As shown in FIG. 7. the structure by bi-phase modulation is different from the structure illustrated in FIG. 2. That is, the method of FIG. 2 has a bit with value 0, which is represented by a transition at the start of the bit cell and a bit with value 1, which is represented by a transition at the start and in the middle of the bit cell. Otherwise, the method of FIG. 7 has a bit with value 0, which is represented by a transition at the start of low and in the middle of high, and a bit with value 1, which is represented by the transition in the opposite direction. The combination of bits consists of data to detect information recorded as wobbled pit. The information can be copy protection information, i.e., key data to decrypt main data recorded on the data zone of the recording medium as shown in FIG. 4A to 4F
That is, the wobbled pit data can be reproduced or detected only when the bi-phased modulation data modulated by HFM is detected or reproduced normally. And also, reproduction or decryption of main data is possible only when the wobbled pit data for copy protection is reproduced or detected using the normally detected or reproduced bi-phase modulation data.
