Abstract

PURPOSE: To facilitate the rewriting of recorded data by executing rewrite onto a recorded block in accordance with a special write command.
CONSTITUTION: An MPU 11 receives a command from a high-order host device 2, and when this command is a 'special write command', even if it is detected that a block designated by the command is written already, it is executed without setting it as an error, and by controlling a read/write control circuit 14, write is executed to a designated recorded block of an optical disk medium 16. In the circuit 14, it is detected that write data is not reproduced normally by read-out after recording, a shift processing factor generating means 141 generates a shift processing factor, and the MPU 11 checks up an idle state of a shift area, based on a shift processing procedure, assigns the shift area and executes write of data.
