The optimum power calibration area is a special area near the center of the recordable CD. Before writing a track on a CD, the CD-Recorder must adjust the amount of power applied to the writing laser for the optimum level for the mounted CD. The optimum calibration area is reserved for this purpose. If this area becomes full, the CD-Recorder can't write to the CD.
The power calibration failed, possibly because a defective CD was mounted or an internal hardware malfunction occurred in the CD-Recorder.
Insert a blank CD and repeat the CD creation process. If the error persists, contact the CD-Recorder manufacturer for more information.
Try a different brand of CD-R media.
