Summary:PROBLEM TO BE SOLVED: To solve the problem that it is necessary to increase a speed for a light source driving part when high-speed recording is carried out while the mark of a predetermined length cannot be accurately recorded. SOLUTION: When the first set of recording data including a shortest mark length among the recording data of mark lengths and having different mark lengths to be recorded at 2T (T is a recording channel clock cycle) from the shortest mark length are recorded, the pulse width of a rear part cooling pulse and the pulse width of a rear part heating pulse are set equal to the recording channel clock cycle, and the sum total of the pulse widths of the multi-pulse lights is increased twice as large as the recording channel clock cycle T.
