Abstract
A first trellis code ( A, A) according to the present invention is a rate 24/26 trellis code with three (3) bytes error propagation due to EPRML minimum instance channel errors, a minimum of six (6) transitions per code word and a maximum of twelve (12) consecutive zeroes. A second trellis code ( B, B) according to the present invention is a rate 48/51 trellis code, derived from the first trellis code. The second trellis code has four (4) bytes error propagation due to EPRML minimum distance channel errors, a minimum of twelve (12) transitions per code word and a maximum of twelve (12) consecutive zeroes. A third trellis code ( C, C) according to the present invention is a rate 48/51 trellis code with four (4) bytes error propagation due to EPRML minimum distance channel errors, a minimum of fourteen (14) transitions per code word and a maximum of eleven (11) consecutive zeroes.
