INFORMATION RECORDING MEDIUM, INFORMATION RECORDING DEVICE AND METHOD, INFORMATION REPRODUCING DEVICE AND METHOD, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To achieve the copyright protection for recorded data such as contents and the preservation of reproducing compatibility at the same time, in information recording media such as recording type media. SOLUTION: An optical disc (100) includes a recording region where prescribed clock information (WBL) is preformatted for recording. The clock information is (i) included in a first frequency band that is definable by a first reference frequency (Fstd) (that is impossible for a conventional reproducing device to detect by a detecting method based on a self-correlation) and is (ii) defined by a frequency that is integer times the first frequency.
