In the recording format, the data recording region is sectioned into bands having a width corresponding to an appropriate number of data-bit lines to form blocks. Each of the blocks is provided with an identifier to allow the access by block units. Each of the blocks may be formed of a group of data-bit lines and check bit line. Each block may have a plurality of sectors. The blocks may be sectioned by boundary information lines having a specific code pattern.
