ABSTRACT:
An optical recording/reproducing apparatus arranged to perform verification processing on whether or not information has been correctly recorded in a target sector of an optical recording medium by reproducing the information. If the target sector is determined to be defective, linkage information about the correspondence between the target sector and an alternative sector is stored/recorded and the verify processing is continued until a non-defective alternative sector is detected. Thus, only linkage information about the correspondence between the non-defective sector and the target sector is registered and linkage information about the corespondence between the defective alternative sector and the target sector is erased.
