    • A compatible optical pickup including an active compensation device to actively switch an angle of incidence of the light on the objective lens when either a third information storage medium that has a different format than that of the first and second information storage media, or the second information storage medium is adopted for use in a data recording/reproducing operation. The active compensation device includes a plurality of transparent substrates, and at least one material layer, interposed between the plurality of substrates, having a refractive index which is actively switched according to an applied voltage. A holographic pattern, formed adjacent to the material layer on a surface of at least one of the transparent substrates, changes a divergence angle of the light by diffracting or transmitting without diffraction the incident light according to change of the refractive index of the material layer. The voltage applied to the material layer is adjusted according to the applied information storage medium that is adopted for the use in the data recording/reproducing operation.
    • 一种兼容的光学拾取器,包括有源补偿装置,用于当具有与第一和第二信息存储介质的格式不同的格式的第三信息存储介质或第二信息时主动切换光在物镜上的入射角 采用存储介质用于数据记录/再现操作。 有源补偿装置包括多个透明基板,以及介于多个基板之间的至少一个材料层,具有根据施加的电压有效切换的折射率。 根据材料层的折射率的变化,在至少一个透明基板的表面上与材料层相邻形成的全息图案通过衍射或透射衍射或透射而不衍射入射光而改变光的发散角。 根据在数据记录/再现操作中使用的应用信息存储介质来调整施加到材料层的电压。
