Patent ID: 8228773

Claim:
A laser driving device, comprising: a storage unit for storing signal patterns for recording-waveform control representing level information of each of plural divided driving signals to drive a laser device on a space and a mark on the basis of said plural divided driving signals; and a pulse generator for generating a reference pulse and a switch pulse on the basis of a first transmission signal containing information for defining a timing of acquiring said reference pulse that represents a timing of repetitively switching between said space and said mark and a second transmission signal containing information for defining a timing of acquiring said switch pulse that represents a timing of switching divided driving signals, wherein, among level information for each of said divided driving signals stored in said storage, reference level information which is level information about the position of said reference pulse is read together with said reference pulse, said switch pulse is one of a plurality of switch pulses, and other level information subsequent to the reference level information is read out one by one for each of said plurality of switch pulses.
