    • Provided are a method and apparatus for recording and/or reproducing data into and/or from an optical disk. The apparatus includes a reference beam optical system to form a focus of a reference beam in an optical data storage layer of the optical disk and including an objective lens; a signal beam optical system to form a focus of a signal beam in the optical data storage layer and also including the objective lens; and a servo optical system to project a servo beam onto the optical disk, receiving a reflection servo beam which is reflected on the optical disk, and performing focusing and tracking control on the objective lens. The reference beam optical system includes a first focus mover to move the focus of the reference beam, and the signal beam optical system includes a second focus mover to move the focus of the signal beam. The data is recorded into a plurality of recording layers in the optical data storage layer by moving a first focus position, at which the foci of the reference beam and the signal beam are located, in a thickness direction of the optical data storage layer, which is a focusing direction.
    • 提供了一种用于在光盘中记录和/或再现数据的方法和装置。 该装置包括:参考光束光学系统,用于在光盘的光学数据存储层中形成参考光束的焦点,并包括物镜; 信号光束光学系统,用于在光学数据存储层中形成信号束的焦点,并且还包括物镜; 以及将伺服光束投射到光盘上的伺服光学系统,接收在光盘上反射的反射伺服光束,并对物镜进行聚焦和跟踪控制。 参考光束光学系统包括用于移动参考光束的焦点的第一聚焦移动器,并且信号光束光学系统包括第二聚焦移动器以移动信号光束的焦点。 通过在光学数据存储层的厚度方向上移动参考光束和信号光束所在的第一焦点位置,将数据记录在光学数据存储层中的多个记录层中, 是聚焦方向。
