A laser driving device includes a storage unit that stores signal patterns for recording-waveform control representing level information of each divided driving signal to drive a laser device on a space and a mark based on the divided driving signals. Also, it includes a pulse generator that generates the reference pulse and the switching pulse based on a first transmission signal and a second transmission signal. The first transmission signal contains timing information for acquiring a reference pulse that represents a timing of repetitively switching between the space and the mark. The second transmission signal contains timing information for acquiring a switch pulse that represents a timing of switching the signals. Among level information for each of the signals in the storage, reference level information is read together with the reference pulse. Other level information after the reference level information is sequentially read for each switching pulse.
