Design of Patterned Magnetic Recording Media for Tera-Bit Recording [PDF]

open access: yes
Specifications of patterned magnetic recording media for tera-bit recording were designed as an extension of perpendicular magnetic recording. Effective thermal stability of the magnetic dots with perpendicular anisotropy was estimated using the magnetic

ADVANCED SIGNAL PROCESSING FOR MAGNETIC RECORDING ON PERPENDICULARLY MAGNETIZED MEDIA [PDF]

open access: yes, 2010
In magnetic recording channels (MRCs) the readback signal is corrupted by many kinds of impairments, such as electronic noise, media noise, intersymbol interference (ISI), inter-track interference (ITI) and different types of erasures.

Graph Neural Network (GNN) for Joint Detection–Decoder MAP–LDPC in Bit-Patterned Media Recording Systems

open access: yes
With its high area density, bit-patterned media recording (BPMR) is emerging as a leading technology for next-generation storage systems. However, as area density increases, magnetic islands are positioned closer together, causing significant two ...

2021 36th International Technical Conference on Circuits/Systems, Computers and Communications (ITC-CSCC), 2021
Among the alternate ultra-high density data storage technologies, bit-patterned media recording (BPMR) is one of the mentioned technologies that was proposed to achieve a higher density. Due to the closeness between the magnetic islands, so the readback sequences are disrupted from the effect of two-dimensional (2D) interference, which includes both ...

Optimization of Bit-Patterned Media Recording (BPMR) System via Tolerance Design

IEEE Transactions on Magnetics, 2013
Bit-patterned media recording (BPMR) is a promising approach to push back the onset of the superparamagnetic limit faced by conventional granular media recording (CGMR). Previous work in this area has characterized the position jitter and size jitter from fabricated media at recording densities ranging from 0.6 Tera dots per square inch (Tdpsi) to 2.9 ...
