  • WRITING POWER CALIBRATING METHOD AND DATA RECORDING APPARATUS USING THE SAME
    Publication number: 20080084805
    Abstract: A power calibrating method includes steps of: determining a target value for a front monitor diode signal; outputting light with a power having a writing power level and an erasing power level, durations of the writing power level being identical to durations of the erasing power level; obtaining multiple values of the front monitor diode signal and an average of the multiple values of the front monitor diode signal; and adjusting the writing power level until the average of the multiple values of the FMD signal equals to the target value.
