ABSTRACT:
A read channel includes a signal receiver that receives a read back signal and a signal detector to detect symbols in the read back signal. The signal detector includes a first detector that generates raw decisions as a function of the read back signal, a post processor that identifies possible defects in the raw decisions, a selector that independently receives the raw decisions and a list of the possible defects from the first detector and the post processor, respectively, and a decoder that generates final decisions based on the raw decisions and the possible defects identified by the post processor. The decoder performs at least one of Reed-Solomon decoding, Bose Chaudhuri Hocquerghen (BCH) decoding and Hamming Decoding.
