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.

Track Misregistration Mitigation Using CNN-Based Method on Single-Reader/Two-Track Reading BPMR Systems

IEEE Access, 2023
One of the problems that cause a decrease in the performance of the ultra-high bit-patterned magnetic recording (BPMR) system is track misregistration (TMR).

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 ...

Performance of staggered bit island spacing adjustment for a SRTR BPMR system

AIP Advances, 2023
One of the key problems facing the designer of data storage devices is how to handle the exponential rise in demand for information storage. To enhance the storage capacity of bit-patterned magnetic recording (BPMR) that stores one data bit in a single ...

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

Applied 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.

One-Dimensional Detection Using Interference Estimation by Multilayered Two-Dimensional General Partial Response Targets for Bit-Patterned Media Recording Systems

Applied Sciences, 2022
In bit-patterned media recording (BPMR) systems, two-dimensional (2D) interference, which includes intersymbol and intertrack interference from down- and across-track directions, respectively, increases when the distance between the islands is reduced ...

Large-area patterning of sub-100 nm epitaxial L10 FePt dots array via nanoimprint lithography

AIP Advances, 2015
Bit-patterned media, a promising candidate for next generation high density magnetic recording, requires sub-100 nm dots array on a wafer scale, a high degree of patterning control of the size distribution, and a material with high perpendicular ...

Numerical optimization of writer and media for bit patterned magnetic recording [PDF]

Journal of Applied Physics, 2016
In this work, we present a micromagnetic study of the performance potential of bit-patterned (BP) magnetic recording media via joint optimization of the design of the media and of the magnetic write heads. Because the design space is large and complex, we developed a novel computational framework suitable for parallel implementation on compute clusters.
