PROBLEM TO BE SOLVED: To provide a method and a device for recording information, which can record a mark having a proper shape even in the case of high-speed recording. SOLUTION: The information recording device allows to irradiate a recording medium like an optical disk with laser light and forms a recording mark according with a recording signal to record information. A recording pulse signal consists of a mark period for irradiating with the laser light to form the recording mark and a space period when the recording mark is not formed, and the mark period has a top pulse period and an intermediate bias period following the top pulse period. Since the mark period having the top pulse period and the intermediate bias period doesn't have a consecutive part of a plurality of pulses having a short pulse width like a pulse train in a conventional write strategy, a recording pulse waveform is not improperly deformed regardless of increase of the recording speed, and a correct recording mark can be stably formed on the recording medium. |
