Abstract

PURPOSE: To reduce spread of heat due to temperature rise of a part forming a recording pit on a recording medium in forming a long recording pit by using a generated pulse train having different peak value so as to drive a laser thereby recording a signal.
CONSTITUTION: A gate signal generating circuit 11 generating a gate signal in response to a level inverting interval and a recording pulse circuit 12 generating a pulse train having different peak value in response to a gate signal are provided. A pulse train as a waveform 53 is outputted from the recording pulse generating circuit 12, a laser drive circuit 13 modulates the stimulated power of the laser 14 according to the pulse train to irradiate the laser light on a recording medium 15. Since the power change in the laser light changes according to the waveform 53, the width of the recording pit is not spread even when the sector of the H level of the recording signal is long.
