ABSTRACT:
An apparatus according to the present invention is designed to perform formatting processing on an information storage medium. The storage medium has a data storage area including a user data area and a spare area. The user data area is provided to write user data on, while the spare area includes a replacement block to be used as a replacement for a block that has been detected as a defective block. The replacement block stores instruction information that instructs to read data from the defective block when data is read from the replacement block. The apparatus includes a control section for controlling the formatting processing. In performing the formatting processing, the control section updates information stored in the replacement block such that when data is read from the replacement block, the data is not read from the defective block.
