A method of optimal power calibration adapted to an optical storage medium such as a rewritable (CD-RW) disk is disclosed. The method takes the advantages of rewritable characteristic defined in the Orange Book to perform a plurality of optimal power calibration (OPC) processes on the power calibration area allocated in inner track and several recording positions on the rewritable disk. The OPC processes write erasable patterns such as the "Sub Q mode 0" pattern define in Orange Book on data written area(s) of the rewritable disk so that these erasable patterns will be overwritten by sequentially recording data. A relation curve, which indicates the relationships between optimal recording powers of a recording position and the distance from the center of the rewritable disk to the recording position, is then established by using the optimal recording powers measured from the aforementioned OPC processes. Required optimal recording power of any recording position can thus be mapped out from the relation curve under data recording operations.
