A new construction for n-track (d, k) codes with redundancy r, referred to as (d, k; n, r) codes, is presented. This construction applies single-track (d, k+/spl Delta/k) codes (with certain extra constraints and appropriate amounts of delay) on each of the n tracks. This construction achieves a large part of the capacity increases possible when using (d, k; n, r) codes, has simple encoders and decoders, and exhibits considerable robustness to faulty tracks. It is shown that under this construction, (d, k; n, r) codes can achieve at least (n-r-1:)/n*100% of the gap in capacity between conventional (d, k) and (d, /spl infin/) codes. Several practical examples of (d, k; n, r) codes under this construction are presented.>
