Information recording device

An information recording device, for recording an optical recording medium having a recording layer, where recording information is formed thereon as a mark, by irradiating a laser beam with a light-emission waveform corresponding to a recording pulse, the information recording device comprising:

• a rotation driving mechanism, for rotating the optical recording medium;
• a rotation controlling means, for controlling a rotation operation of the optical recording medium due to the rotation driving mechanism, according to an assigned recording linear velocity;
• a laser light source, for emitting the laser beam;
• a light source driving means, for causing a light emission of the laser light source;
• a recording pulse generating means, capable of generating each rectangular pulse of a single pulse and each multi-pulse with a combination of a leading heating pulse and a succeeding heating pulse, any one of which is as the recording pulse;
• and
• a recording pulse selection means, for switching and selecting the multi-pulse and the rectangular pulse according to a recording condition, so as to let the laser light source emit light through the light source driving means.
