Abstract:
A recording apparatus, comprising:laser means for performing laser beam irradiation with a supplied driving pulse to form a recording data row on a recording medium, said data row being formed of pits and lands, the lands being between the pits and the pits being before and after the lands; driving pulse generating means for generating a first pulse in accordance with recording data, a second pulse to be combined with a leading edge portion of the first pulse, and a third pulse to be combined with a trailing edge portion of the first pulse, and for synthesizing the driving pulse by combining the first, second, and third pulses; and pulse generation control means for controlling at least one of the first, second, and third pulses generated by said driving pulse generating means so that one of a level and a pulse width thereof is varied in accordance with a length of at least one of a pit and a land to be formed, wherein said pulse generation control means controls at least one of the first, second, and third pulses so that one of the level and pulse width thereof is varied in accordance with a speed at which said recording data row is formed on the recording medium.
