ABSTRACT:
In an error correction encoding system, information codes in the form of a data matrix having row addresses and column addresses are stored in memory. A first error correction encoder extracts the stored addresses from the data matrix in the oblique direction and produces a first error-correcting code word from the information codes extracted in the oblique direction. The information codes are extracted in the oblique direction every n row addresses (where n is an integer equal to or greater than 2). A second error correction encoder extracts the information codes from the data matrix in the row direction and produces a second error-correcting code word from the information codes extracted in the row direction.
