ABSTRACT:
A system for correcting two [tracks] bytes in error in each code word of a [multi-track] multi-code word data arrangement is provided. The message data Z.sub.1, Z.sub.2, . . . Z.sub.k is encoded by adding two check bytes C.sub.1 and C.sub.2 thereto which are generated from the message data which is arranged in blocks of k bytes, where each byte has f bits of data, [arranged in a cross track direction] where f = b .times. m and m and b are integers >1 and k is an integer 2<k<2.sup.b. The check bytes are generated in accordance with the equations:
