ピックアップにおいて、前記反射部材の反射面は、前記
発光素子からの入射光を平行光にする形状に凹彎曲形成
されていることを特徴とする光学式ピックアップ。In an optical pickup, a reflective member is provided behind an objective lens facing a recording medium, and a light emitting element is provided on an optical axis that is reflected by the reflective surface of the reflective member and directed toward the objective lens. An optical pickup characterized in that the reflective surface of the member is formed with a concave curve to convert incident light from the light emitting element into parallel light.
