Abstract

In some applications, constraints on the maximum run length of zeros in encoded binary data sequences is required in two different ways: the maximum run length of zeros, k, in the overall recorded sequence, and the maximum run length of zeros, k1, in the sequence of all-odd or RATE 16/17 (0,6/6) CODE - Continued all-even digit positions. The minimum run length of zeros, d, is not constrained. Such codes are identified by the parameters (d, k/k1) where d=0. The known (0, 4/4) and (0, 3/6) codes with rate 8/9 map 8-bit data bytes into 9-bit code words and these mappings are realized through simple logic equations. The (0, 6/6) code, according to the present disclosure, maps 16-bit data words into 17-bit code words.
