Abstract

PURPOSE: To deal a bit of information of a 1st defective management area as a fixed amt. and to reduce the capacity of a RAM to be stored with the information by registering a defective area to be generated after the time when an initial defective area of an information recording medium is registered in a 1st defective management area in a 2nd defective management area.
CONSTITUTION: Data recording area 2 is the area for recording and reproducing the user's data and a bit of information of the defective management area. Moreover, for instance, a 1st discriminating bit 6 for discriminating between the user's data area and the defective management area and a 2nd discriminating bit 7 for discriminating between the 1st defective management area and the 2nd defective management area are provided as a part of information bits of a data train in a leading part in a header 1. Thus, by disposing two discriminating bits in the header, the user's data area, the 1st defective management area and the 2nd defective management area can surely be discriminated for every sector. Consequently, when the 1st defective management area is put on the RAM, the capacity of the RAM can be decreased.
