    • The optical head device disclosed has a light source, a super-resolution filter, an objective lens system a data recording medium, a reconverging lens system, and a photo-detecting system including a photodetector. The super-resolution filter provides a predetermined light intensity distribution with respect to the laser light emitted from the light source. When the data recording medium is a light reflection type, the objective lens system is both for converging the light on the data recording medium and for collecting the light reflected therefrom and, when the same is a light transmission type, the objective lens system comprises a light converging lens for converging the light on the data recording medium and a light collecting lens for collecting the light transmitted through the data recording medium. The objective lens system has a numerical aperture larger for the light collecting than that for the light converging. The re-converging lens system is for converging the light from the data recording medium, and the photodetector is for detecting a center portion of a flux of the light reconverged by the reconverging lens system. Even when the data recording density becomes high, the deterioration of the reproduced signal can be greatly reduced.
    • 所公开的光头装置具有光源,超分辨率滤光器,物镜系统,数据记录介质,再融合透镜系统和包括光电检测器的光检测系统。 超分辨率滤光器相对于从光源发射的激光提供预定的光强度分布。 当数据记录介质是光反射型时,物镜系统既用于将光会聚在数据记录介质上并用于收集从其反射的光,并且当它们是透光型时,物镜系统包括 用于将光会聚在数据记录介质上的聚光透镜和用于收集透过数据记录介质的光的聚光透镜。 物镜系统具有比聚光更大的数值孔径。 再会聚透镜系统用于会聚来自数据记录介质的光,并且光电检测器用于检测由再融合透镜系统再次恢复的光的通量的中心部分。 即使当数据记录密度变高时,再现信号的劣化也可以大大降低。
