Multi-Track Iterative ITI Canceller for Shingled Write Recording
Masaaki Fujii, Nobuhiko Shinohara (Samsung Yokohama) MR2010-44
Abstract (in Japanese) (See Japanese page) 
(in English) An iterative inter-track-interference (ITI) cancelling scheme is described for multi-track signal detection in shingled-write-recoding systems. This multi-track iterative ITI canceller consists of multi-track ITI- and ISI-signal soft cancellers, two-dimensional partial-response (TDPR) filters, noise-predictive max-log-MAP detectors, and LDPC decoders. TDPR filters using ITI-suppressing tap coefficients mitigate ITI in the first iteration of the scheme. The multi-track ITI- and ISI-signal soft cancellers and the TDPR filters (which are adjusted to the residual two-dimensional ISI signals) efficiently detect multi-track signals in the latter iterations. Computer simulation results in media-noise-dominant environments demonstrate that the proposed multi-track iterative ITI canceller achieves bit error rates close to those obtained in a non-ITI case when the read-head off-track ratio is up to 50%.
