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： 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 disc recording apparatus (10) is provided with a tracking servo (13) for tracking a spiral track of concave and convex marks, an analog signal processor (14) for extracting a reproduction signal corresponding to the concave and convex marks, a digital signal processor (15) for extracting a channel clock synchronized with a channel bit length of the concave and convex marks, and a sub-information recording section (30) for recording sub-information by irradiating laser light based on the tracking to the spiral track. The sub-information recording section (30) records all the sub-information by repeating a process of recording a part of the sub-information by discretely irradiating laser light at a specified interval and with a specified frequency in synchronism with a channel clock by one tracking to form recordable marks on a reflective film a plurality of times. By this construction, a tracking control to the concave and convex marks can be stably executed and the sub-information can be stably recorded.

摘要： On an optical disc, main information to be decrypted using sub information is recorded by arranging concave or convex recording marks in a spiral track and a reflective film is formed on the recording marks. First sub information is recorded as being superimposed on the main information by shifting or deforming the recording marks or altering a pattern of the recording marks. Second sub information is recorded as being superimposed on the main information by changing a reflectivity of the reflective film formed on the recording marks. The first sub information and the second sub information are recorded in an area from which the first sub information and the second sub information are to be read simultaneously. The second sub information is recorded in a manner that the second sub information is associated with the first sub information. The first sub information and the second sub information are associated with each other, and improve resistance to unauthorized copying by prohibiting content information from being read unless both the first sub information and the second sub information are read. The first sub information and the second sub information are recorded in the same area, and prevent the time taken for reading sub information from increasing.
