Filed: 2001-09-20
Abstract: PROBLEM TO BE SOLVED: To prevent incorrect selection of optimum recording power, as to OPC by which recording power is variously changed to perform trial writing and the recording power is optimized in a PC area of an optical disk. SOLUTION: An RF signal processing part 20 calculates a jitter value from test data recorded on the PCA area of the optical disk 10, and supplies it to a control part 24.
