    摘要: A multi-dimensional recording (MDR) system may include a group based coding circuit (GBCC) which can implement error correcting codes via outer codes. The GBCC can implement outer codes, including interleaving outer codes, in MDR systems where inner codewords include multiple memory groupings. The multiple memory groupings may be across different structural divisions within a data storage medium; or could be across multiple different data storage mediums.

    摘要: A decoder includes cascaded lattice filters that receive encoded data and include adaptive inputs and output taps. A tap control couples a selected output tap to a viterbi input as a function of a viterbi output. A noise adaptation circuit provides adjustment to the adaptive inputs as a function of the viterbi output to whiten non-stationary noise that is received with the encoded data.
