    • A direct current motor driving device for driving a direct current motor (2) having a plus terminal and a minus terminal, which comprises a direct current source (4) having a plus terminal and a minus terminal, the plus terminal being connected to the plus terminal of the direct current motor (2), pulse generating means (12) for generating a pulse signal when an input signal to an input terminal of the pulse generating means (12) exceeds a set threshold value, driving means (14) for driving the direct current motor (2) in response to the pulse signal outputted by the pulse generating means (12), and a first resistance type voltage dividing circuit (16) inserted between the minus terminal of the direct current source (4) and a minus terminal of the direct current motor (2) for providing as the input signal to the pulse generating means (12) a voltage signal produced by resistance-dividing a voltage between these terminals in a first ratio; whereby when a counter electromotive force generated by the direct current motor (2) by the rotation of the direct current motor (2)by an external force in a direction opposite to its driving rotational direction is added to a source voltage of the direct current source (4) to be supplied to the first resistance type voltage dividing means (16), the voltage signal of the first resistance type voltage dividing means (16) is increased to exceed the set threshold value of the pulse generating means (12), and the pulse signal is generated by the pulse generating means (12) to actuate the direct current motor (2). The direct current motor driving device enables direct current motors for general purposes to be actuated and stopped without the use of power switches.

    • A CD-ROM (10) comprises an identifier region (16a) having a disk identifier recorded therein and a security code region (16b) having a security code recorded therein. The identifier region and the security code region are provided in one sector of a boot sector (16) to be read when actuated. The disk identifier includes a preset identification code, and the security code includes at least a program to be executed after check of the security code, and display data for displaying a licence.
      A security check method for a CD-ROM comprising the steps of reading data recorded in the boot sector of the CD-ROM when actuated, comparing the disk identifier read from the identifier region of the boot sector with an stored identifier to check whether or not the read disk identifier is correct, comparing the security code read from the security region of the boot sector with a stored security code to check whether or not the read security code is correct, and executing the program contained in the security code when the read disk identifier and the read security code are correct, and displaying a licence based on the display data.
    • CD-ROM(10)包括其中记录有盘标识符的标识符区域(16a)和其中记录有安全码的安全码区域(16b)。 标识符区域和安全码区域被提供在引导扇区(16)的一个扇区中,以在被致动时被读取。 磁盘识别符包括预先设定的识别代码,安全代码至少包括在检查安全码之后执行的程序,以及显示用于显示许可证的数据。 一种用于CD-ROM的安全检查方法,包括以下步骤:当被驱动时读取记录在CD-ROM的引导扇区中的数据,将从引导扇区的标识符区域读取的盘标识符与存储的标识符进行比较,以检查是否 读取的磁盘标识符是正确的,将从引导扇区的安全区域读取的安全代码与存储的安全代码进行比较,以检查读取的安全代码是否正确,并且当读取的磁盘执行包含在安全代码中的程序时 标识符和读取的安全码是正确的,并且基于显示数据显示许可证。
