Single-Track equalization method with TMR correction system based on cross correlation functions for a patterned media recording system

open access: yesEngineering and Applied Science Research, 2017
Bit-patterned media recording (BPMR) is a promising technology for ultra-high density media, however, there are some challenges that need to be addressed including two-dimensional (2D) interference, and track mis-registration (TMR).

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.

Soft-information flipping approach in multi-head multi-track BPMR systems

open access: yesAIP Advances, 2018
Inter-track interference is one of the most severe impairments in bit-patterned media recording system. This impairment can be effectively handled by a modulation code and a multi-head array jointly processing multiple tracks; however, such a modulation ...
