Abstract

PURPOSE:To reduce the time loss of software and an upper device by performing the defective sector flag processing and the alternate sector processing for a defective sector in a disc processing device. CONSTITUTION:If a pertinent sector is judged to be a defective sector during the write operation because of error detection, the address of an alternate sector is searched, and the coincidence of the sector address is checked by the output of an ID detecting part 10; and when the coincidence is detected, data stored in a write buffer 3 during the write operation is selected by a selector 4 and is written onto a disc 6 through a read/write part 5. After this operation is terminated, the sector which is judged to be defective in the write operation is searched; and when the coincidence of the sector address is detected by the ID detecting part 10, a defect flag is generated by a defect flag generating part 9 and is written onto the disc 6 through the selector 4 and the read/write part 5 to defining this sector as a defective sector, thus completing the alternate sector processing.
