Modulation Code for Reducing Intertrack Interference on Staggered Bit-Patterned Media Recording

open access: yesApplied Sciences, 2020
A bit-patterned media recording (BPMR) system is a type of ultrahigh-capacity magnetic storage system that can extend to an areal density of 1 terabit per square inch or higher.

Iterative Signal Detection Scheme Using Multilayer Perceptron for a Bit-Patterned Media Recording System

open access: yesApplied Sciences, 2020
Because of the physical and engineering problems of conventional magnetic data storage systems, bit-patterned media recording (BPMR) is expected to be a promising technology for extending the storage density to beyond 1 Tb /in2.

A simple 2D modulation code in single-reader two-track reading BPMR systems

open access: yesDigital 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).

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

open access: yesDigital 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

LDPC product coding scheme with extrinsic information for bit patterned media recoding

open access: yesAIP Advances, 2017
Since the density limit of the current perpendicular magnetic storage system will soon be reached, bit patterned media recording (BPMR) is a promising candidate for the next generation storage system to achieve an areal density beyond 1 Tb/in2.

Long-Short Term Memory-Based Application on Adaptive Cross-Platform Decoder for Bit Patterned Magnetic Recording

open access: yesIEEE Access, 2020
Dynamic bit encoding and decoding of the magnetic recording process remain a challenge in that the process is restrained by the balance between reading and writing performance of the decoder's bit error rate (BER).
