This paper presents a low-complexity two-dimensional (2D) detection strategy for shingled magnetic recording (SMR) media. The detection strategy involves the use of multi-level 2D BCJR detector along-track for inter-symbol interference (ISI) cancellation and regular BCJR detector across tracks for inter-track interference (ITI) cancellation. This is applied in a multi-track two dimensional magnetic...
A combination of single parity check-code and Two-Dimensional (2D) Bahl Cocke Jelinek Raviv (BCJR) detector is used in this paper for joint detection and decoding of 2D interference channel. This is applied to a multi-track two dimensional magnetic recording (TDMR) system. The multi-level 2D BCJR detector handled the code constraint while performing joint detection and single parity decoding. Two...
High density recording requires high complex decoders/detectors for handling the interference of symbols both across and along the tracks. In this paper, we present a new interleaved constrained single parity-check code with Balh Coke Jelinek Raviv (BCJR) detector. The BCJR detector handled the code constraints whereas the dithered relative prime (DRP) and the square interleaver provided adequate...
