Improving Serial Detection Using MAP Algorithm for Bit-Patterned Media Recording
Applied Sciences, 2022 Bit-patterned media recording (BPMR) is a promising technology for increasing the areal density (AD) of magnetic data storage systems. In BPMR, the non-magnetic zone is reduced to increase AD, which causes serious problems such as two-dimensional (2D ...

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).
