摘要： Based on actual recording power information obtained during test writing, a recording power is efficiently controlled with high accuracy during actual recording. An information recording apparatus irradiates a laser light onto an information recording medium such as an optical disc to record data and reproduce the recorded data. In recording actual data such as data designated by a user, the information recording apparatus temporarily stops recording at the time when predetermined amount of data is recorded, and confirms recording quality. Namely, the apparatus reproduces the recorded data and determines the recording quality based on the reproduced data. When it is determined that the recording quality is within an appropriate range, the recording of the actual data is continued at the recording power. Meanwhile, when it is determined that the recording quality is out of the appropriate range, the recording power is corrected so that the recording quality becomes within the appropriate range, and the actual data is recorded. Thereby, even when the optimum recording power is changed due to some causes and condition change after recording start of the actual data, the recording power can be correspondently corrected, and accurate information recording with the appropriate recording power can be realized.

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.
