    • A compact disk read-only-memory (CD-ROM) data handling system for reading data from a CD by employing a CD drive which is controlled by a computer through an CD-interface to operate at several reading speeds. The CD-ROM data handling system includes a read-error management program executed by the computer for managing a read error. The read-error management program issuing a speed control command through the CD-interface for reducing the CD drive to a lower speed for reading the CD-ROM again at a lower speed whereby the read error is more likely to be prevented. In a preferred embodiment, the read-error management program is provided to automatically issue the speed control command to reduce the CD drive to a lower speed when a read-error occurs. In an alternate preferred embodiment, the read-error management program is provided to receive a user input for issuing the speed control command to reduce the CD drive to a lower speed when a read-error occurs.
    • 一种用于通过采用CD驱动器从CD读取数据的光盘只读存储器(CD-ROM)数据处理系统,该CD驱动器由计算机通过CD接口控制以在几个读取速度下操作。 CD-ROM数据处理系统包括由计算机执行的用于管理读错误的读错误管理程序。 读出错误管理程序通过CD接口发出速度控制命令,用于将CD驱动器降低到较低的速度,以较低的速度再次读取CD-ROM,从而更可能防止读取错误。 在优选实施例中,提供读错误管理程序以在发生读错误时自动发出速度控制命令以将CD驱动器减小到较低速度。 在替代的优选实施例中,读错误管理程序被提供用于接收用于发出速度控制命令的用户输入,以便当读错误发生时将CD驱动器减小到更低的速度。
