An information recording apparatus which irradiates a laser light onto a recording medium such as a DVD+R to record information records an adjustment RF signal in a PCA used for calibration of the laser light (OPC process). Thereby, on the recording medium having no recorded area of an RF signal in an entire circumference, such as the DVD+R, it becomes possible that the adjustment RF signal is recorded in the PCA to be read out and a mechanism adjustment and the like are executed. In addition, the information recording apparatus searches the inside of the PCA in order from the area having highly possibility that the adjustment RF signal is recorded. Thereby, the adjustment RF signal in the PCA can be rapidly detected.

Information recording apparatus, information recording method and information recording program

In a DVD-R on which information is to be recorded by an information recording apparatus, prior to the recording of the information therein, there are recorded in advance at least identification information for identifying the information recording apparatus for recording the information onto the DVD-R, and recording parameter information containing optimization information for optimizing a recording state in the record processing executed by the information recording apparatus specified by the identification information. Furthermore, the information recording apparatus reads the recording parameter information at the execution of record processing to use it for the record processing.
