    • A method of preventing a fraudulent use of an optical disk having a read-write region and a read-only region, comprising the steps of: writing data for designating the boundary between the read-write region and the read-only region into a predetermined block of the optical disk; reading the data out of the predetermined block prior to the execution of the software recorded on an optical disk as an object of fraudulent use check; reading data out of a block which is assumed to be in the read-only region by reference to the data read out of the predetermined block, and writing the data read out of the block in the assumed read-only region into the same block; reading data out of a block which is assumed to be in the read-write region by reference to the data read out of the predetermined block, and writing the data read out of the block in the assumed read-write region into the same block; and judging that the optical disk as an object of fraudulent use check is not a fraudulent copy when the data writing operation is impossible in the block in the assumed read-only region but possible in the block in the assumed read-write region.
    • 一种防止具有读写区域和只读区域的光盘的欺诈性使用的方法,包括以下步骤:将用于指定读写区域和只读区域之间的边界的数据写入预定的 光盘块; 在执行被记录在光盘上的软件作为欺诈性使用检查对象之前,从预定块读出数据; 通过参考从预定块读出的数据,将假定在只读区域中的块读出数据,并将从块中读出的数据写入到相同的块中; 通过参照从预定块读出的数据读出假设在读写区域中的块的数据,并将从块读出的数据写入到相同的块中; 并且当在假设的只读区域中的块中的数据写入操作是不可能的,并且在假设的读写区域中的块中可能时,判断作为欺诈使用检查对象的光盘不是欺诈拷贝。

    • An access control method for drive units that can recognize drive units in specific groups, and drive units to which the method applies are disclosed. The method includes the steps of generating a device driver start request by a driver control program when the OS starts; sending a check command on the basis of the device driver start request; loading the specific device driver corresponding to the specific code contained in the response from the drive unit for the check command; and converting a predetermined host command by the specific device driver and sending the corresponding command to the drive unit under the specific device driver when the predetermined host command for the drive unit under the specific device driver is sent from the host device.

    • An information storage system which can be used by only those users who are previously permitted to access the system is provided. The information storage system has a first information storage device for accessing a first removable recording medium and a second information storage device for accessing a second removable recording medium. An access controller controls access to the first removable recording medium by the first information storage device based on a result of access to the second removable recording medium by the second information storage device prior to access to the first removable recording medium by the first information storage device.

    • A method of preventing unauthorized use includes defining a first original medium ID information stored in a predetermined order which indicates a location of the defect area of an original recording medium, when a block of data to be stored in a defect area of recording media is to be read in a system which has an alternative control for reading a block of data from an alternate area instead of the defect area without accessing the defect area. The method also includes defining a second original medium ID information as a part of data which is stored in the original recording medium and which is to be prevented against unauthorized use, reading out the first original medium ID information from the predetermined address of a recording medium to be judged for unauthorized use and reading out the second original medium ID information as a part of data from the recording medium to be judged. The final step includes judging unauthorized use of data based on the read out first original medium ID information and the read out second original medium ID information.
    • 防止未经授权使用的方法包括:当要存储在记录介质的缺陷区域中的数据块为对象时,定义以指定原始记录介质的缺陷区域的位置的预定顺序存储的第一原始介质ID信息 在具有用于从替代区域而不是缺陷区域读取数据块的替代控制的系统中读取,而不访问缺陷区域。 该方法还包括将第二原始介质ID信息定义为存储在原始记录介质中的数据的一部分并且防止未经授权的使用,从记录介质的预定地址读出第一原始介质ID信息 被判断为未经授权的使用,并从作为要判断的记录介质的数据的一部分读出第二原始介质ID信息。 最后的步骤包括基于读出的第一原始介质ID信息和读出的第二原始介质ID信息判断未经授权的使用数据。
