摘要： A light scanning system employing a rotating mirror, spherical lens, and a toric-surfaced reflecting mirror. The toric-surfaced reflecting mirror is disposed in the optical path between the spherical lens and the image plane. The spherical lens sufficiently corrects field curvature and the toric-surfaced reflecting mirror corrects scan nonlinearity. And by the spherical lens and the toric-surfaced reflecting mirror together, the field curvature and the scan nonlinearity are satisfactorily corrected. The toric-surfaced reflecting mirror is surfaced to have a circular arc with a larger radius of curvature in the scan plane and to have a circular arc with a smaller radius of curvature in the cross-scan plane.

摘要： When the DVD provided with the DVD substrate 2 having thickness t2 of 0.6 mm is installed in the optical disc apparatus, the light beam 4 having wavelength λ1=655 nm is used as luminous flux of numerical aperture NA=0.63 to be condensed on the information surface 2a on the DVD substrate 2. When the CD provided with the CD substrate 3 having thickness t2 of 1.2 mm is installed in the optical disc apparatus, the light beam 5 having wavelength λ2=790 nm is effectively used as luminous flux of approximate numerical aperture NA=0.45 to be condensed on the information surface 3a on the DVD substrate 3. The wavefront aberration caused by a thickness difference between the DVD substrate 2 and CD substrate 3 is canceled out by the chromatic aberration caused by a wavelength difference between the light beams 4 and 5. Therefore, in spite of the difference in the transparent substrates, the light beams are suitably condensed respectively on the information surface 2a and 3a.
摘要翻译：当设置有厚度为0.2mm的DVD基板2的DVD被安装在光盘装置中时，波长λ1 = 655nm的光束4是用作数值孔径NA = 0.63的光通量在DVD基板2上的信息表面2a上聚光。当光盘装置中安装有厚度为2nm×1.2mm的CD基板3的CD时，波长λ2 = 790nm的光束5为有效地用作近似数值孔径NA = 0.45的光通量在DVD基板3上的信息表面3a上聚焦。由DVD基板2和CD基板3之间的厚度差引起的波前像差由于光束4,5之间的波长差造成的色差而抵消。因此，尽管透明基板的差异，光束分别适当地冷凝在信息表面2a和3a上。
