    • A method and apparatus for identifying an optical information storage medium, the method of identifying the optical information storage medium loaded into an apparatus for reproducing/recording the optical information storage medium including: moving an object lens at a predetermined velocity in a first direction or a second direction while the optical information storage medium is loaded; generating a sum signal by adding magnitudes of beams reflected by the optical information storage medium and condensed by an optical detector; measuring a first time period during which the sum signal has a value greater than a first level; and detecting a thickness of data layers of the optical information storage medium based on the first time period, wherein the thickness of the data layers corresponds to the type of the optical information storage medium.
    • 一种用于识别光学信息存储介质的方法和装置,识别装载到用于再现/记录光学信息存储介质的设备中的光学信息存储介质的方法,包括:以预定速度沿第一方向移动物镜或 第二方向,同时加载光学信息存储介质; 通过将由光信息存储介质反射的光束的大小相加并由光检测器进行会聚来产生和信号; 测量所述和信号具有大于第一电平的值的第一时间段; 以及基于所述第一时间段检测所述光学信息存储介质的数据层的厚度,其中所述数据层的厚度对应于所述光学信息存储介质的类型。
