Abstract:
Methods are provided for pattern-dependent log likelihood ratio (LLR) manipulation of a hard disk drive detector output. Generally, by observing a pattern dependency of LLRs, various rules for LLR manipulation at the detector output are outlined. The rules may provide more reliable LLR values, such as by improving signal-to-noise ratio (SNR) of the hard disk drive detector output.
