摘要： An optical system for an optical disk, comprising a light source (61), a collimating optical system (63) for converting a luminous flux from the light source into parallel rays of light, and an object lens (66) for condensing the parallel rays onto the information recording surface (71) of an optical disk. The object lens consisting of two or three lenses and having a numerical aperture (NA) of at least 0.82 enables a high-density recording. Since a third-order astigmatism produced when the object lens is tilted 0.7 degree with respect to an optical axis is as small as up to 10 mnull, a residual aberration, after a third-order comatic aberration produced when the optical disk is tilted due to warping or the like is corrected by tilting the optical lens, can be reduced. Therefore, a tilted optical disk still can ensure a satisfactory recording and/or reproducing quality.
摘要翻译：一种用于光盘的光学系统，包括光源（61），用于将来自光源的光通量转换为平行光线的准直光学系统（63）和用于将平行光线到光盘的信息记录表面（71）上。由两个或三个透镜组成的具有至少0.82的数值孔径（NA）的物镜能够进行高密度记录。由于当物镜相对于光轴倾斜0.7度时产生的三阶散光小至多达10毫巴，所以当由于光盘倾斜而产生三阶彗差之后的残余像差翘曲等通过倾斜光学镜片来校正，可以减少。因此，倾斜的光盘仍然可以确保令人满意的记录和/或再现质量。
