OPTICAL DISK RECORDING DEVICE

PROBLEM TO BE SOLVED: To provide an optical disk recording device in which transfer speed of modulation data from a main board to a pickup and reliability are improved. SOLUTION: The optical disk recording device having the main board 112 and the pickup 113 is provided with a clock recovery circuit 102 generating a recording clock 108 from modulation data 107 transferred to the pickup 113 from the main board 112, and a write-strategy 103 generating recording timing 109 from the modulation data 107 and the recording clock 108, and skew between modulation data and a frequency divided recording clock is not present any more.
