power calibration area (PCA)

On recordable compact discs (CD-R), there is a specified area for calibrating the laser beam called the Power CalibrationArea

(PCA). This PCA area is used when writing a compact disc to adjust the power of the laser to the CD-R. The Power Calibration Area (PCA), along with the Program Memory Area (PMA), is located near the inner track, before the header, the lead-in. The PCA area starts at -35 seconds, the PMA area at -13 seconds.
