INFORMATION RECORDING DEVICE AND METHOD, AND COMPUTER PROGRAM

摘要

An information recording device (2), which irradiates laser light to a recording medium and forms a recording mark corresponding to a recording signal, is provided with a light source (21) for projecting the laser light and a signal generating means (22) for generating a recording pulse signal which drives the light source in accordance with the recording signal, wherein the recording pulse signal includes mark and space periods and the recording pulse signal is such a level of the mark period corresponding to a long mark that a waveform distortion corresponds to recording power that is not less than the upper limit (L) or not more than the lower limit (-L) of the amplitude limit values in a limit equalizer (15).
