<P>PROBLEM TO BE SOLVED: To perform high quality recording by effectively compensating the influence by intrinsic characteristic of a semiconductor laser or the like, a characteristic of a driving circuit, and the characteristic of the combination of the above. <P>SOLUTION: In a recording unit of an information recording device performing information recording for an optical disk or the like, recording waveform data prescribing a drive pulse supplied to a recording light source such as a laser diode is provided as digital data. In this digital data, a intrinsic characteristic caused by a used laser diode, a laser driver, and the combination of them are considered, and this digital data is made so that a suitable laser outgoing waveform is obtained when the laser diode and the laser driver are used, and previously stored. At the time of recording actual information, digital data previously provided is read out in accordance with the data to be recorded, recording power, or the like, and a drive pulse waveform is generated, this data is converted into an analog signal and the laser diode is driven, Thereby, the influence by an intrinsic character of the laser diode or the like is eliminated, and appropriate information recording can be performed. <P>COPYRIGHT: (C)2004,JPO |
