ABSTRACT:
An optical recording/reproducing apparatus capable of accurately estimating the remaining service life of an optical disk without the need for recording large amounts of information on the disk beforehand. At the time of manufacture, the reflection factor in a specified blank portion of the disk is detected and the detected value recorded in a predetermined position on the disk. To estimate the remaining lifetime at a later time, the reflection factor is again detected and compared with the recorded value.
