ABSTRACT:
It is an object of the present invention to realize a data recording disk that is resistant against burst errors and capable of quick access without sacrificing recording capacity. A disk 1 is divided into zones, and the number of sectors per track is made larger by one in a more outside zone than in a more inside zone. The disk 1 is driven at a constant rotational angular velocity. The sector is composed of an address area and a data area, and it is arranged for the address recorded in the address area to complete error detection and correction processing within the address area. An error detection and correction code in the data area is completed extending over a plurality of sectors.
