发明名称 Optical pickup head
摘要 <p>In an optical pickup head, a light source emits a light beam. A first reflecting section reflects the light beam emitted from the light source and changes a direction of a travel of the light beam emitted from the light source. A second reflecting section reflects the light beam and changes a direction of a travel of the light beam after the light beam is reflected by the first reflecting section. The light beam reflected by the second reflecting section is focused on the optical recording medium. The light beam is reflected and diffracted by the optical recording medium. The light beam reflected and diffracted by the optical recording medium is detected. A common support member is formed with both the first and second reflecting sections. <IMAGE></p>
