    • An optical disk reproducing apparatus for reproducing digital signals in the form of a data frame including a lead-in block and data blocks from an optical disk including at least first and second recording surfaces each being readable from a same side of the optical disk. The data blocks include block addresses and data, and are recorded on the first and second recording surfaces. The lead-in block is recorded at a head of the data frame and includes disk information relating to a number of data blocks recorded on the first and second recording surfaces. The apparatus includes an optical pickup, a focus control circuit, a pickup movement control circuit, a disk information detection circuit which detects disk information included in a reproduced lead-in block, a block address detection circuit which detects block addresses included in reproduced data blocks, and an access/reproduction control circuit which controls the focus control circuit and the pickup movement control circuit to access the first and second recording surfaces and reproduce data blocks recorded thereon. The access/reproduction control circuit controls the focus control circuit to perform focus changing of the optical pickup to access the first and second recording surfaces in accordance with block addresses of data blocks to be reproduced and the detected disk information.
    • 一种用于再现数字信号的光盘再现装置,该数据信号包括从光盘至少包括第一和第二记录表面的数据块和数据块,每个记录表面可从光盘的同一侧读取。 数据块包括块地址和数据,并被记录在第一和第二记录表面上。 导入块被记录在数据帧的头部,并且包括与记录在第一和第二记录表面上的多个数据块有关的盘信息。 该装置包括光拾取器,聚焦控制电路,拾取移动控制电路,检测包含在再现的导入块中的盘信息的盘信息检测电路,块地址检测电路,其检测再现数据块中包括的块地址 以及访问/再现控制电路,其控制聚焦控制电路和拾取器移动控制电路以访问第一和第二记录表面并再现其上记录的数据块。 访问/再现控制电路控制聚焦控制电路,以根据要再现的数据块的块地址和检测到的盘信息来执行光学拾取器的聚焦改变以访问第一和第二记录表面。
