    • An optical disc drive and a method of reading an optical disc are disclosed. The drive includes an I/O port, an optical pickup module and a format conversion unit. The I/O port couples a host to receive a read command of a host terminal file system format. The optical pickup module accesses the optical disc which contains data of a first file system format. The format conversion unit coupled between the I/O port and the optical pickup module includes a mapping information generation module, a memory module and a read-command processing module. The mapping information generation module controls the optical pickup module to access data and thereby to generate mapping information. The memory module stores the mapping information. The read-command processing module controls the optical pickup module to access the optical disc according to the read command by referring to the mapping information.
    • 公开了一种光盘驱动器和一种读取光盘的方法。 驱动器包括I / O端口,光学拾取模块和格式转换单元。 I / O端口将主机连接以接收主机终端文件系统格式的读取命令。 光学拾取模块访问包含第一文件系统格式的数据的光盘。 耦合在I / O端口和光学拾取模块之间的格式转换单元包括映射信息生成模块,存储器模块和读取命令处理模块。 映射信息生成模块控制光学拾取模块访问数据,从而生成映射信息。 存储器模块存储映射信息。 读取命令处理模块通过参考映射信息来控制光学拾取模块根据读取命令访问光盘。
