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

Role of CoFeB thickness in electric field controlled sub-100 nm sized magnetic tunnel junctions

open access: yesAIP Advances, 2018
We report a comprehensive study on the role of the free layer thickness (tF) in electric-field controlled nanoscale perpendicular magnetic tunnel junctions (MTJs), comprising of free layer structure Ta/Co40Fe40B20/MgO, by using dc magnetoresistance and ...

Generalized Brewster effect in dielectric metasurfaces

open access: yesNature Communications, 2016
Devices with greater freedom are desired in nanophotonics. Here, the authors demonstrate theoretically and experimentally that the generalized Brewster effect can be observed in an all-dielectric metasurface potentially for any angle, wavelength and ...

Deductive Optimization of Relational Data Storage

open access: yes, 2020
Optimizing the physical data storage and retrieval of data are two key database management problems. In this paper, we propose a language that can express a wide range of physical database layouts, going well beyond the row- and column-based methods that

On Secure Distributed Data Storage Under Repair Dynamics [PDF]

open access: yes, 2010
We address the problem of securing distributed storage systems against passive eavesdroppers that can observe a limited number of storage nodes. An important aspect of these systems is node failures over time, which demand a repair mechanism aimed at ...
