摘要： To provide an optical disk device, an optical disk control method and an integrated circuit, which are capable of writing a recordable mark by changing the reflectance ratio of a reflective film formed on concave-convex pits without using an industrial special device or a high-power laser light source. A data reproduction controller (103) sets a first rotation speed in a disk rotation speed switching unit (108) and a first laser power in a laser power switching unit (107) when reproducing the concave-convex pits. When writing the recordable mark, a mark recording controller (104) sets in the disk rotation speed switching unit (108) a second rotation speed that is slower than the first rotation speed and the lowest rotation speed at which the concave-convex pits can be reproduced, and sets a second laser power greater than the first laser power in the laser power switching unit (107) in accordance with the emission timing.

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.

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.

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.
