Estimating Interference with a Two-Dimensional Viterbi Algorithm for Bit-Patterned Media Recording
Applied Sciences, 2022 Bit-patterned media recording (BPMR) is proposed as a candidate for future magnetic data storage to overcome superparamagnetism. The distance between magnetic islands in BPMR must be reduced to increase the areal density (AD).

A simple 2D modulation code in single-reader two-track reading BPMR systems
Digital Communications and Networks, 2021 A reduction in the track width of magnetic recording systems results in a welcome increase in Areal Density (AD), but can severely deteriorate system performance in the unfortunate appearance of extreme Inter-Track Interference (ITI).

Coding for Correcting Insertions and Deletions in Bit-Patterned Media Recording [PDF]
2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011 Bit-patterned media is a novel technology for magnetic data storage that is poised to increase recording density beyond 1 Tb/sq. in. However, a significant concern in BPMR is the stringent requirements for synchronization between write clock and island position, errors in which may manifest as insertions and deletions.
