摘要： 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.

摘要： A CD-ROM stores encrypted software. When a user desires to decrypt and install this software, an approval preparatory key is generated by an installer. This approval preparatory key is generated based on time data. When the user informs a center of this approval preparatory key, the center calculates a difference between this approval preparatory key and a decrypting key and vends this calculated result to a user in the form of an approval key. When the user inputs this approval key to an installer, the installer generates a decrypting key by adding the approval preparatory key to the approval key. The installer decrypts the software by this decrypting key and installs the encrypted software into a personal computer system.
摘要翻译： CD-ROM存储加密软件。当用户希望解密并安装此软件时，安装程序会生成一个批准预备密钥。此批准预备密钥是基于时间数据生成的。当用户向中心通知该批准预备密钥时，中心计算该批准预备密钥和解密密钥之间的差异，并以批准密钥的形式将该计算结果交给用户。当用户向安装者输入该批准密钥时，安装者通过将批准预备密钥添加到批准密钥来生成解密密钥。安装人员通过该解密密钥解密软件，并将加密的软件安装到个人计算机系统中。

摘要： Common-use data (FATs, a directory, files, etc.) is recorded in a first area of an interchangeable recording medium, and logical format information of a plurality of types for managing the common-use data recorded in the first area is recorded in the second area. When the interchangeable recording medium is loaded, a computer reads logical format information conforming to its own machine type from the second area and subsequently accesses the common-use data in the first area based upon the logical format information read. Further, a corresponding relationship between computers and storage locations of the logical format information is recorded in a third area of the interchangeable recording medium. Each computer recognizes the location, at which its own logical format information has been stored, by referring to the corresponding relationship and reads the logical format information from this location. The computer subsequently accesses the common-use data in the first area based upon the logical format information read.

摘要： A vendor ID is written to a system area of a write-once optical disk. When the write-once optical disk is loaded onto a write-once disk drive, a control CPU reads the vendor ID. The vendor ID is written into the header of software received through an interface unit. When the software is input to an SD circuit, the control CPU reads the vendor ID. The control CPU compares the vendor ID in the system area of the write-once optical disk with the vendor ID of the header of the software and checks whether or not the two IDs are identical. If the two IDs correspond to each other, the control CPU writes the software to the write-once optical disk.

摘要： An optical disk is divided into a plurality of sections at least one of which (a first section) is made a section (formatted in MS-DOS, for example) having a format different from the logical format of a CD-ROM. Publication data is optically recorded in at least one section (a second section) of the sections other than the first section in accordance with the CD-ROM logical format. A CD-ROM utilization tool that utilizes publication data in the CD-ROM logical format and a CD-ROM emulator for converting a request for access to the CD-ROM logical section issued by the CD-ROM utilization tool to a request for access to the optical disk are recorded in the first section.
摘要翻译：光盘被分成多个部分，其中至少一个（第一部分）被制成具有不同于CD-ROM的逻辑格式的格式的部分（例如在MS-DOS中格式化）。根据CD-ROM逻辑格式，公开数据被光学地记录在除了第一部分之外的部分的至少一个部分（第二部分）中。一种使用CD-ROM逻辑格式的发行数据的CD-ROM利用工具和用于将由CD-ROM利用工具发布的CD-ROM逻辑部分的访问请求转换为访问请求的CD-ROM仿真器光盘被记录在第一部分中。
