ABSTRACT:
An optical disk stores the error management information indicating error areas, which are found in manufacturing an optical disk and in recording information, and the error management information further indicating areas used as substitutions of the error areas. An optical disk apparatus reads out of the optical disk the error management information indicating the in-manufacturing and in-recording error areas and the substitution areas, and stores the readout information into a memory buffer. A controller of the optical disk apparatus checks whether an area to be accessed in recording or reproducing the information into and from the optical disk is the error area or not by referring the error management information in the buffer memory.
