ABSTRACT:
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+\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 
this construction can achieve at least (n-r-1)/n*100\% of the gap 
between conventional (d,k) and (d,\infty ) codes . Several practical 
examples of (d,k;n,r) codes under this construction are presented.
