<P>PROBLEM TO BE SOLVED: To solve the problem, i.e., if data is recorded using a disk with deviating characteristics and a recorder with deviating characteristics, data is not appropriately recorded, and errors occur in the read signal. <P>SOLUTION: Standard recording pulse conditions specifying recording pulse positions for plural possible mark length and space length combinations are read from a writable optical disk. These standard recording pulse conditions are used for test writing. The standard pulse conditions are changed uniformly or individually, and a best recording pulse condition is obtained, thereby reducing jitter. <P>COPYRIGHT: (C)2009,JPO&INPIT |
