摘要： If information is to be recorded on and reproduced from a recording medium in correspondence between a code train in the form of a run-length-limited code and the positions of the leading edge and the trailing edge data of a status transition pattern such as pits, recording domains, a sync signal is inserted at regular intervals in the information converted in the form of the run-length-limited code. The sync signal is constituted by a code train capable of deciding that the sync signal includes a code not existing in the conversion rule into a run-length-limited code during reproduction using a leading edge data or trailing edge data relative to the transition pattern.

摘要： The disk recording apparatus and method are arranged to specify a recording address and a recording position on an optical disk with a wobble PM (phase modulation) format through the use of a wobble reproduced signal and a track reproduced signal. The recording apparatus operates to detect address information and a synchronous signal on the optical disk that correspond with the wobble reproduced signal and the track reproduced signal sent from the optical disk respectively. Then, the address information required for specifying a disk recording track and the synchronizing timing required for specifying a linking position are selected from the detected states.

摘要： For protecting the recording from shifting in the position, by conducting sync detection, correctly, from land pre pits, in an optical type recording disc, even if sync pattern errors, in more detail, synchronization is conducted on a recording circuit, with certainty, even if an even sync pattern erroneously changes into an odd sync pattern. When the even sync pattern is detected from an odd sync pattern detection window, a sync lock flag is turned into a condition of unlock. When the sync lock flag continues a lock condition for 16 sectors, the synchronization is carried out on a detection cycle counter and a recording cycle counter.
