A concatenated LDPC-marker code for channels with correlated insertion and deletion errors in bit-patterned media recording system. [PDF]

PLoS ONE, 2022
Most synchronization error correction codes deal with random independent insertion and deletion errors without correlation. In this paper, we propose a probabilistic channel model with correlated insertion and deletion (CID) errors to capture the data ...

Micromagnetic Simulation of L1₀-FePt-Based Exchange-Coupled-Composite-Bit-Patterned Media with Microwave-Assisted Magnetic Recording at Ultrahigh Areal Density [PDF]

Micromachines, 2021
In this work, we propose exchange-coupled-composite-bit-patterned media (ECC-BPM) with microwave-assisted magnetic recording (MAMR) to improve the writability of the magnetic media at a 4 Tb/in2 recording density.

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 ...

Modulation Decoding Based on K-Means Algorithm for Bit-Patterned Media Recording

Applied Sciences, 2022
In bit-patterned media recording (BPMR) systems, the readback signal is affected by neighboring islands that are characterized by intersymbol interference (ISI) and intertrack interference (ITI).
