This paper proposes two-dimensional unidirectional clustered error correcting codes suitable for high-density two-dimensional matrix symbols. These codes are capable of correcting unidirectional errors confined in a rectangle having lm rows and ln columns. Evaluation shows that the proposed codes have smaller number of check bits than the existing codes.
