ABSTRACT:
A method for controlling an optical disk apparatus when writing information into a defective sector, by storing a management table for alternate process in a memory for control, and by writing the management table into a storage medium. When a writing operation is abnormally ended in an anomalous state and when the alternate process is consecutively repeated for a defective sector, an upper limit of times of alternate process is set. When the number of alternate processes repeated reaches a preset number, the writing is suspended. Updating of the management table for alternate process may be inhibited.
