<p>In an optical recording system employing a laser for writing digital data onto a storage medium, an apparatus and method for calibrating a laser to a power level which minimizes write errors. A calibration profile (300) is generated by writing test data patterns (506) onto the storage medium by using a number of different predetermined laser power levels. The test data patterns are then read back (525). The number of write errors is determined (526) for each of the different laser power levels by comparing the written data patterns to the read back data patterns. The calibration profile (300) denotes the number of write errors as a function of laser power levels. Next, an optimum laser power corresponding to a minimum number of write errors is determined according to the calibration profile (300). The laser is calibrated to this optimum power level.</p> |
