Method for recording address information on optical recording medium, optical recording medium including address information recorded thereon by the same method, and method for detecting address information recorded on the same optical recording medium

A device for detecting address information recorded on an optical recording medium, the device comprising:

• a synchronous signal detecting unit detecting synchronous codes from the wobble signal read from the optical recording medium including a wobble-shaped recording track that is formed thereon based on a wobble signal obtained by modulation of physical address information encoded for insertion as a synchronous code in a head of each sector in an error correction code block unit including a predetermined number of sectors, so as to detect sector-by-sector address information of the error correction code block wherein the error correction code block includes N sectors, and the synchronous code of its first sector has a code value different from synchronous codes of the remaining (N−1) sectors, wherein the synchronous signal detecting means detects a synchronous code indicating the first sector in the error correction code block and (N−1) of the same synchronous codes respectively indicating the remaining sectors other than the first sector, from the wobble signal read from the optical recording medium, and outputs, as a synchronous code, a count value obtained by counting the (N−1) synchronous codes on the basis of the detected synchronous code indicating the head of the first sector and the sector address decodes the count value to output sector-by-sector address information;
• an address information detecting unit detecting sector-by-sector address information of the optical recording medium by decoding the detected synchronous code and detecting address information of the error correction code block by decoding remaining portions of the wobble signal other than the synchronous code;
• and
• an address composition unit outputting the physical address of the optical recording medium by combining the detected sector-by-sector address information with the detected address information of the error correction code block.
