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.

The effects of both inter-track interference and inter-symbol interference are the main hindrances in alternated magnetic recording technologies such as bit-patterned magnetic recording. To increase an areal density of hard disk drives over 1 terabit per square inch; therefore, these two effects must be coped with some powered signal processing ...

Bidirectional Decision Feedback Modified Viterbi Detection (BD-DFMV) for Shingled Bit-Patterned Magnetic Recording (BPMR) With 2D Sectors and Alternating Track Widths

IEEE Journal on Selected Areas in Communications, 2016
Shingled bit-patterned media (BPM) recording is a promising candidate to improve the magnetic recording density above 1 Tb/in2 while keeping the conventional writer design. However, shingled magnetic recording (SMR) leads to a narrower track pitch, and thus increased inter-track interference motivating the investigation of array readers and 2-D sectors.
