Inter-track interference mitigation with two-dimensional variable equalizer for bit patterned media recording [PDF]

AIP Advances, 2017
The increased track density in bit patterned media recording (BPMR) causes increased inter-track interference (ITI), which degrades the bit error rate (BER) performance.

Information Geometry-Based Two-Stage Track-Before-Detect Algorithm for Multi-Target Detection in Sea Clutter [PDF]

Entropy
To address the challenges of radar multi-target detection in marine environments, this paper proposes an information geometry (IG)-based, two-stage track-before-detect (TBD) framework.

Parallel Detection Based on a Generalized Partial Response Target for Staggered Bit-Patterned Media Recording Systems

IEEE Access, 2022
We consider a prospective island distribution of bit-patterned media recording (BPMR) that consists of a hexagonal array called a staggered BPMR. Although the staggered BPMR can reduce two-dimensional interference, including inter-symbol interference ...

An iterative ITI cancellation method for multi-head multi-track bit-patterned magnetic recording systems

Digital Communications and Networks, 2021
Bit-Patterned Magnetic Recording (BPMR) is one of the emerging data storage technologies, which promises an Areal Density (AD) of about 4 Tb/in2. However, a major problem practically encountered in a BPMR system is Inter-Track Interference (ITI) that can

Constrained codes in single-reader/two-track reading bit-patterned magnetic recording

AIP Advances, 2021
A reduction in track width of ultra-high density magnetic recording such as bit-patterned media recording (BPMR) results in an increase in areal density.

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).
