Improving SOVA output using extrinsic informations for bit patterned media recording
2015 IEEE International Conference on Consumer Electronics (ICCE), 2015This research proposes a new detection scheme using three extrinsic information resources supporting two-dimensional soft output Viterbi algorithm (2D SOVA) for bit patterned media recording (BPMR) that is well-known as a candidate for the next-generation magnetic storage system.

Deletion/Insertion/Reversal Error Correcting Codes for Bit-Patterned Media Recording
2011 IEEE International Symposium on Defect and Fault Tolerance in VLSI and Nanotechnology Systems, 2011Missynchronization in bit-patterned media recording (BPMR) causes deletion/insertion errors. This paper describes a model for BPMR and examines the applicability of deletion/insertion/reversal error-correcting codes based on the model. The decoded word error rates for single and double deletion/insertion/reversal error-correcting codes are compared.

9/12 Two-dimensional modulation code for bit-patterned media recording
2016 Asia-Pacific Magnetic Recording Conference Digest (APMRC), 2016This paper presents a 9/12 two-dimensional (2D) modulation code as a way to overcome 2D intersymbol interference (ISI) in bit-patterned media recording (BPMR) systems. BPMR systems are regarded as one of the promising candidates for the attainment of areal density increases that are beyond the capacities of conventional storage systems.

Scheme for utilizing the soft feedback information in bit-patterned media recording
2016 Asia-Pacific Magnetic Recording Conference Digest (APMRC), 2016This paper presents a scheme that utilizes soft feedback information obtained from a decoder to eliminate detrimental interference in bit-patterned media recording (BPMR) systems. BPMR is a promising technology that can increase the storage area density of magnetic storage systems, but one of the main challenges is to overcome 2-D spatial interference.

A Parametric Study of Inter-Track Interference in Bit Patterned Media Recording
IEEE Transactions on Magnetics, 2010We present a parametric study of inter-track interference (ITI) in the context of bit patterned media (BPM) recording channels. Bit error rate (BER) simulation results for optimal bit detection at moderate-to-high signal-to-noise-ratio (SNR) show that, in a certain range of ITI levels, increased ITI does not necessarily degrade performance.
