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

Engineering 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).
