In method and apparatus for calibrating laser write power for writing data onto an optical storage medium, test data is written onto a test area of the optical storage medium at a number (N) of laser power levels. The test data written onto the test area is read and processed so as to generate a number (N) of processed signals corresponding to the number (N) of laser power levels, respectively. A jitter value associated with each of the processed signals is determined. Finally, one of the laser power levels that corresponds to one of the processed signals having the jitter value that is at a relative minimum is selected. The laser write power is set to the selected one of the laser power levels.
