Abstract

An optical pick-up head includes a light source, a collimator lens, a polarizing beam splitter (PBS), at least one focusing lens, an optical compensator, a spherical aberration corrector and a light detector. The light source emits a light beam. The collimator lens collimates the light beam. The PBS splits the light beam with respect to the polarizing direction. The focusing lens focuses the light beam on a focus. The optical compensator is disposed between the focus and the PBS and includes two first inclined objects. The thickness of the optical compensator is changeable by the mutual movement of the first inclined objects. The spherical aberration corrector is disposed between the focus and the focusing lens and includes two second inclined objects. The thickness of the spherical aberration corrector is changeable by the mutual movement of the second inclined objects. The photo delector detects the light beam passing through the PBS.
