2023 IEEE International Magnetic Conference - Short Papers (INTERMAG Short Papers), 2023
In the bit-patterned media recording (BPMR), to increase the areal density, the magnetic islands are adjusted closer together. This makes the bit-error rate performance of BPMR become worse by inter-symbol interference (ISI) and inter-track interference (

Bit-Flipping Scheme Using K-Means Algorithm for Bit-Patterned Media Recording
IEEE transactions on magnetics, 2022As the need for storing significant amounts of data has increased, an increased areal density (AD) of hard disk drives is required. Bit-patterned media recording (BPMR) with the ability to increase AD is regarded as one of the future magnetic storage ...

Track Mis-Registration Estimator Based on K-Means Algorithm for Bit-Patterned Media Recording
IEEE transactions on magnetics, 2022Bit-patterned media recording (BPMR) has been considered among the key technologies to extend recording densities to 1 Tb/in2 and beyond. However, the BPMR system encounters the challenges of two-dimensional intersymbol interference and track mis ...

2022 IEEE 33rd Magnetic Recording Conference (TMRC), 2022
In bit patterned media recording (BPMR) technology, data are stored on the magnetic islands. Thus, for increasing the areal density (AD), we have to reduce the distance between magnetic islands.

Soft Information Scheme Based Multilayer Perceptron in Coded Bit-Patterned Media Recording System
International Symposium on Intelligent Signal Processing and Communication Systems, 2022In order to increase the efficiency of the recording system, both the inter-symbol interference (ISI) and inter-track interference (ITI) effects that impede the increase of an areal density (AD) in an ultra-high magnetic recording system, such as a bit ...

An Intertrack Interference (ITI) Subtraction Scheme for Bit-Patterned Media Recording
International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology, 2021Currently, hard disk drive has been struggled to overcome the super-paramagnetic limit that restricts the density increment. Bit-patterned magnetic recording (BPMR) is a candidate that can increase an areal density (AD) up to 4 Tb/in2.
