摘要： An information recording device, an information recording method, and an information recording program capable of recording information with an appropriate modulation degree, a high asymmetry, and small waveform distortion. The information recording device applies a laser beam to a recording medium such as a DVD-R/RW and DVD+R/RW and forms a recording mark corresponding to a recording signal, thereby recording information. A recording pulse signal for forming the recording mark corresponding to the recording signal has a mark period for forming the recording mark and a space period not forming the recording mark. In test recording performed prior to actual information recording, a long mark recording power is kept constant while a short mark recording power is changed. Preferably, the short mark recording power in the test write is changed so that the asymmetry and/or the beta value is a value within a desired range.

摘要： The information recording apparatus irradiates a laser beam on a recording medium such as an optical disk and forms a recording mark corresponding to a recording signal to record information. A recording pulse signal includes a mark period irradiating the laser beam for forming the recording mark and a space period in which the recording mark is not formed. The mark period has a top pulse period and an intermediate bias period following the top pulse period. The mark period constituted by the top pulse period and the intermediate bias period does not have a continuous part of a plurality of pulses having a small pulse width unlike a pulse train, so that the correct recording mark can be stably formed on the recording medium without an inadequate deformation of a recording pulse shape, even in the case of a high speed recording.

摘要： When a bias power level of a recording pulse waveform is varied entirely or partially, a shape of the recording pulse wave form is varied according to the variation. For example, when the bias power level is increased, a width or an edge position of a top pulse or a multi-pulse of the recording pulse waveform is varied correspondingly. Thereby, a total heat quantity of a recording laser light is not increased, and a preferable recording characteristic is maintained.
