Abstract
A pickup device has a light source, an objective lens for converging rays of light emitted from a light source onto a recording medium, a lens holder for holding the objective lens, and supporting element for movably supporting the lens holder. The pickup device is uniquely featured in that a part of the objective lens and a part of the lens holder are movable relative to each other so as to adjust an inclination of an optical axis of the objective lens.
