Multiproperty 16/17 trellis code

An apparatus, comprising:

• a coding system capable of encoding 16-bit input words into even parity 17-bit codewords, wherein the codewords have at least 7 ones, wherein the codewords comprise an 11-bit first half and a 6-bit second half, wherein the first half comprises at least 3 or more ones, and wherein the second half comprises at least 2 or more ones.

An apparatus, comprising:

• a coding means for coding 16-bit words into 17-bit codewords;
• and
• a filter receiving at least one of the 17-bit codewords and words based on the 17-bit codewords.

An apparatus, comprising:

• a detector outputting 17-bit codewords;
• and
• a decoding means for outputting 16-bit words by decoding at least one of the 17-bit codewords and words based on the 17-bit codewords.

A method, comprising:
