Abstract

A data encoding apparatus is provided wherein, in one aspect, bit data are encoded by using at least one kind of error-correcting code out of two kinds of error-correcting modes—random error-correcting code mode and burst error correcting code mode. The encoded bit data are then arranged in a specific two-dimensional region in a matrix to form a two-dimensional image, which is then printed on a medium. The encoded bit data may be relocated in accord with a relocation map.
