Abstract
A storage device comprising a modulation encoder and decoder, an error-correction encoder and decoder, and a metric computation module. The modulation encoder and decoder provide a modulation code for data stored on the storage device. The error-correction encoder and decoder provide an error-correcting code for data to be written on the storage device. The metric computation module is coupled with the modulation decoder to compute conditional probabilities using recovered read-back channel parameters of the storage device.
