ABSTRACT:
A recording and reproducing apparatus including a defects-list storing section for storing a defects list of a list area of an optical disk provided with a defective sector alternate function, an alternate sector storing area for storing data of an alternate sector of the optical disk, and a writing and reading controlling section for writing the defects list and the data of the alternate sector indicated by the defects list in the defects-list storing section and the alternate sector storing area when the optical disk is loaded in the main body of the apparatus. Since the data of the defective sector is written in the alternate sector storing area in advance, it is possible to read the data based on the defects list whenever necessary. Consequently, there is no need to scan the alternate sector of the optical disk, thereby reducing a lowering of the data transmission speed.
