Two-dimensional magnetic recording (TDMR) is a novel recording architecture intended to support densities beyond those of conventional recording systems. The gains from TDMR come primarily from more powerful coding and signal processing algorithms that allow the bits to be packed more tightly on the disk, and yet be retrieved with acceptable error rates. In this paper, we present some preliminary...
A novel constrained parity-check code with post-processing is presented in this paper for improving the bit error rate performance on perpendicular recording channels. The particular design of the parity-check code results in a post-processor, that is computationally much simpler than conventional post-processors. We also examine the optimality of the post-processors used in current systems. The proposed...
