Abstract(in English) | DVD/CD compatible optical system which has few cost consuming restriction such as aperture restriction and/or changing magnification for CD reproduction was developed. The objective lens is designed to satisfy the spot profile performance for both media. In case of 2 laser optical system for CD-R reproduction, additional photo diode is not necessary. Tolerance of designed objective was calculated and was compared to conventional objective for DVD and that of CD. The result shows that tolerance performance of the newly designed objective is similar to that of conventional objectives. Therefore, the objective is applicable to conventional optical system without changing mechanical tolerance. |
