PROBLEM TO BE SOLVED: To provide an optical disk drive which can stably reproduce a recorded disk after linking by stably supplying a recording clock at a linking point when additionally writing data by linking operation in a write-once or rewritable optical disk such as DVD-R/RW. SOLUTION: The optical disk drive 1 is equipped with a PLL circuit 21 for recording and a controller 19. The PLL circuit 21 for recording generates a recording clock, and a controller 19 controls a loop gain value of the PLL circuit 21 for recording. To be more precise, the controller 19 changes the loop gain value from the first gain value to the second gain value before linking point of data, and holds the second gain value on the linking point of the data.
