摘要： A method of determining an optimum recording power with respect to a rewritable optical recording medium with multiple layers. The method includes the operations of writing a recording signal to an unrecorded area of a power calibration area (PCA) of the rewritable optical recording medium using a predetermined recording power, and measuring characteristics of the recording signal, determining whether the measured recording signal characteristics have a saturation area, computing a recording power at a saturation point of the recording signal characteristics when the recording signal characteristics have the saturation area, and determining an optimum recording power by multiplying the recording power at the saturation point by a predetermined value. An optimum recording power is determined by using the saturation point of the recording signal characteristic curve such that optimum recording power can be accurately obtained when the optimum recording power is in the saturation area.
