OPTICAL RECORDING MEDIUM WHERE WOBBLE ADDRESS IS RECORDED

摘要

PURPOSE: An optical recording medium where a wobble address is recorded is provided to realize stable decoding although a system is not capable of recognizing a part of a second MSK(Minimum Shift Keying) mark, thereby improving the stability of the system. CONSTITUTION: Data type identifier marks for identifying data pattern types of address data are recorded at data pattern types respectively, not overlapped with each other between data pattern types. The data pattern includes a pattern identifier mark for identifying a pattern. An interval between the pattern identifier mark and the data type identifier mark in a first data pattern type is different from an interval between the pattern identifier mark and the data type identifier mark in a second data pattern type more than three times as large as a wobble recording nominal unit.
