    摘要： To provide a recording medium on which an entire piece of decryption information that is required to be highly secure is recorded while being kept secure even when it is larger in data size than the storage capacity of an area originally intended for recording it. A recording medium in which encrypted content that has been encrypted and decryption information for the decryption of the encrypted content are recorded in two areas of different security levels. Decryption information B which is a portion of the decryption information is recorded in an area L of a relatively higher security level. The encrypted content and decryption information C which is the remainder of the decryption information that has been encrypted are recorded in an area D of a relatively lower security level. The decryption information B recorded in the area L includes information indicating the location where the decryption information C is recorded and information for the decryption of the remainder.

    摘要翻译： 为了提供一种记录介质，在该记录介质上记录需要高度安全的整个解密信息，即使当数据尺寸大于原始用于记录的区域的存储容量时，也能保持安全。 其中已经加密的加密内容和用于解密加密内容的解密信息被记录在不同安全级别的两个区域中的记录介质。 作为解密信息的一部分的解密信息B被记录在相对较高安全级别的区域L中。 作为已被加密的解密信息的其余部分的加密内容和解密信息C被记录在相对较低安全级别的区域D中。 记录在区域L中的解密信息B包括指示解密信息C被记录的位置的信息和用于其余部分的解密的信息。

    摘要： By the method of processing data, the data can be processed, without encrypting and decrypting all of the data, so as to keep secrecy of the data. The method comprises the steps of: storing data of a system area of a recording medium, which are used by the writing means so as to recognize the recording medium; encrypting at least a part of the data of the system area on the basis of a password; storing main data; writing the encrypted data of the system area in the recording medium; and writing the main data in the recording medium.

    摘要翻译： 通过处理数据的方法，可以处理数据，而不对所有数据进行加密和解密，以保持数据的保密性。 该方法包括以下步骤：存储由写入装置使用以记录记录介质的记录介质的系统区域的数据; 基于密码对系统区域的数据的至少一部分进行加密; 存储主数据; 将系统区域的加密数据写入记录介质中; 并将主数据写入记录介质。

    摘要： A recording disc has a lead-in area and a data area. A scrambled version of a SID code word is read out from the lead-in area of the disc. The SID code word represents a producer of the disc. The readout scrambled version is de-scrambled to recover the SID code word. The recovered SID code word is collated with reference SID code words to decide whether or not the disc is legitimate. Main information is read out from the data area of the disc when it is decided that the disc is legitimate. Readout of the main information from the data area of the disc is inhibited when it is decided that the disc is not legitimate.
