A method and apparatus for determining an optimal writing power for recording data on a recording medium such as an optical disk, are discussed. The method according to an aspect of the present invention includes (a) performing an optimal power calibration (OPC) operation on a first area of the recording medium, and detecting a first writing power based on the OPC operation performed on the first area; (b) performing an OPC operation on a second area of the recording medium after erasing data on the second area, and detecting a second writing power based on the OPC operation performed on the second area; and (c) determining an optimal writing power for recording data on the recording medium based on the detected first and second writing powers.
