<p>PROBLEM TO BE SOLVED: To reduce temporal fluctuation of a clock period.SOLUTION: A clock generation part generates a reproduction clock for reproducing a medium, a phase shift part displaces a phase of the reproduction clock by phase displacement distributed at an equal interval over one period, an addition part calculates a total value by counting the phase-displaced reproduction clock, and a control part controls a clock period of the reproduction clock generated by the clock generation part so that a difference between a total value expressed by data received by a receiving part and the total value calculated by the addition part is minimized.</p> |
