Abstract

PURPOSE: To shorten the information processing time in an information recording mode by enabling an optical disk itself to apply the substitute processing to a defective area in an initial mode or a recording mode.
CONSTITUTION: A block number to be recorded via a host computer is supplied to a control circuit 20 in a state where the latest defect control information is stored in a buffer memory 43 from an optical disk 1. The circuit 20 checks whether the received block number is included or not in the initial defective area information (g) on the buffer 43. In so, the substitute block read out of the information (g) is defined as a block to be recorded. Then the recorded block is read. If a correction error occurs, the circuit 20 decides the next substitute block based on the recording mode defective substitute area information (h) and records information again to this block. Then the recorded block is read and the circuit 20 records again said record data to another substitute block if a defect occurs.
