    • This invention provides an information processing system for a secondary storage medium which can prevent illegitimate reproduction of secondary storage media such as CD-ROMs by allowing only a secondary storage medium in a prescribed relation with a case therefor to be used. A first name data is stored in a secondary storage medium such as a CD-ROM beforehand, while a second name data with a relation with the first name data of the secondary storage medium as well as a name address therefor are stored in a ROM provided in a storage case. When a CPU is activated, it reads the first name data of the secondary storage medium according to the name address and a security element provided in the case compares the first name data with the second name data stored in the ROM. If the security element decides that the two name data have a prescribed relation with each other, a system controller reads a part of the program data stored in the CD-ROM for the inherent object for the image processor and sends it to a main RAM. Then, the CPU runs the program in the main RAM.
    • 本发明提供了一种用于辅助存储介质的信息处理系统,其可以通过仅允许使用具有规定关系的二次存储介质来防止诸如CD-ROM之类的二次存储介质的非法再现。 预先将名称数据存储在诸如CD-ROM的辅助存储介质中,而具有与次要存储介质的名字数据的关系的第二名称数据及其名称地址存储在提供的ROM中 在一个存储盒中。 当CPU被激活时,它根据名称地址读取辅助存储介质的名字数据,并且在该情况下提供的安全性元素将存储在ROM中的第一名称数据与第二名称数据进行比较。 如果安全元件确定两个名称数据彼此具有规定的关系,则系统控制器读取存储在CD-ROM中的用于图像处理器的固有对象的程序数据的一部分,并将其发送到主RAM。 然后,CPU在主RAM中运行程序。
