摘要： A digital work (102) and copyright management information (103) for the digital work are recorded on an information recording medium (101) by altering a shape, a position or a pattern (104, 105) of recording mark edges of the digital work. Alternatively, a decryption key for the right management information is recorded on an information recording medium on which the copyright management information has been recorded encrypted, by altering the recording mark edges of the copyright management information. Alternatively, a check code for the copyright management information is recorded on the information recording medium by altering the recording mark edges. The check code is checked when the copyright management information is read, thus detecting illegal use of the copyright management information.

摘要： An optical disk is provided that disables reproduction of sub-information even if the sub-information as a contents encryption key is recorded entirely onto another optical disk. Sub-information is recorded on the optical disk by deforming a recording mark slightly in accordance with a pseudo random number sequence that is obtained using as an initial value medium ID that is read out medium inherent information. This allows sub-information inherent in a medium to be recorded, and even if the sub-information is duplicated entirely to another optical disk, the illegally duplicated sub-information cannot be reproduced because of a difference in initial value of a pseudo random number sequence between media.

摘要： An information recording medium for recording main information and auxiliary information is provided. The auxiliary information is recorded on the information recording medium in a manner that edge positions of the pits or the recording marks indicating the main information are shifted either in a phase advancing direction or in a phase delaying direction along the track direction. A predetermined frequency is used to determine whether the edge position is shifted in the phase advancing direction or in the phase delaying direction in order to record the auxiliary information. The predetermined frequency is substantially consistently lower than ½ of a reference frequency of a recording clock for creating the pits or the recording marks and is higher than a response frequency of a PLL for generating a reproduction clock for reproducing the main information.

摘要翻译： 提供用于记录主信息和辅助信息的信息记录介质。 辅助信息被记录在信息记录介质上，使得指示主信息的凹坑或记录标记的边缘位置沿着轨道方向在相位前进方向或相位延迟方向上偏移。 为了记录辅助信息，使用预定频率来确定边缘位置是否在相位前进方向或相位延迟方向上偏移。 预定频率基本上始终低于用于产生凹坑或记录标记的记录时钟的参考频率的1/2，并且高于用于产生用于再现主信息的再现时钟的PLL的响应频率。

摘要： An optical storage medium can be provided by which illegal usage of the optical storage medium involving an infringement on the copyright can be prevented effectively without impairment of the functions for reproducing physical format information and optical storage medium manufacturing information. The optical storage medium includes a main information region in which encrypted data information is recorded as a pit row that is capable of being read out by means of light and a control data region. In the control data region, key information for decoding the encryption of the data information, the physical format information and the optical storage medium manufacturing information are recorded by wobbling a groove.
