommodation module () mounted on said carriage body and accommodating at least (i) a light beam emitting portion () for emitting a light beam, (ii) a light beam receiving portion (), (iii) a beam splitter () and (iv) a grating () for generating a sub beam for a tracking adjustment out of the light beam emitted from said light beam emitting portion; and a grating adjustment mechanism () for rotating said optical parts accommodation module. The optical parts accommodation module is mounted on said carriage body in such a condition that said optical parts accommodation module is allowed to rotate with an axis line of the light beam, which is irradiated toward a disc, as a rotational center. The grating adjustment mechanism has a cam plane () abut to an abut plane () formed at a portion apart from the axis line and including a slide cam member () mounted in such a condition that said slide cam member is regulated to be movable on a straight line with respect to said carriage body.
