Abstract
Abstract An information recording medium includes a dot pattern recorded thereon and optically readable, and the dot pattern is formed of a group of blocks arranged in matrix. Each of the blocks has both a data dot pattern constituted of a plurality of dots arranged in accordance with the content of data and a block address pattern representing an address of the block arranged in a predetermined position in relation to the data dot pattern. The dot pattern is formed such that the same blocks in predetermined areas of the block group are overlapped in the scanning direction.
