摘要： An optical disk, and a method and apparatus for reproducing and/or recording data to the disk are provided for preventing illegal copying of authorized disks recording copyrighted digital content. The optical disk 10 has a control area 12 for storing control data, a data area 14 for storing main digital data (content), and an identification area 13 for storing sub-digital data specific to the main digital data. The sub-digital data is recorded as a pit sequence at a locally phase modulated clock timing. When disk identification data is recorded as the sub-digital data, key information stored to the reproduction apparatus is compared with identification data (sub-digital data) detected from jitter fluctuations in the identification area 13 when content is reproduced from the optical disk 10. If a specific correlation is thus confirmed, the disk is recognized as a legally copied disk and reproduction is enabled. Illegal copies can thus be prevented.

摘要： A method for recognizing at least two types of optical discs, which are associated with multiple different numerical apertures, includes the step of setting the numerical aperture of a focusing mechanism equal to a first one of the multiple different numerical apertures. The focusing mechanism is used to focus a light beam on a data storage layer of a given optical disc. The first numerical aperture is smaller than any of the other numerical apertures. The method further includes the step of recognizing the type of the given optical disc by the first numerical aperture that has been selected in the step of setting the numerical aperture.

摘要： An information medium apparatus for performing at least one of a recording operation and a reproduction operation for the information medium, includes: a determination section for determining whether or not a cartridge for accommodating the information medium has been previously opened; and a control section for performing a start processing procedure corresponding to the information medium. When it is determined that the cartridge has not been previously opened, the control section performs a first start processing procedure for starting the information medium by using a blue laser. When it is determined that the cartridge has been previously opened, the control section determines whether or not the information medium is an information medium for which a start processing procedure is to be performed by using a laser other than the blue laser.

摘要： A method of reproducing an optical disk storing main digital data recorded by optically readable recording marks and sub-digital data, the sub-digital data being superposed with the main digital data and being recorded to the disk by slightly displacing positions or shapes of the recording marks in a track direction of the recording mark, the method comprising constructing a pattern based on the sub-digital data, comparing the pattern with a predetermined key information, and restricting a reproduction of content recorded by the main digital data when a correlation between the pattern and the key information is not confirmed, wherein the reproduction is restricted by dropping the transfer rate to degrade image quality, or by performing intermittent reproduction.
The key information may be obtained via a network.-
