摘要: This invention discloses a micro optical pickup apparatus for providing an incident light to an optical recording medium, receiving a reflected light from the optical recording medium, and thereby accessing data of the optical recording medium. The micro optical pickup apparatus includes a light source generating element for producing the incident light, an axial light splitting element allowing the incident light to pass through and deflecting the reflected light according to polarization directions of the incident and reflected lights, a polarization element disposed between the axial light splitting element and the optical recording medium is capable of changing the polarization directions of the incident light and reflected light of the optical recording medium, an astigmatic mirror for receiving, astigmatism focusing and reflecting the reflected light from the axial light splitting element, and an optical sensing element for receiving the reflected light from the astigmatic mirror and converting the reflected light into a corresponding electric signal.
