Abstract: The present invention relates to apparatus and method of determining an optimal writing power for an aged writable disk after checking whether a writable disk is aged or not. The present invention reads signals written on a writable disk, judges whether or not the writable disk is aged based on a signal characteristic, e.g., a level difference between the read signals before and after an equalization and jitter of the read signals, and conducts an OPC at least twice for the writable disk to obtain a precise optimal writing power if judged to be aged. The precise optimal writing power can prevent deterioration of reproduction characteristic of recorded data even though an aged writable disk is used.
