OPTIMAL POWER CALIBRATION METHOD AND DATA RECORDING APPARATUS USING THE SAME

摘要

An optimal power calibration method includes steps of: performing a first optimal power calibration procedure at a first power calibration area with a first recording speed to obtain a first optimal power level corresponding to the first recording speed; performing a second optimal power calibration procedure at a second power calibration area with a second recording speed to obtain a second optimal power level corresponding to the second recording speed, the second recording speed being higher than the first recording speed; and determining an optimal recording power level for recording data on a disc at a predetermined speed based on the first optimal power level and the second optimal power level.
